We look at the division of 97050607 by 602 
The aim is to understand the frequency of 602 in 97050607.

Advancing to step 1:
602 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 602

Advancing to step 2:
The number 602 fits into 97 0 times, leaving a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 97, we end up with 97.
Fetch the next digit (0) from the dividend, attach it to 97 and continue: 970 / 602

Moving on to step 3:
The number 602 fits into 970 1 times, leaving a remainder of 368.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 368 after subtracting 602 from 970.
Append the next digit (5) from the dividend to 368 and continue with: 3685 / 602

On to step 4:
When dividing 3685 by 602, we get 6 with a remainder of 73.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 3612 from 3685 leaves us with 73.
Fetch the next digit (0) from the dividend, attach it to 73 and continue: 730 / 602

On to step 5:
When dividing 730 by 602, we get 1 with a remainder of 128.
Write down 1 as next digit of the result. 
Result so far: 161.0
The remainder is 128 after subtracting 602 from 730.
Bring next digit (6) of the dividend behind the 128 and repeat the process: 1286 / 602

Let's proceed to step 6:
If we divide 1286 by 602, we get 2 and a remainder of 82.
Put 2 as the next digit of the answer. 
Result so far: 1612.0
If we subtract 1204 from 1286, we get 82.
Take the next digit (0) from the dividend and append it to 82, then repeat: 820 / 602

Step 7:
602 can be fit into 820 1 times, resulting in a remainder of 218.
Use 1 as the next digit of our solution. 
Result so far: 16121.0
The remainder is 218 after subtracting 602 from 820.
Bring next digit (7) of the dividend behind the 218 and repeat the process: 2187 / 602

Moving on to step 8:
602 goes into 2187 3 times with a remainder of 381.
Write down 3 as next digit of the result. 
Result so far: 161213.0
If we subtract 1806 from 2187, we get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Let's proceed to step 9:
If we divide 3810 by 602, we get 6 and a remainder of 198.
Write down 6 as next digit of the result. 
Result so far: 161213.6
Subtracting 3612 from 3810 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 10:
If we divide 1980 by 602, we get 3 and a remainder of 174.
The number 3 becomes the next digit in our result. 
Result so far: 161213.63
Subtracting 1806 from 1980 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 11:
When dividing 1740 by 602, we get 2 with a remainder of 536.
The next digit of our result is 2. 
Result so far: 161213.632
The remainder is 536 after subtracting 1204 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

On to step 12:
602 can be fit into 5360 8 times, resulting in a remainder of 544.
The next digit of our result is 8. 
Result so far: 161213.6328
The remainder is 544 after subtracting 4816 from 5360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 13:
602 can be fit into 5440 9 times, resulting in a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 161213.63289
The remainder is 22 after subtracting 5418 from 5440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
602 can be fit into 220 0 times, resulting in a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 161213.63289
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 15:
602 can be fit into 2200 3 times, resulting in a remainder of 394.
Write down 3 as next digit of the result. 
Result so far: 161213.6328903
The remainder is 394 after subtracting 1806 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Moving on to step 16:
602 can be fit into 3940 6 times, resulting in a remainder of 328.
Write down 6 as next digit of the result. 
Result so far: 161213.63289036
Subtracting 3612 from 3940 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

After the division, we end up with 161213.63289036 and a remainder of 3.28e-07.
