We look at the division of 7423 by 75 
We're looking to find how many times 75 goes into 7423.

Moving on to step 1:
When dividing 7 by 75, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 75

Advancing to step 2:
75 can be fit into 74 0 times, resulting in a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Bring next digit (2) of the dividend behind the 74 and repeat the process: 742 / 75

Going ahead to step 3:
When dividing 742 by 75, we get 9 with a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 675 from 742 to get 67.
Grab the next digit (3) from the dividend, add it to 67, then carry on: 673 / 75

Moving on to step 4:
75 goes into 673 8 times with a remainder of 73.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
Deduct 600 from 673 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 5:
If we divide 730 by 75, we get 9 and a remainder of 55.
The number 9 becomes the next digit in our result. 
Result so far: 98.9
If we subtract 675 from 730, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 6:
75 can be fit into 550 7 times, resulting in a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 98.97
If we take 525 away from 550, 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.

Step 7:
250 divided by 75 is 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 98.973
Subtract 225 from 250 to 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.

Advancing to step 8:
The number 75 fits into 250 3 times, leaving a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 98.9733
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 98.9733, with a leftover of 0.00025.
