We divide 340129 by 20
We want to divide 340129 by 20.

Let's proceed to step 1:
The number 20 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 20

Advancing to step 2:
The number 20 fits into 34 1 times, leaving a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 20 from 34, we get 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 20

Going ahead to step 3:
20 goes into 140 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 140 from 140, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 20

Advancing to step 4:
20 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 170.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 20

On to step 5:
When dividing 12 by 20, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 1700.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 20

Going ahead to step 6:
The number 20 fits into 129 6 times, leaving a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 17006.0
If we take 120 away from 129, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
20 goes into 90 4 times with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 17006.4
Subtract 80 from 90 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 17006.45
Subtracting 100 from 100 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.

Going ahead to step 9:
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: 17006.45
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.

Going ahead to step 10:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17006.45
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.

Our division results in 17006.45 with a remaining 0.0.
