We divide 661575 by 72
We're looking to find how many times 72 goes into 661575.

Step 1:
If we divide 6 by 72, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 72

On to step 2:
72 goes into 66 0 times with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 72

Advancing to step 3:
72 can be fit into 661 9 times, resulting in a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 648 from 661 and we're left with 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 72

Moving on to step 4:
The number 72 fits into 135 1 times, leaving a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Subtracting 72 from 135 leaves us with 63.
Grab the next digit (7) from the dividend, add it to 63, then carry on: 637 / 72

On to step 5:
The number 72 fits into 637 8 times, leaving a remainder of 61.
Write down 8 as next digit of the result. 
Result so far: 918.0
If we take 576 away from 637, we end up with 61.
Fetch the next digit (5) from the dividend, attach it to 61 and continue: 615 / 72

Going ahead to step 6:
72 can be fit into 615 8 times, resulting in a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 9188.0
If we subtract 576 from 615, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
390 divided by 72 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 9188.5
The remainder is 30 after subtracting 360 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
72 can be fit into 300 4 times, resulting in a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 9188.54
Deduct 288 from 300 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
72 can be fit into 120 1 times, resulting in a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 9188.541
If we take 72 away from 120, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
The number 72 fits into 480 6 times, leaving a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 9188.5416
The remainder is 48 after subtracting 432 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
When dividing 480 by 72, we get 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 9188.54166
Subtract 432 from 480 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

In conclusion, the division gives 9188.54166 with a balance of 4.8e-05.
