We look at the division of 66418594 by 307 
We're looking to find how many times 307 goes into 66418594.

Moving on to step 1:
The number 307 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 307

Step 2:
When dividing 66 by 307, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Append the next digit (4) from the dividend to 66 and continue with: 664 / 307

Let's proceed to step 3:
664 divided by 307 is 2 with a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 614 from 664 and we're left with 50.
Take the next digit (1) from the dividend and append it to 50, then repeat: 501 / 307

Advancing to step 4:
501 divided by 307 is 1 with a remainder of 194.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtracting 307 from 501 leaves us with 194.
Fetch the next digit (8) from the dividend, attach it to 194 and continue: 1948 / 307

On to step 5:
307 can be fit into 1948 6 times, resulting in a remainder of 106.
Record the quotient 6 as the next digit in the result. 
Result so far: 216.0
Subtract 1842 from 1948 to get 106.
Fetch the next digit (5) from the dividend, attach it to 106 and continue: 1065 / 307

Going ahead to step 6:
The number 307 fits into 1065 3 times, leaving a remainder of 144.
The number 3 becomes the next digit in our result. 
Result so far: 2163.0
Deduct 921 from 1065 and we're left with 144.
Fetch the next digit (9) from the dividend, attach it to 144 and continue: 1449 / 307

Step 7:
When dividing 1449 by 307, we get 4 with a remainder of 221.
Write down 4 as next digit of the result. 
Result so far: 21634.0
Subtract 1228 from 1449 to get 221.
Fetch the next digit (4) from the dividend, attach it to 221 and continue: 2214 / 307

Moving on to step 8:
307 goes into 2214 7 times with a remainder of 65.
The number 7 becomes the next digit in our result. 
Result so far: 216347.0
If we subtract 2149 from 2214, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 9:
307 can be fit into 650 2 times, resulting in a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 216347.2
Subtract 614 from 650 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
If we divide 360 by 307, we get 1 and a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 216347.21
If we take 307 away from 360, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 11:
307 goes into 530 1 times with a remainder of 223.
Write down 1 as next digit of the result. 
Result so far: 216347.211
Subtracting 307 from 530 leaves us with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

In conclusion, the division gives 216347.211 with a balance of 0.0223.
