829196 ÷ 21 
Let's see how many times 21 fits into 829196.

On to step 1:
8 divided by 21 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 21

Let's proceed to step 2:
21 can be fit into 82 3 times, resulting in a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 63 from 82 to get 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 21

On to step 3:
21 can be fit into 199 9 times, resulting in 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.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 21

Moving on to step 4:
101 divided by 21 is 4 with a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 394.0
Subtracting 84 from 101 leaves us with 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 21

Going ahead to step 5:
The number 21 fits into 179 8 times, leaving a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 3948.0
The remainder is 11 after subtracting 168 from 179.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 21

Moving on to step 6:
21 goes into 116 5 times with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 39485.0
Subtract 105 from 116 to 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.

Moving on to step 7:
If we divide 110 by 21, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 39485.5
If we subtract 105 from 110, we 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 8:
50 divided by 21 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 39485.52
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.

Let's proceed to step 9:
80 divided by 21 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 39485.523
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.

Advancing to step 10:
When dividing 170 by 21, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 39485.5238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 39485.5238
Subtracting 0 from 20 leaves us 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.

Step 12:
If we divide 200 by 21, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 39485.523809
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 13:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 39485.5238095
Deduct 105 from 110 and we're left 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.

On to step 14:
50 divided by 21 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 39485.52380952
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.

In conclusion, the division gives 39485.52380952 with a balance of 8e-09.
