791062 ÷ 21 
Let's see how many times 21 fits into 791062.

Moving on to step 1:
When dividing 7 by 21, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 21

Let's proceed to step 2:
When dividing 79 by 21, we get 3 with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 16 after subtracting 63 from 79.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 21

Moving on to step 3:
21 goes into 161 7 times with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we subtract 147 from 161, we get 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 21

Moving on to step 4:
140 divided by 21 is 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 376.0
If we subtract 126 from 140, we get 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 21

Moving on to step 5:
If we divide 146 by 21, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 3766.0
If we subtract 126 from 146, we get 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 21

Advancing to step 6:
202 divided by 21 is 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 37669.0
Subtracting 189 from 202 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.

Moving on to step 7:
When dividing 130 by 21, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 37669.6
If we take 126 away from 130, we end up 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.

On to step 8:
21 goes into 40 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 37669.61
The remainder is 19 after subtracting 21 from 40.
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:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 37669.619
Deduct 189 from 190 and we're left with 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 10:
21 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 37669.619
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.

Let's proceed to step 11:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 37669.61904
If we subtract 84 from 100, 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.

Going ahead 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: 37669.619047
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.

Let's proceed to step 13:
21 can be fit into 130 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 37669.6190476
Deduct 126 from 130 and we're left 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.

Let's proceed to step 14:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 37669.61904761
Subtracting 21 from 40 leaves us 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.

The final outcome is 37669.61904761, with a leftover of 1.9e-08.
