Let's divide 623170 by 72
We're looking to find how many times 72 goes into 623170.

Going ahead to step 1:
The number 72 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 72

Moving on to step 2:
72 can be fit into 62 0 times, resulting in a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 62 after subtracting 0 from 62.
Take the next digit (3) from the dividend and append it to 62, then repeat: 623 / 72

On to step 3:
72 can be fit into 623 8 times, resulting in a remainder of 47.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 576 from 623, we get 47.
Fetch the next digit (1) from the dividend, attach it to 47 and continue: 471 / 72

Moving on to step 4:
471 divided by 72 is 6 with a remainder of 39.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtracting 432 from 471 leaves us with 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 72

Advancing to step 5:
72 can be fit into 397 5 times, resulting in a remainder of 37.
Put 5 as the next digit of the answer. 
Result so far: 865.0
If we subtract 360 from 397, we get 37.
Take the next digit (0) from the dividend and append it to 37, then repeat: 370 / 72

Advancing to step 6:
72 goes into 370 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 8655.0
The remainder is 10 after subtracting 360 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
100 divided by 72 is 1 with a remainder of 28.
The next digit of our result is 1. 
Result so far: 8655.1
Subtracting 72 from 100 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
280 divided by 72 is 3 with a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 8655.13
Subtracting 216 from 280 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
When dividing 640 by 72, we get 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 8655.138
If we take 576 away from 640, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 10:
If we divide 640 by 72, we get 8 and a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 8655.1388
If we take 576 away from 640, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 8655.1388, with a leftover of 0.00064.
