We look at the division of 857960 by 34 
Our goal is to divide 857960 by 34.

Advancing to step 1:
34 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 34

Step 2:
The number 34 fits into 85 2 times, leaving a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 68 away from 85, we end up with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 34

Advancing to step 3:
34 can be fit into 177 5 times, resulting in a remainder of 7.
The next digit of our result is 5. 
Result so far: 25.0
The remainder is 7 after subtracting 170 from 177.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 34

On to step 4:
The number 34 fits into 79 2 times, leaving a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 252.0
Subtracting 68 from 79 leaves us with 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 34

Moving on to step 5:
If we divide 116 by 34, we get 3 and a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 2523.0
Deduct 102 from 116 and we're left with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 34

Going ahead to step 6:
The number 34 fits into 140 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 25234.0
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.

Let's proceed to step 7:
When dividing 40 by 34, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 25234.1
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.

Going ahead to step 8:
34 goes into 60 1 times with a remainder of 26.
The next digit of our result is 1. 
Result so far: 25234.11
Subtract 34 from 60 to 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 25234.11, with a leftover of 0.026.
