926779 divided by 21 
We want to figure out the number of times 926779 can be divided by 21.

On to step 1:
21 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 21

Step 2:
21 goes into 92 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 8 after subtracting 84 from 92.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 21

Moving on to step 3:
If we divide 86 by 21, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 44.0
If we subtract 84 from 86, we get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 21

Moving on to step 4:
If we divide 27 by 21, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 441.0
If we subtract 21 from 27, we get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 21

Let's proceed to step 5:
67 divided by 21 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 4413.0
Subtracting 63 from 67 leaves us with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 21

Going ahead to step 6:
If we divide 49 by 21, we get 2 and a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 44132.0
Subtract 42 from 49 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
When dividing 70 by 21, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 44132.3
If we take 63 away from 70, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
If we divide 70 by 21, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 44132.33
If we take 63 away from 70, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 44132.33 and a remainder of 0.007.
