We look at the division of 371820 by 88 
The aim is to understand the frequency of 88 in 371820.

Step 1:
The number 88 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 88

Advancing to step 2:
If we divide 37 by 88, we get 0 and a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Fetch the next digit (1) from the dividend, attach it to 37 and continue: 371 / 88

Advancing to step 3:
88 goes into 371 4 times with a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 352 from 371 leaves us with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 88

Going ahead to step 4:
The number 88 fits into 198 2 times, leaving a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Deduct 176 from 198 and we're left with 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 88

Going ahead to step 5:
222 divided by 88 is 2 with a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 422.0
If we subtract 176 from 222, we get 46.
Include the next digit (0) from the dividend after 46, then repeat: 460 / 88

On to step 6:
The number 88 fits into 460 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 4225.0
The remainder is 20 after subtracting 440 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
88 goes into 200 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 4225.2
If we take 176 away from 200, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
88 goes into 240 2 times with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 4225.22
Deduct 176 from 240 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 4225.22 with a balance of 0.064.
