We're dividing 21120412 by 918 
We want to divide 21120412 by 918.

Moving on to step 1:
When dividing 2 by 918, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 918

Step 2:
The number 918 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 918

On to step 3:
918 can be fit into 211 0 times, resulting in a remainder of 211.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 211, we end up with 211.
Include the next digit (2) from the dividend after 211, then repeat: 2112 / 918

Advancing to step 4:
918 can be fit into 2112 2 times, resulting in a remainder of 276.
The next digit of our result is 2. 
Result so far: 2.0
If we take 1836 away from 2112, we end up with 276.
Fetch the next digit (0) from the dividend, attach it to 276 and continue: 2760 / 918

Moving on to step 5:
2760 divided by 918 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 23.0
The remainder is 6 after subtracting 2754 from 2760.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 918

Going ahead to step 6:
If we divide 64 by 918, we get 0 and a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 230.0
Subtracting 0 from 64 leaves us with 64.
Fetch the next digit (1) from the dividend, attach it to 64 and continue: 641 / 918

Step 7:
918 goes into 641 0 times with a remainder of 641.
The number 0 becomes the next digit in our result. 
Result so far: 2300.0
Subtract 0 from 641 to get 641.
Fetch the next digit (2) from the dividend, attach it to 641 and continue: 6412 / 918

Moving on to step 8:
The number 918 fits into 6412 6 times, leaving a remainder of 904.
The next digit of our result is 6. 
Result so far: 23006.0
Subtract 5508 from 6412 to get 904.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9040, and continue the process.

Moving on to step 9:
When dividing 9040 by 918, we get 9 with a remainder of 778.
Use 9 as the next digit of our solution. 
Result so far: 23006.9
Deduct 8262 from 9040 and we're left with 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

Going ahead to step 10:
918 can be fit into 7780 8 times, resulting in a remainder of 436.
Write down 8 as next digit of the result. 
Result so far: 23006.98
Subtract 7344 from 7780 to get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Step 11:
If we divide 4360 by 918, we get 4 and a remainder of 688.
Write down 4 as next digit of the result. 
Result so far: 23006.984
If we subtract 3672 from 4360, we get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Moving on to step 12:
If we divide 6880 by 918, we get 7 and a remainder of 454.
Use 7 as the next digit of our solution. 
Result so far: 23006.9847
If we subtract 6426 from 6880, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Advancing to step 13:
If we divide 4540 by 918, we get 4 and a remainder of 868.
Write down 4 as next digit of the result. 
Result so far: 23006.98474
If we take 3672 away from 4540, we end up with 868.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8680, and continue the process.

Going ahead to step 14:
When dividing 8680 by 918, we get 9 with a remainder of 418.
Use 9 as the next digit of our solution. 
Result so far: 23006.984749
If we subtract 8262 from 8680, we get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Step 15:
When dividing 4180 by 918, we get 4 with a remainder of 508.
The number 4 becomes the next digit in our result. 
Result so far: 23006.9847494
Deduct 3672 from 4180 and we're left with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

On to step 16:
If we divide 5080 by 918, we get 5 and a remainder of 490.
Use 5 as the next digit of our solution. 
Result so far: 23006.98474945
Subtracting 4590 from 5080 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

The final result is 23006.98474945 with a remainder of 4.9e-07.
