We look at the division of 66530686 by 72 
We want to figure out the number of times 66530686 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
The remainder is 6 after subtracting 0 from 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 72

Moving on to step 2:
When dividing 66 by 72, we get 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (5) from the dividend after 66, then repeat: 665 / 72

Advancing to step 3:
665 divided by 72 is 9 with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 17 after subtracting 648 from 665.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 72

On to step 4:
The number 72 fits into 173 2 times, leaving a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 92.0
If we take 144 away from 173, we end up with 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 72

Going ahead to step 5:
290 divided by 72 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 924.0
Deduct 288 from 290 and we're left with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 72

Let's proceed to step 6:
72 can be fit into 26 0 times, resulting in a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 9240.0
If we subtract 0 from 26, we get 26.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 72

Moving on to step 7:
The number 72 fits into 268 3 times, leaving a remainder of 52.
Record the quotient 3 as the next digit in the result. 
Result so far: 92403.0
Subtracting 216 from 268 leaves us with 52.
Append the next digit (6) from the dividend to 52 and continue with: 526 / 72

Going ahead to step 8:
The number 72 fits into 526 7 times, leaving a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 924037.0
The remainder is 22 after subtracting 504 from 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
72 goes into 220 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 924037.3
Deduct 216 from 220 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
If we divide 40 by 72, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 924037.3
If we take 0 away from 40, 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.

On to step 11:
If we divide 400 by 72, we get 5 and a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 924037.305
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.

Moving on to step 12:
When dividing 400 by 72, we get 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 924037.3055
Subtracting 360 from 400 leaves us 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 quotient of the division is 924037.3055, and the remainder is 0.0004.
