313383 ÷ 20 
We're looking to find how many times 20 goes into 313383.

Going ahead to step 1:
When dividing 3 by 20, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 20

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
Subtract 20 from 31 to get 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 20

Step 3:
If we divide 113 by 20, we get 5 and a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 100 from 113 leaves us with 13.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 20

Going ahead to step 4:
133 divided by 20 is 6 with a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 156.0
Subtract 120 from 133 to get 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 20

Advancing to step 5:
20 can be fit into 138 6 times, resulting in a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 1566.0
Subtracting 120 from 138 leaves us with 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 20

Going ahead to step 6:
20 goes into 183 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 15669.0
The remainder is 3 after subtracting 180 from 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
When dividing 30 by 20, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 15669.1
If we take 20 away from 30, we end up 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.

Advancing to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15669.15
Deduct 100 from 100 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.

Step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15669.15
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 10:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15669.15
Deduct 0 from 0 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.

The final result is 15669.15 with a remainder of 0.0.
