We're dividing 170459 by 68 
We want to figure out the number of times 170459 can be divided by 68.

Let's proceed to step 1:
68 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 68

Moving on to step 2:
The number 68 fits into 17 0 times, leaving a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 68

Step 3:
68 goes into 170 2 times with a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 136 from 170 and we're left with 34.
Take the next digit (4) from the dividend and append it to 34, then repeat: 344 / 68

Moving on to step 4:
68 can be fit into 344 5 times, resulting in a remainder of 4.
The next digit of our result is 5. 
Result so far: 25.0
Subtract 340 from 344 to get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 68

On to step 5:
If we divide 45 by 68, we get 0 and a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 250.0
Subtracting 0 from 45 leaves us with 45.
Fetch the next digit (9) from the dividend, attach it to 45 and continue: 459 / 68

On to step 6:
When dividing 459 by 68, we get 6 with a remainder of 51.
Record the quotient 6 as the next digit in the result. 
Result so far: 2506.0
If we subtract 408 from 459, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
If we divide 510 by 68, we get 7 and a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 2506.7
Subtract 476 from 510 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
68 goes into 340 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2506.75
The remainder is 0 after subtracting 340 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
If we divide 0 by 68, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2506.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
0 divided by 68 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2506.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 2506.75 with a remainder of 0.0.
