We look at the division of 791041 by 21 
Let's see how many times 21 fits into 791041.

Moving on to step 1:
7 divided by 21 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 21

Moving on to step 2:
21 goes into 79 3 times with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 63 from 79 to get 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 21

Moving on to step 3:
21 goes into 161 7 times with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 37.0
The remainder is 14 after subtracting 147 from 161.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 21

Let's proceed to step 4:
140 divided by 21 is 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 376.0
If we take 126 away from 140, we end up with 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 21

Going ahead to step 5:
21 goes into 144 6 times with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 3766.0
Subtract 126 from 144 to get 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 21

Going ahead to step 6:
If we divide 181 by 21, we get 8 and a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 37668.0
Subtracting 168 from 181 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.

On to step 7:
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: 37668.6
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.

Let's proceed to step 8:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 37668.61
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
When dividing 190 by 21, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 37668.619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
If we divide 10 by 21, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 37668.619
Subtracting 0 from 10 leaves us with 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 11:
If we divide 100 by 21, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 37668.61904
If we take 84 away from 100, we end up 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.

Let's proceed to step 12:
When dividing 160 by 21, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 37668.619047
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.

On to step 13:
When dividing 130 by 21, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 37668.6190476
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 37668.61904761
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 37668.61904761 and a remainder of 1.9e-08.
