We look at the division of 664187 by 34 
We want to divide 664187 by 34.

On to step 1:
6 divided by 34 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 34

Step 2:
If we divide 66 by 34, we get 1 and a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 34 from 66 to get 32.
Bring next digit (4) of the dividend behind the 32 and repeat the process: 324 / 34

On to step 3:
324 divided by 34 is 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 306 from 324 to get 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 34

Going ahead to step 4:
If we divide 181 by 34, we get 5 and a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 195.0
Subtract 170 from 181 to get 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 34

On to step 5:
118 divided by 34 is 3 with a remainder of 16.
The next digit of our result is 3. 
Result so far: 1953.0
If we take 102 away from 118, we end up with 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 34

Advancing to step 6:
34 can be fit into 167 4 times, resulting in a remainder of 31.
The number 4 becomes the next digit in our result. 
Result so far: 19534.0
Deduct 136 from 167 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
When dividing 310 by 34, we get 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 19534.9
Subtract 306 from 310 to get 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 8:
When dividing 40 by 34, we get 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 19534.91
If we subtract 34 from 40, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
34 goes into 60 1 times with a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 19534.911
Deduct 34 from 60 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 19534.911 with a remaining 0.0026.
