66151 divided by 78 
We're looking to find how many times 78 goes into 66151.

On to step 1:
78 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 78

Going ahead to step 2:
If we divide 66 by 78, we get 0 and a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 78

On to step 3:
661 divided by 78 is 8 with a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 624 from 661 leaves us with 37.
Take the next digit (5) from the dividend and append it to 37, then repeat: 375 / 78

Step 4:
The number 78 fits into 375 4 times, leaving a remainder of 63.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
The remainder is 63 after subtracting 312 from 375.
Append the next digit (1) from the dividend to 63 and continue with: 631 / 78

Moving on to step 5:
78 can be fit into 631 8 times, resulting in a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 848.0
If we take 624 away from 631, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 6:
When dividing 70 by 78, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 848.0
Subtract 0 from 70 to 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.

Going ahead to step 7:
78 can be fit into 700 8 times, resulting in a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 848.08
Subtracting 624 from 700 leaves us 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 8:
The number 78 fits into 760 9 times, leaving a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 848.089
The remainder is 58 after subtracting 702 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 9:
78 can be fit into 580 7 times, resulting in a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 848.0897
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
78 goes into 340 4 times with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 848.08974
If we take 312 away from 340, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
The number 78 fits into 280 3 times, leaving a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 848.089743
Subtract 234 from 280 to get 46.
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 12:
If we divide 460 by 78, we get 5 and a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 848.0897435
The remainder is 70 after subtracting 390 from 460.
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 13:
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: 848.08974358
Subtracting 624 from 700 leaves us 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.

The final result is 848.08974358 with a remainder of 7.6e-08.
