We're dividing 777131 by 20 
Let's see how many times 20 fits into 777131.

Advancing to step 1:
7 divided by 20 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 20

Advancing to step 2:
20 goes into 77 3 times 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.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 20

Going ahead to step 3:
20 can be fit into 177 8 times, resulting in a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we take 160 away from 177, we end up with 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 20

Advancing to step 4:
If we divide 171 by 20, we get 8 and a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 388.0
Subtracting 160 from 171 leaves us with 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 20

Going ahead to step 5:
20 can be fit into 113 5 times, resulting in a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 3885.0
If we take 100 away from 113, we end up with 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 20

Let's proceed to step 6:
If we divide 131 by 20, we get 6 and a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 38856.0
The remainder is 11 after subtracting 120 from 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
20 can be fit into 110 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 38856.5
If we take 100 away from 110, 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.

On to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 38856.55
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.

The final result is 38856.55 with a remainder of 0.0.
