Let's divide 218831 by 89
The aim is to understand the frequency of 89 in 218831.

Going ahead to step 1:
The number 89 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 89

Let's proceed to step 2:
When dividing 21 by 89, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 89

Moving on to step 3:
89 can be fit into 218 2 times, resulting in a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 178 away from 218, we end up with 40.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 89

Going ahead to step 4:
89 can be fit into 408 4 times, resulting in a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we take 356 away from 408, we end up with 52.
Append the next digit (3) from the dividend to 52 and continue with: 523 / 89

Advancing to step 5:
89 goes into 523 5 times with a remainder of 78.
The next digit of our result is 5. 
Result so far: 245.0
If we take 445 away from 523, we end up with 78.
Bring next digit (1) of the dividend behind the 78 and repeat the process: 781 / 89

On to step 6:
When dividing 781 by 89, we get 8 with a remainder of 69.
Put 8 as the next digit of the answer. 
Result so far: 2458.0
The remainder is 69 after subtracting 712 from 781.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 7:
89 goes into 690 7 times with a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 2458.7
Subtract 623 from 690 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 8:
When dividing 670 by 89, we get 7 with a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 2458.77
If we take 623 away from 670, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final outcome is 2458.77, with a leftover of 0.047.
