Let's divide 339746 by 20
We're looking to find how many times 20 goes into 339746.

Moving on to step 1:
3 divided by 20 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 20

On to step 2:
If we divide 33 by 20, we get 1 and a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 20 away from 33, we end up with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 20

Let's proceed to step 3:
20 can be fit into 139 6 times, resulting in a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 120 from 139 and we're left with 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 20

Advancing to step 4:
20 can be fit into 197 9 times, resulting in a remainder of 17.
The next digit of our result is 9. 
Result so far: 169.0
Subtracting 180 from 197 leaves us with 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 20

Advancing to step 5:
174 divided by 20 is 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 1698.0
Deduct 160 from 174 and we're left with 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 20

Let's proceed to step 6:
If we divide 146 by 20, we get 7 and a remainder of 6.
The next digit of our result is 7. 
Result so far: 16987.0
Deduct 140 from 146 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
If we divide 60 by 20, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 16987.3
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16987.3
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.

Step 9:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16987.3
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.

Our division results in 16987.3 with a remaining 0.0.
