78176444 divided by 991 
We want to figure out the number of times 78176444 can be divided by 991.

Advancing to step 1:
If we divide 7 by 991, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 991

Let's proceed to step 2:
78 divided by 991 is 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Append the next digit (1) from the dividend to 78 and continue with: 781 / 991

On to step 3:
781 divided by 991 is 0 with a remainder of 781.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 781 to get 781.
Bring next digit (7) of the dividend behind the 781 and repeat the process: 7817 / 991

Step 4:
The number 991 fits into 7817 7 times, leaving a remainder of 880.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 6937 from 7817 to get 880.
Include the next digit (6) from the dividend after 880, then repeat: 8806 / 991

Step 5:
991 goes into 8806 8 times with a remainder of 878.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
If we subtract 7928 from 8806, we get 878.
Take the next digit (4) from the dividend and append it to 878, then repeat: 8784 / 991

Let's proceed to step 6:
991 goes into 8784 8 times with a remainder of 856.
Put 8 as the next digit of the answer. 
Result so far: 788.0
Deduct 7928 from 8784 and we're left with 856.
Take the next digit (4) from the dividend and append it to 856, then repeat: 8564 / 991

Moving on to step 7:
991 goes into 8564 8 times with a remainder of 636.
The number 8 becomes the next digit in our result. 
Result so far: 7888.0
The remainder is 636 after subtracting 7928 from 8564.
Append the next digit (4) from the dividend to 636 and continue with: 6364 / 991

Step 8:
If we divide 6364 by 991, we get 6 and a remainder of 418.
Write down 6 as next digit of the result. 
Result so far: 78886.0
Subtract 5946 from 6364 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Advancing to step 9:
The number 991 fits into 4180 4 times, leaving a remainder of 216.
Record the quotient 4 as the next digit in the result. 
Result so far: 78886.4
If we subtract 3964 from 4180, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 10:
If we divide 2160 by 991, we get 2 and a remainder of 178.
Write down 2 as next digit of the result. 
Result so far: 78886.42
The remainder is 178 after subtracting 1982 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 11:
The number 991 fits into 1780 1 times, leaving a remainder of 789.
Use 1 as the next digit of our solution. 
Result so far: 78886.421
Subtracting 991 from 1780 leaves us with 789.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7890, and continue the process.

Advancing to step 12:
If we divide 7890 by 991, we get 7 and a remainder of 953.
Record the quotient 7 as the next digit in the result. 
Result so far: 78886.4217
Subtracting 6937 from 7890 leaves us with 953.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9530, and continue the process.

Let's proceed to step 13:
The number 991 fits into 9530 9 times, leaving a remainder of 611.
Record the quotient 9 as the next digit in the result. 
Result so far: 78886.42179
Subtract 8919 from 9530 to get 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

Going ahead to step 14:
991 can be fit into 6110 6 times, resulting in a remainder of 164.
The number 6 becomes the next digit in our result. 
Result so far: 78886.421796
Deduct 5946 from 6110 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 15:
When dividing 1640 by 991, we get 1 with a remainder of 649.
Put 1 as the next digit of the answer. 
Result so far: 78886.4217961
Subtracting 991 from 1640 leaves us with 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

Advancing to step 16:
991 goes into 6490 6 times with a remainder of 544.
The number 6 becomes the next digit in our result. 
Result so far: 78886.42179616
The remainder is 544 after subtracting 5946 from 6490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

In conclusion, the division gives 78886.42179616 with a balance of 5.44e-07.
