We divide 789520 by 20
We want to figure out the number of times 789520 can be divided by 20.

Step 1:
7 divided by 20 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 20

Let's proceed to step 2:
The number 20 fits into 78 3 times, leaving a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 60 from 78 leaves us with 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 20

On to step 3:
When dividing 189 by 20, we get 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we take 180 away from 189, we end up with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 20

Advancing to step 4:
95 divided by 20 is 4 with a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 394.0
If we take 80 away from 95, we end up with 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 20

Going ahead to step 5:
If we divide 152 by 20, we get 7 and a remainder of 12.
The next digit of our result is 7. 
Result so far: 3947.0
The remainder is 12 after subtracting 140 from 152.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 20

Going ahead to step 6:
120 divided by 20 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 39476.0
If we subtract 120 from 120, we get 0.
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 7:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 39476.0
Deduct 0 from 0 and we're left 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.

Moving on to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 39476.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 39476.0 and a remainder of 0.0.
