We divide 81941717 by 663
We want to figure out the number of times 81941717 can be divided by 663.

On to step 1:
8 divided by 663 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 663

Moving on to step 2:
When dividing 81 by 663, we get 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (9) from the dividend, attach it to 81 and continue: 819 / 663

Advancing to step 3:
When dividing 819 by 663, we get 1 with a remainder of 156.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 663 from 819 leaves us with 156.
Append the next digit (4) from the dividend to 156 and continue with: 1564 / 663

Step 4:
663 can be fit into 1564 2 times, resulting in a remainder of 238.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 1326 from 1564 to get 238.
Bring next digit (1) of the dividend behind the 238 and repeat the process: 2381 / 663

Advancing to step 5:
663 can be fit into 2381 3 times, resulting in a remainder of 392.
Put 3 as the next digit of the answer. 
Result so far: 123.0
If we subtract 1989 from 2381, we get 392.
Bring next digit (7) of the dividend behind the 392 and repeat the process: 3927 / 663

Going ahead to step 6:
If we divide 3927 by 663, we get 5 and a remainder of 612.
Put 5 as the next digit of the answer. 
Result so far: 1235.0
Subtract 3315 from 3927 to get 612.
Fetch the next digit (1) from the dividend, attach it to 612 and continue: 6121 / 663

Step 7:
6121 divided by 663 is 9 with a remainder of 154.
Put 9 as the next digit of the answer. 
Result so far: 12359.0
Subtract 5967 from 6121 to get 154.
Append the next digit (7) from the dividend to 154 and continue with: 1547 / 663

Moving on to step 8:
When dividing 1547 by 663, we get 2 with a remainder of 221.
Record the quotient 2 as the next digit in the result. 
Result so far: 123592.0
Subtracting 1326 from 1547 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Going ahead to step 9:
663 can be fit into 2210 3 times, resulting in a remainder of 221.
Put 3 as the next digit of the answer. 
Result so far: 123592.3
Deduct 1989 from 2210 and we're left with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Moving on to step 10:
The number 663 fits into 2210 3 times, leaving a remainder of 221.
Put 3 as the next digit of the answer. 
Result so far: 123592.33
If we take 1989 away from 2210, we end up with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

The final result is 123592.33 with a remainder of 0.221.
