Let's divide 21065579 by 111
We want to divide 21065579 by 111.

Let's proceed to step 1:
111 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 111

Advancing to step 2:
21 divided by 111 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 111

Let's proceed to step 3:
111 goes into 210 1 times with a remainder of 99.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 99 after subtracting 111 from 210.
Take the next digit (6) from the dividend and append it to 99, then repeat: 996 / 111

Let's proceed to step 4:
If we divide 996 by 111, we get 8 and a remainder of 108.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 888 from 996 to get 108.
Grab the next digit (5) from the dividend, add it to 108, then carry on: 1085 / 111

Let's proceed to step 5:
The number 111 fits into 1085 9 times, leaving a remainder of 86.
Write down 9 as next digit of the result. 
Result so far: 189.0
If we subtract 999 from 1085, we get 86.
Grab the next digit (5) from the dividend, add it to 86, then carry on: 865 / 111

On to step 6:
If we divide 865 by 111, we get 7 and a remainder of 88.
The number 7 becomes the next digit in our result. 
Result so far: 1897.0
If we subtract 777 from 865, we get 88.
Fetch the next digit (7) from the dividend, attach it to 88 and continue: 887 / 111

Let's proceed to step 7:
111 goes into 887 7 times with a remainder of 110.
Put 7 as the next digit of the answer. 
Result so far: 18977.0
Subtract 777 from 887 to get 110.
Bring next digit (9) of the dividend behind the 110 and repeat the process: 1109 / 111

On to step 8:
The number 111 fits into 1109 9 times, leaving a remainder of 110.
The next digit of our result is 9. 
Result so far: 189779.0
If we subtract 999 from 1109, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 9:
111 can be fit into 1100 9 times, resulting in a remainder of 101.
Write down 9 as next digit of the result. 
Result so far: 189779.9
Deduct 999 from 1100 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 10:
The number 111 fits into 1010 9 times, leaving a remainder of 11.
The next digit of our result is 9. 
Result so far: 189779.99
Subtract 999 from 1010 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 189779.99 with a remainder of 0.011.
