763649 divided by 20 
Let's see how many times 20 fits into 763649.

On to step 1:
20 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 20

On to step 2:
The number 20 fits into 76 3 times, leaving a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 60 away from 76, we end up with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 20

Advancing to step 3:
20 goes into 163 8 times with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 38.0
The remainder is 3 after subtracting 160 from 163.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 20

Let's proceed to step 4:
36 divided by 20 is 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 381.0
If we take 20 away from 36, we end up with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 20

Advancing to step 5:
If we divide 164 by 20, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 3818.0
If we take 160 away from 164, we end up with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 20

On to step 6:
When dividing 49 by 20, we get 2 with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 38182.0
If we subtract 40 from 49, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
The number 20 fits into 90 4 times, leaving a remainder of 10.
The next digit of our result is 4. 
Result so far: 38182.4
The remainder is 10 after subtracting 80 from 90.
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.
Put 5 as the next digit of the answer. 
Result so far: 38182.45
If we take 100 away from 100, 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.

Advancing to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 38182.45
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:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 38182.45
Subtracting 0 from 0 leaves us 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.

Our division results in 38182.45 with a remaining 0.0.
