We divide 351338 by 20
Our goal is to divide 351338 by 20.

Going ahead to step 1:
If we divide 3 by 20, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 20

On to step 2:
If we divide 35 by 20, we get 1 and a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 20 from 35, we get 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 20

Step 3:
When dividing 151 by 20, we get 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 140 from 151 to get 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 20

Advancing to step 4:
The number 20 fits into 113 5 times, leaving a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 175.0
Subtract 100 from 113 to get 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 20

Going ahead to step 5:
20 goes into 133 6 times with a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 1756.0
If we subtract 120 from 133, we get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 20

Going ahead to step 6:
If we divide 138 by 20, we get 6 and a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 17566.0
If we take 120 away from 138, we end up with 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:
180 divided by 20 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 17566.9
If we subtract 180 from 180, 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.

Advancing to step 8:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17566.9
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.

Going ahead to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17566.9
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 final outcome is 17566.9, with a leftover of 0.0.
