108729 ÷ 75 
We want to figure out the number of times 108729 can be divided by 75.

Let's proceed to step 1:
75 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 75

Let's proceed to step 2:
75 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 75

Going ahead to step 3:
When dividing 108 by 75, we get 1 with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 75 from 108 leaves us with 33.
Bring next digit (7) of the dividend behind the 33 and repeat the process: 337 / 75

Advancing to step 4:
75 goes into 337 4 times with a remainder of 37.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 300 from 337 and we're left with 37.
Grab the next digit (2) from the dividend, add it to 37, then carry on: 372 / 75

Let's proceed to step 5:
When dividing 372 by 75, we get 4 with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 144.0
If we take 300 away from 372, we end up with 72.
Fetch the next digit (9) from the dividend, attach it to 72 and continue: 729 / 75

On to step 6:
75 goes into 729 9 times with a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 1449.0
If we take 675 away from 729, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 7:
The number 75 fits into 540 7 times, leaving a remainder of 15.
The next digit of our result is 7. 
Result so far: 1449.7
The remainder is 15 after subtracting 525 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
150 divided by 75 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 1449.72
The remainder is 0 after subtracting 150 from 150.
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:
The number 75 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1449.72
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.

Step 10:
0 divided by 75 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1449.72
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.

The quotient of the division is 1449.72, and the remainder is 0.0.
