Let's divide 826927 by 21
We want to figure out the number of times 826927 can be divided by 21.

Advancing to step 1:
21 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 21

On to step 2:
If we divide 82 by 21, we get 3 and a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 63 from 82, we get 19.
Include the next digit (6) from the dividend after 19, then repeat: 196 / 21

Advancing to step 3:
If we divide 196 by 21, we get 9 and a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Subtracting 189 from 196 leaves us with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 21

Advancing to step 4:
21 can be fit into 79 3 times, resulting in a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 393.0
Deduct 63 from 79 and we're left with 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 21

Advancing to step 5:
The number 21 fits into 162 7 times, leaving a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 3937.0
Subtracting 147 from 162 leaves us with 15.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 21

Going ahead to step 6:
When dividing 157 by 21, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 39377.0
Deduct 147 from 157 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 39377.4
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
160 divided by 21 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 39377.47
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 9:
When dividing 130 by 21, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 39377.476
Subtracting 126 from 130 leaves us 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.

Going ahead to step 10:
When dividing 40 by 21, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 39377.4761
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 11:
If we divide 190 by 21, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 39377.47619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 12:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 39377.47619
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
When dividing 100 by 21, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 39377.4761904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
160 divided by 21 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 39377.47619047
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 39377.47619047 with a remaining 1.3e-08.
