We divide 313258 by 20
We want to figure out the number of times 313258 can be divided by 20.

Moving on to step 1:
If we divide 3 by 20, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 20

Advancing to step 2:
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: 1.0
Deduct 20 from 31 and we're left with 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 20

Let's proceed to step 3:
20 can be fit into 113 5 times, resulting in a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 100 from 113 to get 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 20

Moving on to step 4:
20 goes into 132 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 156.0
Deduct 120 from 132 and we're left with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 20

On to step 5:
If we divide 125 by 20, we get 6 and a remainder of 5.
The next digit of our result is 6. 
Result so far: 1566.0
The remainder is 5 after subtracting 120 from 125.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 20

Let's proceed to step 6:
When dividing 58 by 20, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 15662.0
Subtract 40 from 58 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
20 goes into 180 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 15662.9
Deduct 180 from 180 and we're left 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.

Moving on to step 8:
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: 15662.9
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.

Let's proceed to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15662.9
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.

The quotient of the division is 15662.9, and the remainder is 0.0.
