Let's divide 857503 by 72
We want to figure out the number of times 857503 can be divided by 72.

Advancing to step 1:
When dividing 8 by 72, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 72

Moving on to step 2:
When dividing 85 by 72, we get 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 13 after subtracting 72 from 85.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 72

Moving on to step 3:
If we divide 137 by 72, we get 1 and a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 72 from 137 leaves us with 65.
Grab the next digit (5) from the dividend, add it to 65, then carry on: 655 / 72

Let's proceed to step 4:
The number 72 fits into 655 9 times, leaving a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 119.0
If we subtract 648 from 655, we get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 72

Step 5:
72 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 1190.0
The remainder is 70 after subtracting 0 from 70.
Bring next digit (3) of the dividend behind the 70 and repeat the process: 703 / 72

Moving on to step 6:
72 goes into 703 9 times with a remainder of 55.
Write down 9 as next digit of the result. 
Result so far: 11909.0
Deduct 648 from 703 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 7:
72 goes into 550 7 times with a remainder of 46.
Put 7 as the next digit of the answer. 
Result so far: 11909.7
Deduct 504 from 550 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
460 divided by 72 is 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 11909.76
If we take 432 away from 460, we end up 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 9:
When dividing 280 by 72, we get 3 with a remainder of 64.
Record the quotient 3 as the next digit in the result. 
Result so far: 11909.763
If we take 216 away from 280, 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.

Let's proceed to step 10:
72 can be fit into 640 8 times, resulting in a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 11909.7638
Deduct 576 from 640 and we're left 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.

Moving on to step 11:
When dividing 640 by 72, we get 8 with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 11909.76388
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 11909.76388, with a leftover of 6.4e-05.
