We look at the division of 76513474 by 991 
The aim is to understand the frequency of 991 in 76513474.

Step 1:
991 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 991

Moving on to step 2:
When dividing 76 by 991, we get 0 with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Bring next digit (5) of the dividend behind the 76 and repeat the process: 765 / 991

Going ahead to step 3:
If we divide 765 by 991, we get 0 and a remainder of 765.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 765 leaves us with 765.
Include the next digit (1) from the dividend after 765, then repeat: 7651 / 991

Advancing to step 4:
7651 divided by 991 is 7 with a remainder of 714.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 6937 from 7651, we get 714.
Grab the next digit (3) from the dividend, add it to 714, then carry on: 7143 / 991

Going ahead to step 5:
991 can be fit into 7143 7 times, resulting in a remainder of 206.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Subtracting 6937 from 7143 leaves us with 206.
Grab the next digit (4) from the dividend, add it to 206, then carry on: 2064 / 991

Advancing to step 6:
The number 991 fits into 2064 2 times, leaving a remainder of 82.
The number 2 becomes the next digit in our result. 
Result so far: 772.0
Subtract 1982 from 2064 to get 82.
Grab the next digit (7) from the dividend, add it to 82, then carry on: 827 / 991

Going ahead to step 7:
991 can be fit into 827 0 times, resulting in a remainder of 827.
Record the quotient 0 as the next digit in the result. 
Result so far: 7720.0
If we subtract 0 from 827, we get 827.
Fetch the next digit (4) from the dividend, attach it to 827 and continue: 8274 / 991

Going ahead to step 8:
When dividing 8274 by 991, we get 8 with a remainder of 346.
Put 8 as the next digit of the answer. 
Result so far: 77208.0
If we take 7928 away from 8274, we end up with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Let's proceed to step 9:
If we divide 3460 by 991, we get 3 and a remainder of 487.
Use 3 as the next digit of our solution. 
Result so far: 77208.3
Subtracting 2973 from 3460 leaves us with 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Let's proceed to step 10:
991 can be fit into 4870 4 times, resulting in a remainder of 906.
Record the quotient 4 as the next digit in the result. 
Result so far: 77208.34
If we take 3964 away from 4870, we end up with 906.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9060, and continue the process.

On to step 11:
9060 divided by 991 is 9 with a remainder of 141.
Write down 9 as next digit of the result. 
Result so far: 77208.349
Subtract 8919 from 9060 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Let's proceed to step 12:
1410 divided by 991 is 1 with a remainder of 419.
The number 1 becomes the next digit in our result. 
Result so far: 77208.3491
Deduct 991 from 1410 and we're left with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Step 13:
When dividing 4190 by 991, we get 4 with a remainder of 226.
The next digit of our result is 4. 
Result so far: 77208.34914
If we subtract 3964 from 4190, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 14:
991 goes into 2260 2 times with a remainder of 278.
Write down 2 as next digit of the result. 
Result so far: 77208.349142
Deduct 1982 from 2260 and we're left with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 15:
991 can be fit into 2780 2 times, resulting in a remainder of 798.
Use 2 as the next digit of our solution. 
Result so far: 77208.3491422
The remainder is 798 after subtracting 1982 from 2780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Our division results in 77208.3491422 with a remaining 7.98e-06.
