We're dividing 172458 by 26 
Our goal is to divide 172458 by 26.

Step 1:
26 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 26

Moving on to step 2:
If we divide 17 by 26, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 26

On to step 3:
172 divided by 26 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 156 from 172, we get 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 26

On to step 4:
26 goes into 164 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 66.0
Deduct 156 from 164 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 26

Moving on to step 5:
If we divide 85 by 26, we get 3 and a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 663.0
If we take 78 away from 85, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 26

Advancing to step 6:
26 can be fit into 78 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 6633.0
Subtracting 78 from 78 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
26 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6633.0
Deduct 0 from 0 and we're left with 0.
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 8:
0 divided by 26 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6633.0
If we subtract 0 from 0, we 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.

After the division, we end up with 6633.0 and a remainder of 0.0.
