We look at the division of 346560 by 20 
We want to divide 346560 by 20.

Advancing to step 1:
If we divide 3 by 20, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 20

Step 2:
The number 20 fits into 34 1 times, leaving a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 14 after subtracting 20 from 34.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 20

Going ahead to step 3:
20 can be fit into 146 7 times, resulting in a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 140 from 146, we get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 20

Let's proceed to step 4:
The number 20 fits into 65 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 173.0
The remainder is 5 after subtracting 60 from 65.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 20

Advancing to step 5:
If we divide 56 by 20, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 1732.0
The remainder is 16 after subtracting 40 from 56.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 20

Going ahead to step 6:
If we divide 160 by 20, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 17328.0
Deduct 160 from 160 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 7:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17328.0
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.

Moving on to step 8:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17328.0
Subtracting 0 from 0 leaves us 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 17328.0, with a leftover of 0.0.
