We look at the division of 503891 by 72 
We want to figure out the number of times 503891 can be divided by 72.

Going ahead to step 1:
The number 72 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 72

Step 2:
When dividing 50 by 72, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Bring next digit (3) of the dividend behind the 50 and repeat the process: 503 / 72

Let's proceed to step 3:
503 divided by 72 is 6 with a remainder of 71.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 432 from 503 and we're left with 71.
Append the next digit (8) from the dividend to 71 and continue with: 718 / 72

Step 4:
72 goes into 718 9 times with a remainder of 70.
Put 9 as the next digit of the answer. 
Result so far: 69.0
If we subtract 648 from 718, we get 70.
Take the next digit (9) from the dividend and append it to 70, then repeat: 709 / 72

Going ahead to step 5:
The number 72 fits into 709 9 times, leaving a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 699.0
If we subtract 648 from 709, we get 61.
Append the next digit (1) from the dividend to 61 and continue with: 611 / 72

Moving on to step 6:
If we divide 611 by 72, we get 8 and a remainder of 35.
Write down 8 as next digit of the result. 
Result so far: 6998.0
Subtract 576 from 611 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
72 goes into 350 4 times with a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 6998.4
Subtract 288 from 350 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 8:
The number 72 fits into 620 8 times, leaving a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 6998.48
Subtracting 576 from 620 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
When dividing 440 by 72, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 6998.486
If we take 432 away from 440, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
72 can be fit into 80 1 times, resulting in a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 6998.4861
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
80 divided by 72 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 6998.48611
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 6998.48611 with a remainder of 8e-06.
