We're dividing 85126751 by 963 
The aim is to understand the frequency of 963 in 85126751.

Moving on to step 1:
8 divided by 963 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 963

Step 2:
963 can be fit into 85 0 times, resulting in a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Bring next digit (1) of the dividend behind the 85 and repeat the process: 851 / 963

Moving on to step 3:
The number 963 fits into 851 0 times, leaving a remainder of 851.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 851 leaves us with 851.
Bring next digit (2) of the dividend behind the 851 and repeat the process: 8512 / 963

Step 4:
When dividing 8512 by 963, we get 8 with a remainder of 808.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 7704 from 8512 and we're left with 808.
Take the next digit (6) from the dividend and append it to 808, then repeat: 8086 / 963

Moving on to step 5:
8086 divided by 963 is 8 with a remainder of 382.
Use 8 as the next digit of our solution. 
Result so far: 88.0
If we subtract 7704 from 8086, we get 382.
Fetch the next digit (7) from the dividend, attach it to 382 and continue: 3827 / 963

On to step 6:
The number 963 fits into 3827 3 times, leaving a remainder of 938.
Record the quotient 3 as the next digit in the result. 
Result so far: 883.0
If we subtract 2889 from 3827, we get 938.
Append the next digit (5) from the dividend to 938 and continue with: 9385 / 963

On to step 7:
963 goes into 9385 9 times with a remainder of 718.
The next digit of our result is 9. 
Result so far: 8839.0
The remainder is 718 after subtracting 8667 from 9385.
Take the next digit (1) from the dividend and append it to 718, then repeat: 7181 / 963

Step 8:
963 goes into 7181 7 times with a remainder of 440.
The number 7 becomes the next digit in our result. 
Result so far: 88397.0
If we take 6741 away from 7181, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 9:
The number 963 fits into 4400 4 times, leaving a remainder of 548.
Write down 4 as next digit of the result. 
Result so far: 88397.4
Subtract 3852 from 4400 to get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Moving on to step 10:
963 can be fit into 5480 5 times, resulting in a remainder of 665.
Write down 5 as next digit of the result. 
Result so far: 88397.45
If we take 4815 away from 5480, we end up with 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Step 11:
963 can be fit into 6650 6 times, resulting in a remainder of 872.
Record the quotient 6 as the next digit in the result. 
Result so far: 88397.456
If we subtract 5778 from 6650, we get 872.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8720, and continue the process.

On to step 12:
If we divide 8720 by 963, we get 9 and a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 88397.4569
If we subtract 8667 from 8720, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 13:
The number 963 fits into 530 0 times, leaving a remainder of 530.
The number 0 becomes the next digit in our result. 
Result so far: 88397.4569
Subtracting 0 from 530 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Going ahead to step 14:
963 goes into 5300 5 times with a remainder of 485.
Put 5 as the next digit of the answer. 
Result so far: 88397.456905
The remainder is 485 after subtracting 4815 from 5300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Step 15:
963 can be fit into 4850 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 88397.4569055
Subtracting 4815 from 4850 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 88397.4569055 and a remainder of 3.5e-07.
