We're dividing 708139 by 20 
Let's see how many times 20 fits into 708139.

On to step 1:
If we divide 7 by 20, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 20

On to step 2:
If we divide 70 by 20, we get 3 and a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 60 from 70 to get 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 20

Going ahead to step 3:
20 goes into 108 5 times with a remainder of 8.
The next digit of our result is 5. 
Result so far: 35.0
The remainder is 8 after subtracting 100 from 108.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 20

Advancing to step 4:
20 goes into 81 4 times with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 354.0
The remainder is 1 after subtracting 80 from 81.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 20

Step 5:
When dividing 13 by 20, we get 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 3540.0
If we take 0 away from 13, we end up with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 20

On to step 6:
20 can be fit into 139 6 times, resulting in a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 35406.0
If we take 120 away from 139, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
When dividing 190 by 20, we get 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 35406.9
If we subtract 180 from 190, we 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.

Advancing to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 35406.95
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.

Advancing to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 35406.95
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.

Going ahead to step 10:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 35406.95
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.

After the division, we end up with 35406.95 and a remainder of 0.0.
