We're dividing 772115 by 20 
Let's see how many times 20 fits into 772115.

On to step 1:
The number 20 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 20

Going ahead to step 2:
When dividing 77 by 20, we get 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 60 away from 77, we end up with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 20

Step 3:
20 can be fit into 172 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 38.0
If we take 160 away from 172, we end up with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 20

Let's proceed to step 4:
The number 20 fits into 121 6 times, leaving a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 386.0
If we take 120 away from 121, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 20

Moving on to step 5:
If we divide 11 by 20, we get 0 and a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 3860.0
Subtract 0 from 11 to get 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 20

Moving on to step 6:
The number 20 fits into 115 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 38605.0
Deduct 100 from 115 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
The number 20 fits into 150 7 times, leaving a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 38605.7
If we subtract 140 from 150, we get 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 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 38605.75
Deduct 100 from 100 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.

Step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 38605.75
Subtract 0 from 0 to 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 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 38605.75
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.

In conclusion, the division gives 38605.75 with a balance of 0.0.
