Let's divide 99321459 by 602
The aim is to understand the frequency of 602 in 99321459.

Step 1:
When dividing 9 by 602, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 602

Advancing to step 2:
602 can be fit into 99 0 times, resulting in a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Fetch the next digit (3) from the dividend, attach it to 99 and continue: 993 / 602

Let's proceed to step 3:
993 divided by 602 is 1 with a remainder of 391.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 602 from 993 to get 391.
Bring next digit (2) of the dividend behind the 391 and repeat the process: 3912 / 602

Let's proceed to step 4:
3912 divided by 602 is 6 with a remainder of 300.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 300 after subtracting 3612 from 3912.
Fetch the next digit (1) from the dividend, attach it to 300 and continue: 3001 / 602

Let's proceed to step 5:
602 can be fit into 3001 4 times, resulting in a remainder of 593.
The next digit of our result is 4. 
Result so far: 164.0
If we take 2408 away from 3001, we end up with 593.
Bring next digit (4) of the dividend behind the 593 and repeat the process: 5934 / 602

Going ahead to step 6:
If we divide 5934 by 602, we get 9 and a remainder of 516.
Put 9 as the next digit of the answer. 
Result so far: 1649.0
The remainder is 516 after subtracting 5418 from 5934.
Append the next digit (5) from the dividend to 516 and continue with: 5165 / 602

On to step 7:
The number 602 fits into 5165 8 times, leaving a remainder of 349.
Use 8 as the next digit of our solution. 
Result so far: 16498.0
If we subtract 4816 from 5165, we get 349.
Grab the next digit (9) from the dividend, add it to 349, then carry on: 3499 / 602

Moving on to step 8:
If we divide 3499 by 602, we get 5 and a remainder of 489.
Put 5 as the next digit of the answer. 
Result so far: 164985.0
Subtract 3010 from 3499 to get 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

On to step 9:
602 goes into 4890 8 times with a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 164985.8
The remainder is 74 after subtracting 4816 from 4890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 10:
If we divide 740 by 602, we get 1 and a remainder of 138.
Record the quotient 1 as the next digit in the result. 
Result so far: 164985.81
The remainder is 138 after subtracting 602 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 11:
1380 divided by 602 is 2 with a remainder of 176.
Record the quotient 2 as the next digit in the result. 
Result so far: 164985.812
Subtract 1204 from 1380 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 12:
1760 divided by 602 is 2 with a remainder of 556.
The number 2 becomes the next digit in our result. 
Result so far: 164985.8122
Deduct 1204 from 1760 and we're left with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

In conclusion, the division gives 164985.8122 with a balance of 0.00556.
