We're dividing 11127790 by 21 
We're looking to find how many times 21 goes into 11127790.

Advancing to step 1:
21 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 21

On to step 2:
21 can be fit into 11 0 times, resulting in a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 21

On to step 3:
If we divide 111 by 21, we get 5 and a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 105 from 111 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 21

Going ahead to step 4:
The number 21 fits into 62 2 times, leaving a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 52.0
Subtract 42 from 62 to get 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 21

Going ahead to step 5:
The number 21 fits into 207 9 times, leaving a remainder of 18.
The next digit of our result is 9. 
Result so far: 529.0
If we subtract 189 from 207, we get 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 21

Step 6:
If we divide 187 by 21, we get 8 and a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 5298.0
If we take 168 away from 187, we end up with 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 21

Advancing to step 7:
21 goes into 199 9 times with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 52989.0
The remainder is 10 after subtracting 189 from 199.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 21

Moving on to step 8:
When dividing 100 by 21, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 529894.0
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 529894.7
Deduct 147 from 160 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 10:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 529894.76
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 529894.761
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 12:
190 divided by 21 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 529894.7619
Deduct 189 from 190 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 13:
10 divided by 21 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 529894.7619
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
100 divided by 21 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 529894.761904
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 15:
160 divided by 21 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 529894.7619047
Deduct 147 from 160 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 16:
When dividing 130 by 21, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 529894.76190476
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 529894.76190476 with a remainder of 4e-09.
