Let's divide 563707 by 21
Let's see how many times 21 fits into 563707.

Advancing to step 1:
5 divided by 21 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 21

Advancing to step 2:
56 divided by 21 is 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 42 from 56 to get 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 21

Step 3:
143 divided by 21 is 6 with a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 26.0
The remainder is 17 after subtracting 126 from 143.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 21

On to step 4:
21 goes into 177 8 times with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 268.0
The remainder is 9 after subtracting 168 from 177.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 21

Let's proceed to step 5:
21 can be fit into 90 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 2684.0
Subtracting 84 from 90 leaves us with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 21

Advancing to step 6:
If we divide 67 by 21, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 26843.0
Deduct 63 from 67 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
If we divide 40 by 21, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 26843.1
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 26843.19
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
If we divide 10 by 21, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 26843.19
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
21 goes into 100 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 26843.1904
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
21 can be fit into 160 7 times, resulting in a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 26843.19047
Deduct 147 from 160 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 12:
When dividing 130 by 21, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 26843.190476
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 26843.1904761
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 14:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 26843.19047619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 26843.19047619 with a remaining 1e-09.
