We look at the division of 723960 by 66 
Let's see how many times 66 fits into 723960.

Let's proceed to step 1:
The number 66 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 66

Advancing to step 2:
66 goes into 72 1 times with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
If we take 66 away from 72, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 66

Step 3:
66 goes into 63 0 times with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 63 and we're left with 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 66

Advancing to step 4:
66 can be fit into 639 9 times, resulting in a remainder of 45.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
Subtract 594 from 639 to get 45.
Append the next digit (6) from the dividend to 45 and continue with: 456 / 66

Step 5:
66 can be fit into 456 6 times, resulting in a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 1096.0
Deduct 396 from 456 and we're left with 60.
Take the next digit (0) from the dividend and append it to 60, then repeat: 600 / 66

Advancing to step 6:
The number 66 fits into 600 9 times, leaving a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 10969.0
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
66 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 10969.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
When dividing 600 by 66, we get 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 10969.09
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
66 can be fit into 60 0 times, resulting in a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 10969.09
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
When dividing 600 by 66, we get 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 10969.0909
If we take 594 away from 600, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
When dividing 60 by 66, we get 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 10969.0909
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
66 can be fit into 600 9 times, resulting in a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 10969.090909
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
60 divided by 66 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 10969.090909
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 14:
The number 66 fits into 600 9 times, leaving a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 10969.09090909
Subtracting 594 from 600 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 10969.09090909 with a balance of 6e-09.
