We're dividing 88791855 by 331 
The aim is to understand the frequency of 331 in 88791855.

Going ahead to step 1:
The number 331 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 331

Going ahead to step 2:
The number 331 fits into 88 0 times, leaving a remainder of 88.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Bring next digit (7) of the dividend behind the 88 and repeat the process: 887 / 331

On to step 3:
331 can be fit into 887 2 times, resulting in a remainder of 225.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 662 from 887 to get 225.
Grab the next digit (9) from the dividend, add it to 225, then carry on: 2259 / 331

On to step 4:
The number 331 fits into 2259 6 times, leaving a remainder of 273.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
The remainder is 273 after subtracting 1986 from 2259.
Fetch the next digit (1) from the dividend, attach it to 273 and continue: 2731 / 331

Going ahead to step 5:
331 goes into 2731 8 times with a remainder of 83.
The number 8 becomes the next digit in our result. 
Result so far: 268.0
If we take 2648 away from 2731, we end up with 83.
Bring next digit (8) of the dividend behind the 83 and repeat the process: 838 / 331

Advancing to step 6:
838 divided by 331 is 2 with a remainder of 176.
Put 2 as the next digit of the answer. 
Result so far: 2682.0
Deduct 662 from 838 and we're left with 176.
Include the next digit (5) from the dividend after 176, then repeat: 1765 / 331

On to step 7:
When dividing 1765 by 331, we get 5 with a remainder of 110.
Write down 5 as next digit of the result. 
Result so far: 26825.0
If we take 1655 away from 1765, we end up with 110.
Take the next digit (5) from the dividend and append it to 110, then repeat: 1105 / 331

Moving on to step 8:
When dividing 1105 by 331, we get 3 with a remainder of 112.
Put 3 as the next digit of the answer. 
Result so far: 268253.0
If we subtract 993 from 1105, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 9:
The number 331 fits into 1120 3 times, leaving a remainder of 127.
Record the quotient 3 as the next digit in the result. 
Result so far: 268253.3
Subtract 993 from 1120 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Advancing to step 10:
331 goes into 1270 3 times with a remainder of 277.
The number 3 becomes the next digit in our result. 
Result so far: 268253.33
If we subtract 993 from 1270, we get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

The final outcome is 268253.33, with a leftover of 0.277.
