We're dividing 72099188 by 963 
The aim is to understand the frequency of 963 in 72099188.

Advancing to step 1:
7 divided by 963 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 963

Advancing to step 2:
When dividing 72 by 963, we get 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Take the next digit (0) from the dividend and append it to 72, then repeat: 720 / 963

On to step 3:
963 goes into 720 0 times with a remainder of 720.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 720, we get 720.
Fetch the next digit (9) from the dividend, attach it to 720 and continue: 7209 / 963

Going ahead to step 4:
If we divide 7209 by 963, we get 7 and a remainder of 468.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 6741 from 7209 and we're left with 468.
Bring next digit (9) of the dividend behind the 468 and repeat the process: 4689 / 963

Let's proceed to step 5:
4689 divided by 963 is 4 with a remainder of 837.
Write down 4 as next digit of the result. 
Result so far: 74.0
If we subtract 3852 from 4689, we get 837.
Fetch the next digit (1) from the dividend, attach it to 837 and continue: 8371 / 963

Step 6:
When dividing 8371 by 963, we get 8 with a remainder of 667.
Record the quotient 8 as the next digit in the result. 
Result so far: 748.0
Subtract 7704 from 8371 to get 667.
Bring next digit (8) of the dividend behind the 667 and repeat the process: 6678 / 963

On to step 7:
When dividing 6678 by 963, we get 6 with a remainder of 900.
Put 6 as the next digit of the answer. 
Result so far: 7486.0
Subtracting 5778 from 6678 leaves us with 900.
Take the next digit (8) from the dividend and append it to 900, then repeat: 9008 / 963

Step 8:
963 goes into 9008 9 times with a remainder of 341.
Put 9 as the next digit of the answer. 
Result so far: 74869.0
Subtracting 8667 from 9008 leaves us with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Let's proceed to step 9:
963 goes into 3410 3 times with a remainder of 521.
Write down 3 as next digit of the result. 
Result so far: 74869.3
The remainder is 521 after subtracting 2889 from 3410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

Advancing to step 10:
963 can be fit into 5210 5 times, resulting in a remainder of 395.
Record the quotient 5 as the next digit in the result. 
Result so far: 74869.35
The remainder is 395 after subtracting 4815 from 5210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Advancing to step 11:
963 can be fit into 3950 4 times, resulting in a remainder of 98.
Write down 4 as next digit of the result. 
Result so far: 74869.354
If we take 3852 away from 3950, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 12:
If we divide 980 by 963, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 74869.3541
If we take 963 away from 980, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 13:
963 can be fit into 170 0 times, resulting in a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 74869.3541
If we take 0 away from 170, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 14:
The number 963 fits into 1700 1 times, leaving a remainder of 737.
The next digit of our result is 1. 
Result so far: 74869.354101
If we subtract 963 from 1700, we get 737.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

Let's proceed to step 15:
963 goes into 7370 7 times with a remainder of 629.
The number 7 becomes the next digit in our result. 
Result so far: 74869.3541017
If we take 6741 away from 7370, we end up with 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

Step 16:
The number 963 fits into 6290 6 times, leaving a remainder of 512.
The next digit of our result is 6. 
Result so far: 74869.35410176
The remainder is 512 after subtracting 5778 from 6290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Our division results in 74869.35410176 with a remaining 5.12e-07.
