78448115 divided by 991 
We're looking to find how many times 991 goes into 78448115.

Let's proceed to step 1:
The number 991 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 991

Let's proceed to step 2:
991 goes into 78 0 times with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Bring next digit (4) of the dividend behind the 78 and repeat the process: 784 / 991

Moving on to step 3:
If we divide 784 by 991, we get 0 and a remainder of 784.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 784 after subtracting 0 from 784.
Take the next digit (4) from the dividend and append it to 784, then repeat: 7844 / 991

On to step 4:
When dividing 7844 by 991, we get 7 with a remainder of 907.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 907 after subtracting 6937 from 7844.
Fetch the next digit (8) from the dividend, attach it to 907 and continue: 9078 / 991

Going ahead to step 5:
The number 991 fits into 9078 9 times, leaving a remainder of 159.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Subtracting 8919 from 9078 leaves us with 159.
Grab the next digit (1) from the dividend, add it to 159, then carry on: 1591 / 991

Step 6:
1591 divided by 991 is 1 with a remainder of 600.
The number 1 becomes the next digit in our result. 
Result so far: 791.0
If we take 991 away from 1591, we end up with 600.
Fetch the next digit (1) from the dividend, attach it to 600 and continue: 6001 / 991

Step 7:
991 goes into 6001 6 times with a remainder of 55.
The number 6 becomes the next digit in our result. 
Result so far: 7916.0
Subtract 5946 from 6001 to get 55.
Grab the next digit (5) from the dividend, add it to 55, then carry on: 555 / 991

On to step 8:
The number 991 fits into 555 0 times, leaving a remainder of 555.
The number 0 becomes the next digit in our result. 
Result so far: 79160.0
If we take 0 away from 555, we end up with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

On to step 9:
991 goes into 5550 5 times with a remainder of 595.
The next digit of our result is 5. 
Result so far: 79160.5
If we subtract 4955 from 5550, we get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Advancing to step 10:
If we divide 5950 by 991, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 79160.56
The remainder is 4 after subtracting 5946 from 5950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
When dividing 40 by 991, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 79160.56
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
991 goes into 400 0 times with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 79160.56
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 79160.56, with a leftover of 0.004.
