We're dividing 83546109 by 963 
We want to figure out the number of times 83546109 can be divided by 963.

On to step 1:
If we divide 8 by 963, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 963

Let's proceed to step 2:
963 can be fit into 83 0 times, resulting in a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Append the next digit (5) from the dividend to 83 and continue with: 835 / 963

On to step 3:
The number 963 fits into 835 0 times, leaving a remainder of 835.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 835 after subtracting 0 from 835.
Grab the next digit (4) from the dividend, add it to 835, then carry on: 8354 / 963

Going ahead to step 4:
963 can be fit into 8354 8 times, resulting in a remainder of 650.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 7704 from 8354 to get 650.
Append the next digit (6) from the dividend to 650 and continue with: 6506 / 963

Going ahead to step 5:
When dividing 6506 by 963, we get 6 with a remainder of 728.
Write down 6 as next digit of the result. 
Result so far: 86.0
The remainder is 728 after subtracting 5778 from 6506.
Bring next digit (1) of the dividend behind the 728 and repeat the process: 7281 / 963

On to step 6:
7281 divided by 963 is 7 with a remainder of 540.
The next digit of our result is 7. 
Result so far: 867.0
If we subtract 6741 from 7281, we get 540.
Take the next digit (0) from the dividend and append it to 540, then repeat: 5400 / 963

Going ahead to step 7:
If we divide 5400 by 963, we get 5 and a remainder of 585.
Put 5 as the next digit of the answer. 
Result so far: 8675.0
Subtract 4815 from 5400 to get 585.
Take the next digit (9) from the dividend and append it to 585, then repeat: 5859 / 963

Let's proceed to step 8:
The number 963 fits into 5859 6 times, leaving a remainder of 81.
Record the quotient 6 as the next digit in the result. 
Result so far: 86756.0
Deduct 5778 from 5859 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 9:
If we divide 810 by 963, we get 0 and a remainder of 810.
The number 0 becomes the next digit in our result. 
Result so far: 86756.0
The remainder is 810 after subtracting 0 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

On to step 10:
When dividing 8100 by 963, we get 8 with a remainder of 396.
Write down 8 as next digit of the result. 
Result so far: 86756.08
Deduct 7704 from 8100 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Going ahead to step 11:
3960 divided by 963 is 4 with a remainder of 108.
Record the quotient 4 as the next digit in the result. 
Result so far: 86756.084
If we subtract 3852 from 3960, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 12:
If we divide 1080 by 963, we get 1 and a remainder of 117.
The number 1 becomes the next digit in our result. 
Result so far: 86756.0841
If we take 963 away from 1080, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 13:
1170 divided by 963 is 1 with a remainder of 207.
The next digit of our result is 1. 
Result so far: 86756.08411
If we subtract 963 from 1170, we get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

The final result is 86756.08411 with a remainder of 0.000207.
