We divide 829747 by 21
Our goal is to divide 829747 by 21.

Moving on to step 1:
The number 21 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of 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

On to step 2:
The number 21 fits into 82 3 times, leaving a remainder of 19.
The next digit of our result is 3. 
Result so far: 3.0
If we take 63 away from 82, we end up with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 21

Moving on to step 3:
The number 21 fits into 199 9 times, leaving a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtracting 189 from 199 leaves us with 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 21

Advancing to step 4:
The number 21 fits into 107 5 times, leaving a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 395.0
Subtracting 105 from 107 leaves us with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 21

Let's proceed to step 5:
The number 21 fits into 24 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 3951.0
Subtracting 21 from 24 leaves us with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 21

Going ahead to step 6:
21 goes into 37 1 times with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 39511.0
If we subtract 21 from 37, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
The number 21 fits into 160 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 39511.7
Subtracting 147 from 160 leaves us 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.

Advancing to step 8:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 39511.76
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
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: 39511.761
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 10:
When dividing 190 by 21, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 39511.7619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 39511.7619
Subtract 0 from 10 to get 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 12:
If we divide 100 by 21, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 39511.761904
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
160 divided by 21 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 39511.7619047
If we subtract 147 from 160, we 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.

Let's proceed to step 14:
If we divide 130 by 21, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 39511.76190476
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 39511.76190476, with a leftover of 4e-09.
