828695 divided by 21 
We're looking to find how many times 21 goes into 828695.

Let's proceed to step 1:
21 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 21

Advancing to step 2:
The number 21 fits into 82 3 times, leaving a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 63 from 82 to get 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 21

Advancing to step 3:
If we divide 198 by 21, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
The remainder is 9 after subtracting 189 from 198.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 21

Step 4:
21 can be fit into 96 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 394.0
Subtracting 84 from 96 leaves us with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 21

Let's proceed to step 5:
The number 21 fits into 129 6 times, leaving a remainder of 3.
The next digit of our result is 6. 
Result so far: 3946.0
The remainder is 3 after subtracting 126 from 129.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 21

Going ahead to step 6:
21 goes into 35 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 39461.0
Deduct 21 from 35 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
21 goes into 140 6 times with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 39461.6
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
When dividing 140 by 21, we get 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 39461.66
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 39461.66 with a remainder of 0.014.
