We're dividing 38526641 by 602 
The aim is to understand the frequency of 602 in 38526641.

Going ahead to step 1:
When dividing 3 by 602, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 602

On to step 2:
602 goes into 38 0 times with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 602

Let's proceed to step 3:
602 goes into 385 0 times with a remainder of 385.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 385 after subtracting 0 from 385.
Include the next digit (2) from the dividend after 385, then repeat: 3852 / 602

On to step 4:
3852 divided by 602 is 6 with a remainder of 240.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 240 after subtracting 3612 from 3852.
Fetch the next digit (6) from the dividend, attach it to 240 and continue: 2406 / 602

Going ahead to step 5:
602 goes into 2406 3 times with a remainder of 600.
The next digit of our result is 3. 
Result so far: 63.0
Deduct 1806 from 2406 and we're left with 600.
Append the next digit (6) from the dividend to 600 and continue with: 6006 / 602

Moving on to step 6:
When dividing 6006 by 602, we get 9 with a remainder of 588.
Use 9 as the next digit of our solution. 
Result so far: 639.0
Subtracting 5418 from 6006 leaves us with 588.
Bring next digit (4) of the dividend behind the 588 and repeat the process: 5884 / 602

Going ahead to step 7:
The number 602 fits into 5884 9 times, leaving a remainder of 466.
Write down 9 as next digit of the result. 
Result so far: 6399.0
Subtract 5418 from 5884 to get 466.
Grab the next digit (1) from the dividend, add it to 466, then carry on: 4661 / 602

Let's proceed to step 8:
If we divide 4661 by 602, we get 7 and a remainder of 447.
The number 7 becomes the next digit in our result. 
Result so far: 63997.0
If we take 4214 away from 4661, we end up with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Step 9:
The number 602 fits into 4470 7 times, leaving a remainder of 256.
Record the quotient 7 as the next digit in the result. 
Result so far: 63997.7
Subtract 4214 from 4470 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 10:
2560 divided by 602 is 4 with a remainder of 152.
Put 4 as the next digit of the answer. 
Result so far: 63997.74
Subtract 2408 from 2560 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 11:
602 can be fit into 1520 2 times, resulting in a remainder of 316.
The number 2 becomes the next digit in our result. 
Result so far: 63997.742
The remainder is 316 after subtracting 1204 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 12:
When dividing 3160 by 602, we get 5 with a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 63997.7425
The remainder is 150 after subtracting 3010 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 13:
602 can be fit into 1500 2 times, resulting in a remainder of 296.
Record the quotient 2 as the next digit in the result. 
Result so far: 63997.74252
If we take 1204 away from 1500, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 14:
2960 divided by 602 is 4 with a remainder of 552.
Use 4 as the next digit of our solution. 
Result so far: 63997.742524
If we subtract 2408 from 2960, we get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 15:
The number 602 fits into 5520 9 times, leaving a remainder of 102.
Put 9 as the next digit of the answer. 
Result so far: 63997.7425249
If we take 5418 away from 5520, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 16:
1020 divided by 602 is 1 with a remainder of 418.
Write down 1 as next digit of the result. 
Result so far: 63997.74252491
If we take 602 away from 1020, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

The final result is 63997.74252491 with a remainder of 4.18e-07.
