Our goal is to divide 66475414 by 78.

Going ahead to step 1:
6 divided by 78 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 78

On to step 2:
When dividing 66 by 78, 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 / 78

Moving on to step 3:
When dividing 664 by 78, we get 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 624 from 664 leaves us with 40.
Fetch the next digit (7) from the dividend, attach it to 40 and continue: 407 / 78

Let's proceed to step 4:
If we divide 407 by 78, we get 5 and a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 85.0
Deduct 390 from 407 and we're left with 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 78

Advancing to step 5:
175 divided by 78 is 2 with a remainder of 19.
The next digit of our result is 2. 
Result so far: 852.0
Deduct 156 from 175 and we're left with 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 78

Advancing to step 6:
194 divided by 78 is 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 8522.0
Subtracting 156 from 194 leaves us with 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 78

Step 7:
When dividing 381 by 78, we get 4 with a remainder of 69.
Use 4 as the next digit of our solution. 
Result so far: 85224.0
Deduct 312 from 381 and we're left with 69.
Fetch the next digit (4) from the dividend, attach it to 69 and continue: 694 / 78

On to step 8:
78 can be fit into 694 8 times, resulting in a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 852248.0
If we take 624 away from 694, we end up 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.

Going ahead to step 9:
78 goes into 700 8 times with a remainder of 76.
The next digit of our result is 8. 
Result so far: 852248.8
Deduct 624 from 700 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 10:
78 goes into 760 9 times with a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 852248.89
If we take 702 away from 760, we end up 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.

Moving on to step 11:
78 can be fit into 580 7 times, resulting in a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 852248.897
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 12:
When dividing 340 by 78, we get 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 852248.8974
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
280 divided by 78 is 3 with a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 852248.89743
The remainder is 46 after subtracting 234 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 14:
460 divided by 78 is 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 852248.897435
If we subtract 390 from 460, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 15:
If we divide 700 by 78, we get 8 and a remainder of 76.
The next digit of our result is 8. 
Result so far: 852248.8974358
The remainder is 76 after subtracting 624 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 16:
760 divided by 78 is 9 with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 852248.89743589
If we take 702 away from 760, we end up 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.

In conclusion, the division gives 852248.89743589 with a balance of 5.8e-08.
