We divide 172800 by 75
We want to figure out the number of times 172800 can be divided by 75.

Moving on to step 1:
75 can be fit into 1 0 times, resulting in 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 / 75

Advancing to step 2:
17 divided by 75 is 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 75

Moving on to step 3:
If we divide 172 by 75, we get 2 and a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 22 after subtracting 150 from 172.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 75

Moving on to step 4:
75 goes into 228 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Deduct 225 from 228 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 75

On to step 5:
75 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 230.0
If we take 0 away from 30, we end up with 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 75

Step 6:
75 can be fit into 300 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 2304.0
Subtracting 300 from 300 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:
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: 2304.0
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.

Step 8:
75 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2304.0
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.

Our division results in 2304.0 with a remaining 0.0.
