We're dividing 914427 by 21 
Let's see how many times 21 fits into 914427.

Going ahead to step 1:
21 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 21

Step 2:
The number 21 fits into 91 4 times, leaving a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 7 after subtracting 84 from 91.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 21

Going ahead to step 3:
When dividing 74 by 21, we get 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtract 63 from 74 to get 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 21

Moving on to step 4:
If we divide 114 by 21, we get 5 and a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 435.0
If we subtract 105 from 114, we get 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 21

Step 5:
If we divide 92 by 21, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4354.0
If we take 84 away from 92, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 21

Moving on to step 6:
21 can be fit into 87 4 times, resulting in a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 43544.0
If we subtract 84 from 87, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
21 goes into 30 1 times with a remainder of 9.
The next digit of our result is 1. 
Result so far: 43544.1
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.

On to step 8:
If we divide 90 by 21, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 43544.14
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.

On to step 9:
21 can be fit into 60 2 times, resulting in a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 43544.142
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
21 can be fit into 180 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 43544.1428
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
120 divided by 21 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 43544.14285
The remainder is 15 after subtracting 105 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
150 divided by 21 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 43544.142857
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 13:
30 divided by 21 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 43544.1428571
If we take 21 away from 30, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 14:
When dividing 90 by 21, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 43544.14285714
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.

The quotient of the division is 43544.14285714, and the remainder is 6e-09.
