Let's divide 619660 by 66
We're looking to find how many times 66 goes into 619660.

Step 1:
66 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 66

Advancing to step 2:
When dividing 61 by 66, we get 0 with a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Include the next digit (9) from the dividend after 61, then repeat: 619 / 66

Let's proceed to step 3:
66 can be fit into 619 9 times, resulting in a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 594 away from 619, we end up with 25.
Take the next digit (6) from the dividend and append it to 25, then repeat: 256 / 66

Advancing to step 4:
66 goes into 256 3 times with a remainder of 58.
Use 3 as the next digit of our solution. 
Result so far: 93.0
The remainder is 58 after subtracting 198 from 256.
Take the next digit (6) from the dividend and append it to 58, then repeat: 586 / 66

Advancing to step 5:
66 can be fit into 586 8 times, resulting in a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 938.0
Subtract 528 from 586 to get 58.
Include the next digit (0) from the dividend after 58, then repeat: 580 / 66

On to step 6:
580 divided by 66 is 8 with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 9388.0
If we subtract 528 from 580, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 7:
The number 66 fits into 520 7 times, leaving a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 9388.7
The remainder is 58 after subtracting 462 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 8:
The number 66 fits into 580 8 times, leaving a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 9388.78
If we subtract 528 from 580, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
66 goes into 520 7 times with a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 9388.787
Deduct 462 from 520 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
66 goes into 580 8 times with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 9388.7878
Deduct 528 from 580 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
The number 66 fits into 520 7 times, leaving a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 9388.78787
Subtracting 462 from 520 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 12:
66 can be fit into 580 8 times, resulting in a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 9388.787878
Subtract 528 from 580 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 13:
66 goes into 520 7 times with a remainder of 58.
The next digit of our result is 7. 
Result so far: 9388.7878787
If we subtract 462 from 520, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 14:
The number 66 fits into 580 8 times, leaving a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 9388.78787878
If we subtract 528 from 580, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

In conclusion, the division gives 9388.78787878 with a balance of 5.2e-08.
