We're dividing 6712656 by 20 
We're looking to find how many times 20 goes into 6712656.

Going ahead to step 1:
20 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 20

On to step 2:
When dividing 67 by 20, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 60 from 67 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 20

Step 3:
The number 20 fits into 71 3 times, leaving a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtracting 60 from 71 leaves us with 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 20

Moving on to step 4:
If we divide 112 by 20, we get 5 and a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 335.0
Deduct 100 from 112 and we're left with 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 20

Advancing to step 5:
The number 20 fits into 126 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 3356.0
Deduct 120 from 126 and we're left with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 20

Advancing to step 6:
When dividing 65 by 20, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 33563.0
Subtracting 60 from 65 leaves us with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 20

Advancing to step 7:
20 goes into 56 2 times with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 335632.0
Subtracting 40 from 56 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
If we divide 160 by 20, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 335632.8
If we take 160 away from 160, 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.

Step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 335632.8
If we take 0 away from 0, 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 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 335632.8
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.

After the division, we end up with 335632.8 and a remainder of 0.0.
