561207 ÷ 66 
We want to figure out the number of times 561207 can be divided by 66.

Step 1:
66 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 66

Advancing to step 2:
When dividing 56 by 66, we get 0 with a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 56 leaves us with 56.
Bring next digit (1) of the dividend behind the 56 and repeat the process: 561 / 66

Advancing to step 3:
When dividing 561 by 66, we get 8 with a remainder of 33.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 33 after subtracting 528 from 561.
Bring next digit (2) of the dividend behind the 33 and repeat the process: 332 / 66

Going ahead to step 4:
66 can be fit into 332 5 times, resulting in a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
Subtracting 330 from 332 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 66

Moving on to step 5:
66 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 850.0
Subtracting 0 from 20 leaves us with 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 66

Step 6:
When dividing 207 by 66, we get 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 8503.0
Subtracting 198 from 207 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
66 goes into 90 1 times with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 8503.1
If we take 66 away from 90, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
66 can be fit into 240 3 times, resulting in a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 8503.13
Subtract 198 from 240 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
66 can be fit into 420 6 times, resulting in a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 8503.136
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
240 divided by 66 is 3 with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 8503.1363
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
420 divided by 66 is 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 8503.13636
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
66 can be fit into 240 3 times, resulting in a remainder of 42.
The next digit of our result is 3. 
Result so far: 8503.136363
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
66 can be fit into 420 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 8503.1363636
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
66 goes into 240 3 times with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 8503.13636363
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 8503.13636363 with a balance of 4.2e-08.
