45904 ÷ 72 
We want to figure out the number of times 45904 can be divided by 72.

Going ahead to step 1:
72 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 72

On to step 2:
72 can be fit into 45 0 times, resulting in a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Append the next digit (9) from the dividend to 45 and continue with: 459 / 72

On to step 3:
72 can be fit into 459 6 times, resulting in a remainder of 27.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 27 after subtracting 432 from 459.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 72

Advancing to step 4:
270 divided by 72 is 3 with a remainder of 54.
The next digit of our result is 3. 
Result so far: 63.0
If we subtract 216 from 270, we get 54.
Bring next digit (4) of the dividend behind the 54 and repeat the process: 544 / 72

Moving on to step 5:
The number 72 fits into 544 7 times, leaving a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 637.0
Subtract 504 from 544 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 6:
If we divide 400 by 72, we get 5 and a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 637.5
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
The number 72 fits into 400 5 times, leaving a remainder of 40.
The next digit of our result is 5. 
Result so far: 637.55
Subtracting 360 from 400 leaves us 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.

After the division, we end up with 637.55 and a remainder of 0.04.
