We look at the division of 224988 by 21 
We want to divide 224988 by 21.

On to step 1:
2 divided by 21 is 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.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 21

Let's proceed to step 2:
If we divide 22 by 21, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 21 from 22 leaves us with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 21

Let's proceed to step 3:
When dividing 14 by 21, we get 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 14 and we're left with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 21

On to step 4:
21 goes into 149 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 107.0
Subtracting 147 from 149 leaves us with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 21

Moving on to step 5:
The number 21 fits into 28 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1071.0
The remainder is 7 after subtracting 21 from 28.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 21

Advancing to step 6:
21 can be fit into 78 3 times, resulting in a remainder of 15.
The next digit of our result is 3. 
Result so far: 10713.0
If we take 63 away from 78, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
21 goes into 150 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 10713.7
If we take 147 away from 150, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
30 divided by 21 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 10713.71
The remainder is 9 after subtracting 21 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
If we divide 90 by 21, we get 4 and a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 10713.714
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
The number 21 fits into 60 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 10713.7142
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 11:
If we divide 180 by 21, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 10713.71428
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
The number 21 fits into 120 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 10713.714285
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
21 can be fit into 150 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 10713.7142857
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
30 divided by 21 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 10713.71428571
The remainder is 9 after subtracting 21 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 10713.71428571, with a leftover of 9e-09.
