We look at the division of 720725 by 42 
We're looking to find how many times 42 goes into 720725.

Let's proceed to step 1:
If we divide 7 by 42, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 42

Going ahead to step 2:
When dividing 72 by 42, we get 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 42 from 72, we get 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 42

Advancing to step 3:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 294 from 300, we get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 42

Step 4:
If we divide 67 by 42, we get 1 and a remainder of 25.
The next digit of our result is 1. 
Result so far: 171.0
Subtracting 42 from 67 leaves us with 25.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 42

Advancing to step 5:
The number 42 fits into 252 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 1716.0
The remainder is 0 after subtracting 252 from 252.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 42

Advancing to step 6:
42 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 17160.0
Subtract 0 from 5 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
When dividing 50 by 42, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 17160.1
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
When dividing 80 by 42, we get 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 17160.11
Subtracting 42 from 80 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 17160.11 and a remainder of 0.038.
