We're dividing 913879 by 20 
We want to figure out the number of times 913879 can be divided by 20.

Moving on to step 1:
When dividing 9 by 20, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 20

Step 2:
The number 20 fits into 91 4 times, leaving a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 80 from 91, we get 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 20

On to step 3:
The number 20 fits into 113 5 times, leaving a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we take 100 away from 113, we end up with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 20

Step 4:
20 can be fit into 138 6 times, resulting in a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 456.0
The remainder is 18 after subtracting 120 from 138.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 20

On to step 5:
20 can be fit into 187 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 4569.0
Deduct 180 from 187 and we're left with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 20

Advancing to step 6:
20 can be fit into 79 3 times, resulting in a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 45693.0
Subtract 60 from 79 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 7:
The number 20 fits into 190 9 times, leaving a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 45693.9
If we take 180 away from 190, we end up 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.

Moving on to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 45693.95
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 45693.95
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 45693.95
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 45693.95 with a remaining 0.0.
