We divide 668131 by 20
We want to divide 668131 by 20.

On to step 1:
6 divided by 20 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 20

Moving on to step 2:
20 can be fit into 66 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 6 after subtracting 60 from 66.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 20

Advancing to step 3:
20 goes into 68 3 times with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
The remainder is 8 after subtracting 60 from 68.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 20

Advancing to step 4:
If we divide 81 by 20, we get 4 and a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 334.0
Subtracting 80 from 81 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 20

Let's proceed to step 5:
20 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 3340.0
If we take 0 away from 13, we end up with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 20

On to step 6:
131 divided by 20 is 6 with a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 33406.0
Subtracting 120 from 131 leaves us 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.

On to step 7:
When dividing 110 by 20, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 33406.5
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:
100 divided by 20 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 33406.55
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.

The quotient of the division is 33406.55, and the remainder is 0.0.
