Let's divide 830727 by 21
We want to divide 830727 by 21.

On to step 1:
8 divided by 21 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 21

Going ahead to step 2:
If we divide 83 by 21, we get 3 and a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 63 from 83, we get 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 21

Moving on to step 3:
If we divide 200 by 21, we get 9 and a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we subtract 189 from 200, we get 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 21

Moving on to step 4:
21 can be fit into 117 5 times, resulting in a remainder of 12.
The next digit of our result is 5. 
Result so far: 395.0
The remainder is 12 after subtracting 105 from 117.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 21

Advancing to step 5:
122 divided by 21 is 5 with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 3955.0
Subtract 105 from 122 to get 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 21

Advancing to step 6:
21 can be fit into 177 8 times, resulting in a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 39558.0
The remainder is 9 after subtracting 168 from 177.
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 7:
90 divided by 21 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 39558.4
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 8:
When dividing 60 by 21, we get 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 39558.42
If we subtract 42 from 60, we get 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 9:
21 goes into 180 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 39558.428
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
When dividing 120 by 21, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 39558.4285
If we subtract 105 from 120, we get 15.
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 11:
If we divide 150 by 21, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 39558.42857
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.

On to step 12:
21 can be fit into 30 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 39558.428571
Subtracting 21 from 30 leaves us 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.

Going ahead to step 13:
When dividing 90 by 21, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 39558.4285714
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
The number 21 fits into 60 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 39558.42857142
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 39558.42857142 with a remainder of 1.8e-08.
