We look at the division of 78426584 by 72 
We want to divide 78426584 by 72.

Advancing to step 1:
When dividing 7 by 72, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 72

Let's proceed to step 2:
When dividing 78 by 72, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 72 from 78, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 72

Advancing to step 3:
When dividing 64 by 72, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (2) from the dividend to 64 and continue with: 642 / 72

On to step 4:
72 can be fit into 642 8 times, resulting in a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 108.0
If we subtract 576 from 642, we get 66.
Bring next digit (6) of the dividend behind the 66 and repeat the process: 666 / 72

Moving on to step 5:
72 goes into 666 9 times with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 1089.0
Deduct 648 from 666 and we're left with 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 72

Going ahead to step 6:
72 goes into 185 2 times with a remainder of 41.
Write down 2 as next digit of the result. 
Result so far: 10892.0
If we subtract 144 from 185, we get 41.
Fetch the next digit (8) from the dividend, attach it to 41 and continue: 418 / 72

Moving on to step 7:
The number 72 fits into 418 5 times, leaving a remainder of 58.
Record the quotient 5 as the next digit in the result. 
Result so far: 108925.0
Deduct 360 from 418 and we're left with 58.
Bring next digit (4) of the dividend behind the 58 and repeat the process: 584 / 72

Going ahead to step 8:
72 can be fit into 584 8 times, resulting in a remainder of 8.
The next digit of our result is 8. 
Result so far: 1089258.0
Subtract 576 from 584 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
The number 72 fits into 80 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 1089258.1
If we take 72 away from 80, 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.

Let's proceed to step 10:
80 divided by 72 is 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1089258.11
Deduct 72 from 80 and we're left 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.

After the division, we end up with 1089258.11 and a remainder of 0.008.
