66717257 ÷ 566 
We want to divide 66717257 by 566.

Moving on to step 1:
6 divided by 566 is 0 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.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 566

On to step 2:
When dividing 66 by 566, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (7) from the dividend after 66, then repeat: 667 / 566

Advancing to step 3:
When dividing 667 by 566, we get 1 with a remainder of 101.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 566 from 667 and we're left with 101.
Append the next digit (1) from the dividend to 101 and continue with: 1011 / 566

Going ahead to step 4:
1011 divided by 566 is 1 with a remainder of 445.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 566 from 1011 to get 445.
Bring next digit (7) of the dividend behind the 445 and repeat the process: 4457 / 566

Moving on to step 5:
566 goes into 4457 7 times with a remainder of 495.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
If we subtract 3962 from 4457, we get 495.
Fetch the next digit (2) from the dividend, attach it to 495 and continue: 4952 / 566

On to step 6:
The number 566 fits into 4952 8 times, leaving a remainder of 424.
Record the quotient 8 as the next digit in the result. 
Result so far: 1178.0
Subtract 4528 from 4952 to get 424.
Take the next digit (5) from the dividend and append it to 424, then repeat: 4245 / 566

On to step 7:
If we divide 4245 by 566, we get 7 and a remainder of 283.
Record the quotient 7 as the next digit in the result. 
Result so far: 11787.0
Subtracting 3962 from 4245 leaves us with 283.
Take the next digit (7) from the dividend and append it to 283, then repeat: 2837 / 566

Let's proceed to step 8:
If we divide 2837 by 566, we get 5 and a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 117875.0
The remainder is 7 after subtracting 2830 from 2837.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
70 divided by 566 is 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 117875.0
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
If we divide 700 by 566, we get 1 and a remainder of 134.
Write down 1 as next digit of the result. 
Result so far: 117875.01
If we subtract 566 from 700, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 11:
566 goes into 1340 2 times with a remainder of 208.
The next digit of our result is 2. 
Result so far: 117875.012
Deduct 1132 from 1340 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 12:
566 goes into 2080 3 times with a remainder of 382.
The next digit of our result is 3. 
Result so far: 117875.0123
If we subtract 1698 from 2080, we get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Step 13:
566 can be fit into 3820 6 times, resulting in a remainder of 424.
Record the quotient 6 as the next digit in the result. 
Result so far: 117875.01236
If we subtract 3396 from 3820, we get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Let's proceed to step 14:
566 goes into 4240 7 times with a remainder of 278.
The next digit of our result is 7. 
Result so far: 117875.012367
Subtract 3962 from 4240 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Moving on to step 15:
566 can be fit into 2780 4 times, resulting in a remainder of 516.
Write down 4 as next digit of the result. 
Result so far: 117875.0123674
Subtracting 2264 from 2780 leaves us with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 16:
When dividing 5160 by 566, we get 9 with a remainder of 66.
Write down 9 as next digit of the result. 
Result so far: 117875.01236749
Subtract 5094 from 5160 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

In conclusion, the division gives 117875.01236749 with a balance of 6.6e-08.
