21231164 ÷ 963 
Let's see how many times 963 fits into 21231164.

Step 1:
The number 963 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 963

Moving on to step 2:
If we divide 21 by 963, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 963

Moving on to step 3:
If we divide 212 by 963, we get 0 and a remainder of 212.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 212 and we're left with 212.
Grab the next digit (3) from the dividend, add it to 212, then carry on: 2123 / 963

Moving on to step 4:
2123 divided by 963 is 2 with a remainder of 197.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1926 from 2123 and we're left with 197.
Fetch the next digit (1) from the dividend, attach it to 197 and continue: 1971 / 963

On to step 5:
963 can be fit into 1971 2 times, resulting in a remainder of 45.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 45 after subtracting 1926 from 1971.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 963

Step 6:
When dividing 451 by 963, we get 0 with a remainder of 451.
Write down 0 as next digit of the result. 
Result so far: 220.0
The remainder is 451 after subtracting 0 from 451.
Include the next digit (6) from the dividend after 451, then repeat: 4516 / 963

Step 7:
The number 963 fits into 4516 4 times, leaving a remainder of 664.
The number 4 becomes the next digit in our result. 
Result so far: 2204.0
If we subtract 3852 from 4516, we get 664.
Append the next digit (4) from the dividend to 664 and continue with: 6644 / 963

On to step 8:
6644 divided by 963 is 6 with a remainder of 866.
Record the quotient 6 as the next digit in the result. 
Result so far: 22046.0
Subtracting 5778 from 6644 leaves us with 866.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8660, and continue the process.

Going ahead to step 9:
8660 divided by 963 is 8 with a remainder of 956.
Record the quotient 8 as the next digit in the result. 
Result so far: 22046.8
If we subtract 7704 from 8660, we get 956.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9560, and continue the process.

Advancing to step 10:
When dividing 9560 by 963, we get 9 with a remainder of 893.
Put 9 as the next digit of the answer. 
Result so far: 22046.89
Subtract 8667 from 9560 to get 893.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8930, and continue the process.

Advancing to step 11:
963 can be fit into 8930 9 times, resulting in a remainder of 263.
Write down 9 as next digit of the result. 
Result so far: 22046.899
Subtracting 8667 from 8930 leaves us with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Our division results in 22046.899 with a remaining 0.0263.
