The remainder is 8 after subtracting 0 from 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 34

Advancing to step 2:
The number 34 fits into 87 2 times, leaving a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 68 from 87 and we're left with 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 34

Advancing to step 3:
34 can be fit into 193 5 times, resulting in a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtracting 170 from 193 leaves us with 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 34

Step 4:
34 can be fit into 235 6 times, resulting in a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 256.0
Subtract 204 from 235 to get 31.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 34

Moving on to step 5:
34 goes into 314 9 times with a remainder of 8.
The next digit of our result is 9. 
Result so far: 2569.0
The remainder is 8 after subtracting 306 from 314.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 34

Advancing to step 6:
If we divide 83 by 34, we get 2 and a remainder of 15.
The next digit of our result is 2. 
Result so far: 25692.0
Subtracting 68 from 83 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
The number 34 fits into 150 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 25692.4
Subtracting 136 from 150 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.

On to step 8:
The number 34 fits into 140 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 25692.44
The remainder is 4 after subtracting 136 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 25692.44 with a remaining 0.004.
