Let's divide 561305 by 21
Our goal is to divide 561305 by 21.

On to step 1:
5 divided by 21 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 21

Advancing to step 2:
21 goes into 56 2 times with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 14 after subtracting 42 from 56.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 21

Going ahead to step 3:
21 goes into 141 6 times with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Deduct 126 from 141 and we're left with 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 21

Let's proceed to step 4:
21 goes into 153 7 times with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 267.0
Subtract 147 from 153 to get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 21

On to step 5:
21 goes into 60 2 times with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 2672.0
The remainder is 18 after subtracting 42 from 60.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 21

Moving on to step 6:
When dividing 185 by 21, we get 8 with a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 26728.0
The remainder is 17 after subtracting 168 from 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
21 goes into 170 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 26728.8
Deduct 168 from 170 and we're left with 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 8:
21 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 26728.8
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
200 divided by 21 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 26728.809
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
The number 21 fits into 110 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 26728.8095
Subtract 105 from 110 to 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.

Going ahead to step 11:
If we divide 50 by 21, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 26728.80952
If we take 42 away from 50, we end up with 8.
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:
The number 21 fits into 80 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 26728.809523
Deduct 63 from 80 and we're left 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:
If we divide 170 by 21, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 26728.8095238
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
20 divided by 21 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 26728.8095238
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.

The final outcome is 26728.8095238, with a leftover of 2e-08.
