We look at the division of 256678 by 17 
We want to figure out the number of times 256678 can be divided by 17.

Let's proceed to step 1:
The number 17 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 17

Let's proceed to step 2:
17 goes into 25 1 times with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 17 away from 25, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 17

On to step 3:
If we divide 86 by 17, we get 5 and a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 85 from 86 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 17

Moving on to step 4:
If we divide 16 by 17, we get 0 and a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 150.0
If we take 0 away from 16, we end up with 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 17

Step 5:
The number 17 fits into 167 9 times, leaving a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 1509.0
If we take 153 away from 167, we end up with 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 17

Advancing to step 6:
If we divide 148 by 17, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 15098.0
Subtracting 136 from 148 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
When dividing 120 by 17, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 15098.7
Deduct 119 from 120 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.

Advancing to step 8:
10 divided by 17 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 15098.7
If we take 0 away from 10, we end up 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.

Going ahead to step 9:
100 divided by 17 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 15098.705
The remainder is 15 after subtracting 85 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
17 can be fit into 150 8 times, resulting in a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 15098.7058
If we take 136 away from 150, we end up 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 11:
The number 17 fits into 140 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 15098.70588
If we subtract 136 from 140, we 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.

The final outcome is 15098.70588, with a leftover of 4e-06.
