We're dividing 436142 by 88 
The aim is to understand the frequency of 88 in 436142.

On to step 1:
The number 88 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 88

Advancing to step 2:
88 goes into 43 0 times with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Take the next digit (6) from the dividend and append it to 43, then repeat: 436 / 88

Moving on to step 3:
88 goes into 436 4 times with a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 352 from 436 to get 84.
Include the next digit (1) from the dividend after 84, then repeat: 841 / 88

Moving on to step 4:
The number 88 fits into 841 9 times, leaving a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 49.0
If we take 792 away from 841, we end up with 49.
Append the next digit (4) from the dividend to 49 and continue with: 494 / 88

Advancing to step 5:
494 divided by 88 is 5 with a remainder of 54.
The next digit of our result is 5. 
Result so far: 495.0
Subtracting 440 from 494 leaves us with 54.
Append the next digit (2) from the dividend to 54 and continue with: 542 / 88

Going ahead to step 6:
The number 88 fits into 542 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 4956.0
If we subtract 528 from 542, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
The number 88 fits into 140 1 times, leaving a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 4956.1
If we subtract 88 from 140, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 8:
When dividing 520 by 88, we get 5 with a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 4956.15
Subtracting 440 from 520 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 9:
If we divide 800 by 88, we get 9 and a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 4956.159
The remainder is 8 after subtracting 792 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
80 divided by 88 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 4956.159
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
The number 88 fits into 800 9 times, leaving a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 4956.15909
If we subtract 792 from 800, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
When dividing 80 by 88, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 4956.15909
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
The number 88 fits into 800 9 times, leaving a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 4956.1590909
Subtracting 792 from 800 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
88 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 4956.1590909
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 4956.1590909, with a leftover of 8e-08.
