21318561 divided by 962 
We want to figure out the number of times 21318561 can be divided by 962.

On to step 1:
2 divided by 962 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 962

Going ahead to step 2:
21 divided by 962 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 962

Moving on to step 3:
962 can be fit into 213 0 times, resulting in a remainder of 213.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 213, we end up with 213.
Take the next digit (1) from the dividend and append it to 213, then repeat: 2131 / 962

Going ahead to step 4:
2131 divided by 962 is 2 with a remainder of 207.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1924 from 2131 to get 207.
Bring next digit (8) of the dividend behind the 207 and repeat the process: 2078 / 962

Advancing to step 5:
962 goes into 2078 2 times with a remainder of 154.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 1924 from 2078, we get 154.
Take the next digit (5) from the dividend and append it to 154, then repeat: 1545 / 962

Going ahead to step 6:
962 goes into 1545 1 times with a remainder of 583.
Use 1 as the next digit of our solution. 
Result so far: 221.0
If we take 962 away from 1545, we end up with 583.
Take the next digit (6) from the dividend and append it to 583, then repeat: 5836 / 962

Moving on to step 7:
962 can be fit into 5836 6 times, resulting in a remainder of 64.
The next digit of our result is 6. 
Result so far: 2216.0
Deduct 5772 from 5836 and we're left with 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 962

On to step 8:
When dividing 641 by 962, we get 0 with a remainder of 641.
Use 0 as the next digit of our solution. 
Result so far: 22160.0
If we take 0 away from 641, we end up with 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

On to step 9:
6410 divided by 962 is 6 with a remainder of 638.
Write down 6 as next digit of the result. 
Result so far: 22160.6
Deduct 5772 from 6410 and we're left with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Advancing to step 10:
The number 962 fits into 6380 6 times, leaving a remainder of 608.
Put 6 as the next digit of the answer. 
Result so far: 22160.66
Deduct 5772 from 6380 and we're left with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

The final outcome is 22160.66, with a leftover of 0.608.
