We look at the division of 796385 by 21 
We're looking to find how many times 21 goes into 796385.

Let's proceed to step 1:
If we divide 7 by 21, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 21

Step 2:
The number 21 fits into 79 3 times, leaving a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 63 from 79 leaves us with 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 21

Going ahead to step 3:
21 can be fit into 166 7 times, resulting in a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Subtract 147 from 166 to get 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 21

Advancing to step 4:
When dividing 193 by 21, we get 9 with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 379.0
Subtract 189 from 193 to get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 21

Let's proceed to step 5:
48 divided by 21 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 3792.0
If we subtract 42 from 48, we get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 21

Let's proceed to step 6:
65 divided by 21 is 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 37923.0
Deduct 63 from 65 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.

Step 7:
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: 37923.0
If we take 0 away from 20, we end up 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.

Advancing to step 8:
If we divide 200 by 21, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 37923.09
Deduct 189 from 200 and we're left 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.

On to step 9:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 37923.095
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.

Advancing to step 10:
When dividing 50 by 21, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 37923.0952
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.

Going ahead to step 11:
When dividing 80 by 21, we get 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 37923.09523
Subtract 63 from 80 to 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.

Moving on to step 12:
21 goes into 170 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 37923.095238
If we subtract 168 from 170, we get 2.
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 13:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 37923.095238
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 14:
If we divide 200 by 21, we get 9 and a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 37923.09523809
Subtract 189 from 200 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.

The final result is 37923.09523809 with a remainder of 1.1e-08.
