We divide 88814853 by 991
The aim is to understand the frequency of 991 in 88814853.

Moving on to step 1:
991 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 991

Step 2:
When dividing 88 by 991, we get 0 with a remainder of 88.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 88 leaves us with 88.
Fetch the next digit (8) from the dividend, attach it to 88 and continue: 888 / 991

Going ahead to step 3:
The number 991 fits into 888 0 times, leaving a remainder of 888.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 888, we end up with 888.
Include the next digit (1) from the dividend after 888, then repeat: 8881 / 991

Moving on to step 4:
991 goes into 8881 8 times with a remainder of 953.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 7928 away from 8881, we end up with 953.
Bring next digit (4) of the dividend behind the 953 and repeat the process: 9534 / 991

Advancing to step 5:
991 goes into 9534 9 times with a remainder of 615.
Put 9 as the next digit of the answer. 
Result so far: 89.0
Deduct 8919 from 9534 and we're left with 615.
Bring next digit (8) of the dividend behind the 615 and repeat the process: 6158 / 991

On to step 6:
991 can be fit into 6158 6 times, resulting in a remainder of 212.
The next digit of our result is 6. 
Result so far: 896.0
Subtracting 5946 from 6158 leaves us with 212.
Take the next digit (5) from the dividend and append it to 212, then repeat: 2125 / 991

Let's proceed to step 7:
2125 divided by 991 is 2 with a remainder of 143.
The next digit of our result is 2. 
Result so far: 8962.0
The remainder is 143 after subtracting 1982 from 2125.
Append the next digit (3) from the dividend to 143 and continue with: 1433 / 991

Step 8:
When dividing 1433 by 991, we get 1 with a remainder of 442.
The next digit of our result is 1. 
Result so far: 89621.0
The remainder is 442 after subtracting 991 from 1433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Advancing to step 9:
When dividing 4420 by 991, we get 4 with a remainder of 456.
Write down 4 as next digit of the result. 
Result so far: 89621.4
Deduct 3964 from 4420 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

On to step 10:
991 can be fit into 4560 4 times, resulting in a remainder of 596.
The number 4 becomes the next digit in our result. 
Result so far: 89621.44
Subtracting 3964 from 4560 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Our division results in 89621.44 with a remaining 0.596.
