We divide 416531 by 21
Our goal is to divide 416531 by 21.

On to step 1:
21 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 21

On to step 2:
21 can be fit into 41 1 times, resulting in a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 21 from 41 to get 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 21

Advancing to step 3:
21 goes into 206 9 times with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 189 from 206 and we're left with 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 21

On to step 4:
If we divide 175 by 21, we get 8 and a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 198.0
Deduct 168 from 175 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 21

Advancing to step 5:
21 can be fit into 73 3 times, resulting in a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 1983.0
If we take 63 away from 73, we end up with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 21

Let's proceed to step 6:
21 goes into 101 4 times with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 19834.0
Subtracting 84 from 101 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
170 divided by 21 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 19834.8
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
If we divide 20 by 21, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 19834.8
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
21 goes into 200 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 19834.809
Deduct 189 from 200 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 10:
If we divide 110 by 21, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 19834.8095
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
50 divided by 21 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 19834.80952
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 19834.809523
Subtracting 63 from 80 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 13:
21 goes into 170 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 19834.8095238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
21 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 19834.8095238
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 19834.8095238 with a remaining 2e-08.
