816075 divided by 21 
We want to divide 816075 by 21.

Let's proceed 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
If we take 0 away from 8, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 21

Step 2:
If we divide 81 by 21, we get 3 and a remainder of 18.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 18 after subtracting 63 from 81.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 21

Step 3:
The number 21 fits into 186 8 times, leaving a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we take 168 away from 186, we end up with 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 21

Step 4:
If we divide 180 by 21, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 388.0
If we take 168 away from 180, we end up with 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 21

Let's proceed to step 5:
When dividing 127 by 21, we get 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 3886.0
The remainder is 1 after subtracting 126 from 127.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 21

Advancing to step 6:
21 goes into 15 0 times with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 38860.0
If we subtract 0 from 15, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
The number 21 fits into 150 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 38860.7
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 38860.71
Subtract 21 from 30 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
When dividing 90 by 21, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 38860.714
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
21 goes into 60 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 38860.7142
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
21 goes into 180 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 38860.71428
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
21 can be fit into 120 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 38860.714285
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 38860.7142857
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
21 goes into 30 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 38860.71428571
Deduct 21 from 30 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The quotient of the division is 38860.71428571, and the remainder is 9e-09.
