623128 ÷ 72 
We want to figure out the number of times 623128 can be divided by 72.

Going ahead to step 1:
When dividing 6 by 72, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 72

Moving on to step 2:
If we divide 62 by 72, we get 0 and a remainder of 62.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 62 and we're left with 62.
Take the next digit (3) from the dividend and append it to 62, then repeat: 623 / 72

Going ahead to step 3:
When dividing 623 by 72, we get 8 with a remainder of 47.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 47 after subtracting 576 from 623.
Bring next digit (1) of the dividend behind the 47 and repeat the process: 471 / 72

Let's proceed to step 4:
The number 72 fits into 471 6 times, leaving a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 86.0
If we subtract 432 from 471, we get 39.
Append the next digit (2) from the dividend to 39 and continue with: 392 / 72

Advancing to step 5:
The number 72 fits into 392 5 times, leaving a remainder of 32.
Use 5 as the next digit of our solution. 
Result so far: 865.0
If we subtract 360 from 392, we get 32.
Include the next digit (8) from the dividend after 32, then repeat: 328 / 72

Moving on to step 6:
328 divided by 72 is 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 8654.0
The remainder is 40 after subtracting 288 from 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
When dividing 400 by 72, we get 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 8654.5
Subtract 360 from 400 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.

Going ahead to step 8:
72 can be fit into 400 5 times, resulting in a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 8654.55
If we take 360 away from 400, 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.

The final result is 8654.55 with a remainder of 0.04.
