715786 divided by 20 
We're looking to find how many times 20 goes into 715786.

Going ahead to step 1:
20 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 20

Advancing to step 2:
If we divide 71 by 20, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 60 from 71, we get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 20

Moving on to step 3:
When dividing 115 by 20, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 35.0
Subtract 100 from 115 to get 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 20

On to step 4:
157 divided by 20 is 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 357.0
Subtracting 140 from 157 leaves us with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 20

Let's proceed to step 5:
20 goes into 178 8 times with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 3578.0
Subtract 160 from 178 to get 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 20

Advancing to step 6:
The number 20 fits into 186 9 times, leaving a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 35789.0
If we take 180 away from 186, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
If we divide 60 by 20, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 35789.3
If we take 60 away from 60, 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.

Moving on to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 35789.3
If we subtract 0 from 0, 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 9:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 35789.3
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.

The final result is 35789.3 with a remainder of 0.0.
