We're dividing 42817 by 34 
We want to divide 42817 by 34.

Advancing to step 1:
34 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 34

Moving on to step 2:
The number 34 fits into 42 1 times, leaving a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 8 after subtracting 34 from 42.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 34

Step 3:
If we divide 88 by 34, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 68 from 88, we get 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 34

Advancing to step 4:
201 divided by 34 is 5 with a remainder of 31.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
Subtract 170 from 201 to get 31.
Bring next digit (7) of the dividend behind the 31 and repeat the process: 317 / 34

On to step 5:
When dividing 317 by 34, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 1259.0
Deduct 306 from 317 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 6:
34 can be fit into 110 3 times, resulting in a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 1259.3
If we take 102 away from 110, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
When dividing 80 by 34, we get 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 1259.32
Subtract 68 from 80 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
If we divide 120 by 34, we get 3 and a remainder of 18.
The next digit of our result is 3. 
Result so far: 1259.323
Subtracting 102 from 120 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
The number 34 fits into 180 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 1259.3235
Subtract 170 from 180 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.

Let's proceed to step 10:
100 divided by 34 is 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 1259.32352
Subtracting 68 from 100 leaves us 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.

On to step 11:
When dividing 320 by 34, we get 9 with a remainder of 14.
The next digit of our result is 9. 
Result so far: 1259.323529
If we subtract 306 from 320, we get 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 12:
When dividing 140 by 34, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 1259.3235294
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.

Going ahead to step 13:
The number 34 fits into 40 1 times, leaving a remainder of 6.
The next digit of our result is 1. 
Result so far: 1259.32352941
Subtracting 34 from 40 leaves us 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.

The final outcome is 1259.32352941, with a leftover of 6e-09.
