We're dividing 42724 by 75 
We want to figure out the number of times 42724 can be divided by 75.

On to step 1:
75 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 75

Step 2:
If we divide 42 by 75, we get 0 and a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Bring next digit (7) of the dividend behind the 42 and repeat the process: 427 / 75

Step 3:
When dividing 427 by 75, we get 5 with a remainder of 52.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 375 from 427 leaves us with 52.
Bring next digit (2) of the dividend behind the 52 and repeat the process: 522 / 75

Going ahead to step 4:
When dividing 522 by 75, we get 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 56.0
The remainder is 72 after subtracting 450 from 522.
Grab the next digit (4) from the dividend, add it to 72, then carry on: 724 / 75

Advancing to step 5:
724 divided by 75 is 9 with a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 569.0
If we take 675 away from 724, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 6:
75 goes into 490 6 times with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 569.6
If we take 450 away from 490, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
If we divide 400 by 75, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 569.65
If we take 375 away from 400, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 8:
If we divide 250 by 75, we get 3 and a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 569.653
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
If we divide 250 by 75, we get 3 and a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 569.6533
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 569.6533, with a leftover of 0.00025.
