903612 ÷ 72 
We want to figure out the number of times 903612 can be divided by 72.

Moving on to step 1:
When dividing 9 by 72, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 72

Moving on to step 2:
If we divide 90 by 72, we get 1 and a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 18 after subtracting 72 from 90.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 72

Advancing to step 3:
When dividing 183 by 72, we get 2 with a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 39 after subtracting 144 from 183.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 72

Let's proceed to step 4:
The number 72 fits into 396 5 times, leaving a remainder of 36.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
If we take 360 away from 396, we end up with 36.
Grab the next digit (1) from the dividend, add it to 36, then carry on: 361 / 72

Going ahead to step 5:
72 can be fit into 361 5 times, resulting in a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 1255.0
If we take 360 away from 361, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 72

Let's proceed to step 6:
The number 72 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 12550.0
If we take 0 away from 12, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
72 goes into 120 1 times with a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 12550.1
The remainder is 48 after subtracting 72 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
72 can be fit into 480 6 times, resulting in a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 12550.16
The remainder is 48 after subtracting 432 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
480 divided by 72 is 6 with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 12550.166
Subtract 432 from 480 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 12550.166 and a remainder of 0.0048.
