66116725 ÷ 618 
We want to divide 66116725 by 618.

Going ahead to step 1:
If we divide 6 by 618, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 618

Let's proceed to step 2:
66 divided by 618 is 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 618

Let's proceed to step 3:
618 goes into 661 1 times with a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 618 from 661 leaves us with 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 618

Advancing to step 4:
431 divided by 618 is 0 with a remainder of 431.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 431 and we're left with 431.
Append the next digit (6) from the dividend to 431 and continue with: 4316 / 618

Advancing to step 5:
If we divide 4316 by 618, we get 6 and a remainder of 608.
Write down 6 as next digit of the result. 
Result so far: 106.0
Subtracting 3708 from 4316 leaves us with 608.
Append the next digit (7) from the dividend to 608 and continue with: 6087 / 618

Going ahead to step 6:
When dividing 6087 by 618, we get 9 with a remainder of 525.
Use 9 as the next digit of our solution. 
Result so far: 1069.0
If we take 5562 away from 6087, we end up with 525.
Fetch the next digit (2) from the dividend, attach it to 525 and continue: 5252 / 618

Advancing to step 7:
618 goes into 5252 8 times with a remainder of 308.
Record the quotient 8 as the next digit in the result. 
Result so far: 10698.0
If we subtract 4944 from 5252, we get 308.
Append the next digit (5) from the dividend to 308 and continue with: 3085 / 618

Let's proceed to step 8:
If we divide 3085 by 618, we get 4 and a remainder of 613.
The next digit of our result is 4. 
Result so far: 106984.0
If we take 2472 away from 3085, we end up with 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

On to step 9:
If we divide 6130 by 618, we get 9 and a remainder of 568.
The next digit of our result is 9. 
Result so far: 106984.9
Deduct 5562 from 6130 and we're left with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Going ahead to step 10:
618 can be fit into 5680 9 times, resulting in a remainder of 118.
Put 9 as the next digit of the answer. 
Result so far: 106984.99
The remainder is 118 after subtracting 5562 from 5680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

In conclusion, the division gives 106984.99 with a balance of 0.118.
