66844760 ÷ 85 
Our goal is to divide 66844760 by 85.

Step 1:
85 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 85

Step 2:
85 can be fit into 66 0 times, resulting in a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Append the next digit (8) from the dividend to 66 and continue with: 668 / 85

Advancing to step 3:
85 goes into 668 7 times with a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 595 from 668 leaves us with 73.
Fetch the next digit (4) from the dividend, attach it to 73 and continue: 734 / 85

Let's proceed to step 4:
734 divided by 85 is 8 with a remainder of 54.
The next digit of our result is 8. 
Result so far: 78.0
The remainder is 54 after subtracting 680 from 734.
Take the next digit (4) from the dividend and append it to 54, then repeat: 544 / 85

Advancing to step 5:
85 can be fit into 544 6 times, resulting in a remainder of 34.
The next digit of our result is 6. 
Result so far: 786.0
If we take 510 away from 544, we end up with 34.
Include the next digit (7) from the dividend after 34, then repeat: 347 / 85

Moving on to step 6:
85 goes into 347 4 times with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 7864.0
Deduct 340 from 347 and we're left with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 85

On to step 7:
76 divided by 85 is 0 with a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 78640.0
Subtracting 0 from 76 leaves us with 76.
Take the next digit (0) from the dividend and append it to 76, then repeat: 760 / 85

Let's proceed to step 8:
If we divide 760 by 85, we get 8 and a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 786408.0
If we subtract 680 from 760, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
800 divided by 85 is 9 with a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 786408.9
The remainder is 35 after subtracting 765 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
If we divide 350 by 85, we get 4 and a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 786408.94
Deduct 340 from 350 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
The number 85 fits into 100 1 times, leaving a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 786408.941
The remainder is 15 after subtracting 85 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
The number 85 fits into 150 1 times, leaving a remainder of 65.
The next digit of our result is 1. 
Result so far: 786408.9411
The remainder is 65 after subtracting 85 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

In conclusion, the division gives 786408.9411 with a balance of 0.00065.
