88565899 ÷ 175 
The aim is to understand the frequency of 175 in 88565899.

Going ahead to step 1:
If we divide 8 by 175, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 175

Moving on to step 2:
When dividing 88 by 175, we get 0 with a remainder of 88.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 88, we get 88.
Fetch the next digit (5) from the dividend, attach it to 88 and continue: 885 / 175

Advancing to step 3:
The number 175 fits into 885 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 875 from 885, we get 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 175

Advancing to step 4:
The number 175 fits into 106 0 times, leaving a remainder of 106.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Deduct 0 from 106 and we're left with 106.
Bring next digit (5) of the dividend behind the 106 and repeat the process: 1065 / 175

Step 5:
If we divide 1065 by 175, we get 6 and a remainder of 15.
The next digit of our result is 6. 
Result so far: 506.0
Subtract 1050 from 1065 to get 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 175

Moving on to step 6:
If we divide 158 by 175, we get 0 and a remainder of 158.
The number 0 becomes the next digit in our result. 
Result so far: 5060.0
Subtracting 0 from 158 leaves us with 158.
Bring next digit (9) of the dividend behind the 158 and repeat the process: 1589 / 175

Let's proceed to step 7:
When dividing 1589 by 175, we get 9 with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 50609.0
Subtracting 1575 from 1589 leaves us with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 175

Advancing to step 8:
175 can be fit into 149 0 times, resulting in a remainder of 149.
The next digit of our result is 0. 
Result so far: 506090.0
Subtracting 0 from 149 leaves us with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Step 9:
175 can be fit into 1490 8 times, resulting in a remainder of 90.
Put 8 as the next digit of the answer. 
Result so far: 506090.8
Subtracting 1400 from 1490 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
175 can be fit into 900 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 506090.85
The remainder is 25 after subtracting 875 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
250 divided by 175 is 1 with a remainder of 75.
The next digit of our result is 1. 
Result so far: 506090.851
The remainder is 75 after subtracting 175 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 12:
The number 175 fits into 750 4 times, leaving a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 506090.8514
If we take 700 away from 750, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
175 can be fit into 500 2 times, resulting in a remainder of 150.
The number 2 becomes the next digit in our result. 
Result so far: 506090.85142
Subtracting 350 from 500 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 14:
1500 divided by 175 is 8 with a remainder of 100.
Put 8 as the next digit of the answer. 
Result so far: 506090.851428
Deduct 1400 from 1500 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 15:
175 can be fit into 1000 5 times, resulting in a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 506090.8514285
The remainder is 125 after subtracting 875 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 16:
175 goes into 1250 7 times with a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 506090.85142857
Deduct 1225 from 1250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 506090.85142857 and a remainder of 2.5e-08.
