We divide 99539101 by 963
We want to divide 99539101 by 963.

Going ahead to step 1:
When dividing 9 by 963, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 963

Step 2:
963 goes into 99 0 times with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Include the next digit (5) from the dividend after 99, then repeat: 995 / 963

Let's proceed to step 3:
963 goes into 995 1 times with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 963 from 995 to get 32.
Grab the next digit (3) from the dividend, add it to 32, then carry on: 323 / 963

On to step 4:
The number 963 fits into 323 0 times, leaving a remainder of 323.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 323 after subtracting 0 from 323.
Grab the next digit (9) from the dividend, add it to 323, then carry on: 3239 / 963

Advancing to step 5:
963 can be fit into 3239 3 times, resulting in a remainder of 350.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
If we subtract 2889 from 3239, we get 350.
Grab the next digit (1) from the dividend, add it to 350, then carry on: 3501 / 963

Step 6:
When dividing 3501 by 963, we get 3 with a remainder of 612.
The number 3 becomes the next digit in our result. 
Result so far: 1033.0
If we subtract 2889 from 3501, we get 612.
Grab the next digit (0) from the dividend, add it to 612, then carry on: 6120 / 963

Let's proceed to step 7:
When dividing 6120 by 963, we get 6 with a remainder of 342.
Put 6 as the next digit of the answer. 
Result so far: 10336.0
If we subtract 5778 from 6120, we get 342.
Bring next digit (1) of the dividend behind the 342 and repeat the process: 3421 / 963

Step 8:
963 goes into 3421 3 times with a remainder of 532.
The number 3 becomes the next digit in our result. 
Result so far: 103363.0
The remainder is 532 after subtracting 2889 from 3421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Let's proceed to step 9:
The number 963 fits into 5320 5 times, leaving a remainder of 505.
Use 5 as the next digit of our solution. 
Result so far: 103363.5
Subtract 4815 from 5320 to get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Step 10:
When dividing 5050 by 963, we get 5 with a remainder of 235.
Record the quotient 5 as the next digit in the result. 
Result so far: 103363.55
Subtract 4815 from 5050 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

After the division, we end up with 103363.55 and a remainder of 0.235.
