We're dividing 91151994 by 963 
We want to figure out the number of times 91151994 can be divided by 963.

Going ahead to step 1:
When dividing 9 by 963, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 963

Moving on to step 2:
963 can be fit into 91 0 times, resulting in a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Grab the next digit (1) from the dividend, add it to 91, then carry on: 911 / 963

Let's proceed to step 3:
963 can be fit into 911 0 times, resulting in a remainder of 911.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 911, we end up with 911.
Take the next digit (5) from the dividend and append it to 911, then repeat: 9115 / 963

Going ahead to step 4:
The number 963 fits into 9115 9 times, leaving a remainder of 448.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 8667 from 9115, we get 448.
Fetch the next digit (1) from the dividend, attach it to 448 and continue: 4481 / 963

Step 5:
4481 divided by 963 is 4 with a remainder of 629.
Write down 4 as next digit of the result. 
Result so far: 94.0
Deduct 3852 from 4481 and we're left with 629.
Append the next digit (9) from the dividend to 629 and continue with: 6299 / 963

Going ahead to step 6:
963 can be fit into 6299 6 times, resulting in a remainder of 521.
The number 6 becomes the next digit in our result. 
Result so far: 946.0
Subtracting 5778 from 6299 leaves us with 521.
Fetch the next digit (9) from the dividend, attach it to 521 and continue: 5219 / 963

Advancing to step 7:
963 can be fit into 5219 5 times, resulting in a remainder of 404.
Write down 5 as next digit of the result. 
Result so far: 9465.0
The remainder is 404 after subtracting 4815 from 5219.
Take the next digit (4) from the dividend and append it to 404, then repeat: 4044 / 963

Step 8:
4044 divided by 963 is 4 with a remainder of 192.
Use 4 as the next digit of our solution. 
Result so far: 94654.0
Deduct 3852 from 4044 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 9:
The number 963 fits into 1920 1 times, leaving a remainder of 957.
The next digit of our result is 1. 
Result so far: 94654.1
Deduct 963 from 1920 and we're left with 957.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9570, and continue the process.

Going ahead to step 10:
963 goes into 9570 9 times with a remainder of 903.
Use 9 as the next digit of our solution. 
Result so far: 94654.19
Subtract 8667 from 9570 to get 903.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9030, and continue the process.

On to step 11:
When dividing 9030 by 963, we get 9 with a remainder of 363.
Put 9 as the next digit of the answer. 
Result so far: 94654.199
Deduct 8667 from 9030 and we're left with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

The final result is 94654.199 with a remainder of 0.0363.
