We look at the division of 144591 by 88 
The aim is to understand the frequency of 88 in 144591.

On to step 1:
88 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 88

Let's proceed to step 2:
If we divide 14 by 88, we get 0 and a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Grab the next digit (4) from the dividend, add it to 14, then carry on: 144 / 88

Step 3:
The number 88 fits into 144 1 times, leaving a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 88 from 144 and we're left with 56.
Fetch the next digit (5) from the dividend, attach it to 56 and continue: 565 / 88

Advancing to step 4:
88 goes into 565 6 times with a remainder of 37.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 37 after subtracting 528 from 565.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 88

Moving on to step 5:
If we divide 379 by 88, we get 4 and a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
Subtracting 352 from 379 leaves us with 27.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 88

Advancing to step 6:
The number 88 fits into 271 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 1643.0
The remainder is 7 after subtracting 264 from 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
88 can be fit into 70 0 times, resulting in a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 1643.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
If we divide 700 by 88, we get 7 and a remainder of 84.
The number 7 becomes the next digit in our result. 
Result so far: 1643.07
If we subtract 616 from 700, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 9:
88 can be fit into 840 9 times, resulting in a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 1643.079
Subtract 792 from 840 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
480 divided by 88 is 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 1643.0795
Subtracting 440 from 480 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
88 goes into 400 4 times with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 1643.07954
The remainder is 48 after subtracting 352 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
480 divided by 88 is 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 1643.079545
Deduct 440 from 480 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
The number 88 fits into 400 4 times, leaving a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 1643.0795454
Subtracting 352 from 400 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 14:
When dividing 480 by 88, we get 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 1643.07954545
If we subtract 440 from 480, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 1643.07954545 with a remaining 4e-08.
