We look at the division of 21114166 by 9 
Our goal is to divide 21114166 by 9.

On to step 1:
2 divided by 9 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 9

Going ahead to step 2:
If we divide 21 by 9, we get 2 and a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 18 from 21 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 9

Moving on to step 3:
The number 9 fits into 31 3 times, leaving a remainder of 4.
The next digit of our result is 3. 
Result so far: 23.0
If we take 27 away from 31, we end up with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 9

On to step 4:
9 goes into 41 4 times with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 234.0
Subtracting 36 from 41 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 9

On to step 5:
When dividing 54 by 9, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 2346.0
Subtract 54 from 54 to get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 9

Going ahead to step 6:
When dividing 1 by 9, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 23460.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 9

Step 7:
16 divided by 9 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 234601.0
If we subtract 9 from 16, we get 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 9

On to step 8:
When dividing 76 by 9, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 2346018.0
If we subtract 72 from 76, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
The number 9 fits into 40 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 2346018.4
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
The number 9 fits into 40 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 2346018.44
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 2346018.44, and the remainder is 0.004.
