Let's divide 639720 by 34
Our goal is to divide 639720 by 34.

Going ahead to step 1:
6 divided by 34 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 34

Advancing to step 2:
34 can be fit into 63 1 times, resulting in a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 34 from 63, we get 29.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 34

Moving on to step 3:
299 divided by 34 is 8 with a remainder of 27.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 272 from 299 to get 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 34

Moving on to step 4:
If we divide 277 by 34, we get 8 and a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 188.0
If we subtract 272 from 277, we get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 34

Step 5:
52 divided by 34 is 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 1881.0
If we take 34 away from 52, we end up with 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 34

Going ahead to step 6:
When dividing 180 by 34, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 18815.0
Subtracting 170 from 180 leaves us with 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 7:
The number 34 fits into 100 2 times, leaving a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 18815.2
If we take 68 away from 100, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 8:
The number 34 fits into 320 9 times, leaving a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 18815.29
Subtracting 306 from 320 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
The number 34 fits into 140 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 18815.294
Deduct 136 from 140 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
If we divide 40 by 34, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 18815.2941
Deduct 34 from 40 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 11:
34 goes into 60 1 times with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 18815.29411
The remainder is 26 after subtracting 34 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 18815.29411 and a remainder of 2.6e-05.
