We're dividing 764661 by 20 
We want to divide 764661 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
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 20

On to step 2:
If we divide 76 by 20, we get 3 and a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 60 from 76 to get 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 20

On to step 3:
The number 20 fits into 164 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 38.0
Subtract 160 from 164 to get 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 20

Advancing to step 4:
The number 20 fits into 46 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 382.0
Subtract 40 from 46 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 20

Moving on to step 5:
20 can be fit into 66 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3823.0
If we take 60 away from 66, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 20

Advancing to step 6:
The number 20 fits into 61 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 38233.0
If we subtract 60 from 61, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
20 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 38233.0
Deduct 0 from 10 and we're left 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:
If we divide 100 by 20, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 38233.05
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.

On to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 38233.05
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 10:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 38233.05
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.

After the division, we end up with 38233.05 and a remainder of 0.0.
