Let's divide 172551 by 75
Our goal is to divide 172551 by 75.

Advancing to step 1:
The number 75 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 75

On to step 2:
17 divided by 75 is 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 75

Let's proceed to step 3:
75 goes into 172 2 times with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 150 from 172, we get 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 75

Moving on to step 4:
225 divided by 75 is 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Deduct 225 from 225 and we're left with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 75

Going ahead to step 5:
If we divide 5 by 75, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 230.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 75

On to step 6:
51 divided by 75 is 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 2300.0
If we take 0 away from 51, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
The number 75 fits into 510 6 times, leaving a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 2300.6
The remainder is 60 after subtracting 450 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
If we divide 600 by 75, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 2300.68
Deduct 600 from 600 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.

On to step 9:
When dividing 0 by 75, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2300.68
Subtracting 0 from 0 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.

On to step 10:
0 divided by 75 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2300.68
If we take 0 away from 0, we end up 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.

The final outcome is 2300.68, with a leftover of 0.0.
