863839 divided by 34 
We want to figure out the number of times 863839 can be divided by 34.

Moving on to step 1:
The number 34 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 34

Moving on to step 2:
34 can be fit into 86 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 68 from 86 and we're left with 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 34

Going ahead to step 3:
183 divided by 34 is 5 with a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Deduct 170 from 183 and we're left with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 34

On to step 4:
The number 34 fits into 138 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 254.0
If we take 136 away from 138, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 34

On to step 5:
When dividing 23 by 34, we get 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 2540.0
Subtract 0 from 23 to get 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 34

Advancing to step 6:
34 goes into 239 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 25407.0
Deduct 238 from 239 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
34 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 25407.0
Deduct 0 from 10 and we're left 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.

Let's proceed to step 8:
100 divided by 34 is 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 25407.02
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.

Step 9:
320 divided by 34 is 9 with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 25407.029
The remainder is 14 after subtracting 306 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
When dividing 140 by 34, we get 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 25407.0294
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.

Step 11:
If we divide 40 by 34, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 25407.02941
Subtract 34 from 40 to 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.

On to step 12:
When dividing 60 by 34, we get 1 with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 25407.029411
If we subtract 34 from 60, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 25407.029411, with a leftover of 2.6e-06.
