We look at the division of 774631 by 20 
We're looking to find how many times 20 goes into 774631.

On to step 1:
7 divided by 20 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 20

On to step 2:
77 divided by 20 is 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 60 away from 77, we end up with 17.
Include the next digit (4) from the dividend after 17, then repeat: 174 / 20

Going ahead to step 3:
When dividing 174 by 20, we get 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Deduct 160 from 174 and we're left with 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 20

Let's proceed to step 4:
The number 20 fits into 146 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 387.0
Deduct 140 from 146 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 20

Advancing to step 5:
20 goes into 63 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3873.0
The remainder is 3 after subtracting 60 from 63.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 20

On to step 6:
The number 20 fits into 31 1 times, leaving a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 38731.0
Deduct 20 from 31 and we're left with 11.
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:
If we divide 110 by 20, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 38731.5
The remainder is 10 after subtracting 100 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 38731.55
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 outcome is 38731.55, with a leftover of 0.0.
