We look at the division of 465543 by 21 
Let's see how many times 21 fits into 465543.

Let's proceed to step 1:
The number 21 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 21

On to step 2:
21 can be fit into 46 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 42 from 46 leaves us with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 21

Let's proceed to step 3:
21 goes into 45 2 times with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we subtract 42 from 45, we get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 21

Let's proceed to step 4:
35 divided by 21 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 221.0
The remainder is 14 after subtracting 21 from 35.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 21

On to step 5:
144 divided by 21 is 6 with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 2216.0
If we subtract 126 from 144, we get 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 21

On to step 6:
21 can be fit into 183 8 times, resulting in a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 22168.0
Subtracting 168 from 183 leaves us 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.

Moving on to step 7:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 22168.7
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.

Advancing to step 8:
When dividing 30 by 21, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 22168.71
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.

Advancing to step 9:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 22168.714
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
When dividing 60 by 21, we get 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 22168.7142
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.

Going ahead to step 11:
180 divided by 21 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 22168.71428
Subtract 168 from 180 to 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 12:
21 goes into 120 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 22168.714285
If we take 105 away from 120, 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.

Moving on to step 13:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 22168.7142857
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.

Let's proceed to step 14:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 22168.71428571
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.

Our division results in 22168.71428571 with a remaining 9e-09.
