We divide 72639510 by 660
Let's see how many times 660 fits into 72639510.

Going ahead to step 1:
If we divide 7 by 660, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 660

Going ahead to step 2:
72 divided by 660 is 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Bring next digit (6) of the dividend behind the 72 and repeat the process: 726 / 660

Going ahead to step 3:
726 divided by 660 is 1 with a remainder of 66.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 660 from 726 leaves us with 66.
Fetch the next digit (3) from the dividend, attach it to 66 and continue: 663 / 660

Step 4:
When dividing 663 by 660, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 660 from 663 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 660

Let's proceed to step 5:
660 goes into 39 0 times with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 110.0
Deduct 0 from 39 and we're left with 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 660

Advancing to step 6:
660 goes into 395 0 times with a remainder of 395.
Write down 0 as next digit of the result. 
Result so far: 1100.0
Subtracting 0 from 395 leaves us with 395.
Grab the next digit (1) from the dividend, add it to 395, then carry on: 3951 / 660

Moving on to step 7:
660 goes into 3951 5 times with a remainder of 651.
Record the quotient 5 as the next digit in the result. 
Result so far: 11005.0
Subtract 3300 from 3951 to get 651.
Take the next digit (0) from the dividend and append it to 651, then repeat: 6510 / 660

Step 8:
The number 660 fits into 6510 9 times, leaving a remainder of 570.
Write down 9 as next digit of the result. 
Result so far: 110059.0
Subtracting 5940 from 6510 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Advancing to step 9:
660 goes into 5700 8 times with a remainder of 420.
The number 8 becomes the next digit in our result. 
Result so far: 110059.8
If we subtract 5280 from 5700, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 10:
The number 660 fits into 4200 6 times, leaving a remainder of 240.
Put 6 as the next digit of the answer. 
Result so far: 110059.86
Subtract 3960 from 4200 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 11:
When dividing 2400 by 660, we get 3 with a remainder of 420.
Record the quotient 3 as the next digit in the result. 
Result so far: 110059.863
The remainder is 420 after subtracting 1980 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 12:
660 can be fit into 4200 6 times, resulting in a remainder of 240.
Put 6 as the next digit of the answer. 
Result so far: 110059.8636
Subtract 3960 from 4200 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 13:
2400 divided by 660 is 3 with a remainder of 420.
Use 3 as the next digit of our solution. 
Result so far: 110059.86363
If we subtract 1980 from 2400, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 14:
660 goes into 4200 6 times with a remainder of 240.
The next digit of our result is 6. 
Result so far: 110059.863636
If we subtract 3960 from 4200, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 15:
660 goes into 2400 3 times with a remainder of 420.
The next digit of our result is 3. 
Result so far: 110059.8636363
Deduct 1980 from 2400 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 16:
660 goes into 4200 6 times with a remainder of 240.
Use 6 as the next digit of our solution. 
Result so far: 110059.86363636
Subtract 3960 from 4200 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 110059.86363636 with a remainder of 2.4e-07.
