We divide 829127 by 21
We're looking to find how many times 21 goes into 829127.

On 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
The remainder is 8 after subtracting 0 from 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 21

Let's proceed to step 2:
21 can be fit into 82 3 times, resulting in a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 63 away from 82, we end up with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 21

On to step 3:
When dividing 199 by 21, we get 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we take 189 away from 199, we end up with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 21

Moving on to step 4:
21 goes into 101 4 times with a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 394.0
If we subtract 84 from 101, we get 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 21

On to step 5:
The number 21 fits into 172 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 3948.0
If we subtract 168 from 172, we get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 21

On to step 6:
47 divided by 21 is 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 39482.0
Subtract 42 from 47 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.

Moving on to step 7:
When dividing 50 by 21, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 39482.2
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 39482.23
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
170 divided by 21 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 39482.238
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 10:
When dividing 20 by 21, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 39482.238
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
If we divide 200 by 21, we get 9 and a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 39482.23809
If we take 189 away from 200, we end up 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.

Moving on to step 12:
If we divide 110 by 21, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 39482.238095
Subtracting 105 from 110 leaves us with 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 13:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 39482.2380952
If we subtract 42 from 50, we get 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 14:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 39482.23809523
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The quotient of the division is 39482.23809523, and the remainder is 1.7e-08.
