88185461 ÷ 129 
The aim is to understand the frequency of 129 in 88185461.

Going ahead to step 1:
The number 129 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 129

Going ahead to step 2:
If we divide 88 by 129, we get 0 and a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 88 and we're left with 88.
Take the next digit (1) from the dividend and append it to 88, then repeat: 881 / 129

On to step 3:
If we divide 881 by 129, we get 6 and a remainder of 107.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 774 from 881, we get 107.
Include the next digit (8) from the dividend after 107, then repeat: 1078 / 129

Moving on to step 4:
129 goes into 1078 8 times with a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 68.0
Subtracting 1032 from 1078 leaves us with 46.
Fetch the next digit (5) from the dividend, attach it to 46 and continue: 465 / 129

Let's proceed to step 5:
465 divided by 129 is 3 with a remainder of 78.
The number 3 becomes the next digit in our result. 
Result so far: 683.0
If we subtract 387 from 465, we get 78.
Fetch the next digit (4) from the dividend, attach it to 78 and continue: 784 / 129

Advancing to step 6:
784 divided by 129 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 6836.0
Subtract 774 from 784 to get 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 129

Going ahead to step 7:
129 can be fit into 106 0 times, resulting in a remainder of 106.
Use 0 as the next digit of our solution. 
Result so far: 68360.0
The remainder is 106 after subtracting 0 from 106.
Append the next digit (1) from the dividend to 106 and continue with: 1061 / 129

Moving on to step 8:
The number 129 fits into 1061 8 times, leaving a remainder of 29.
Write down 8 as next digit of the result. 
Result so far: 683608.0
If we take 1032 away from 1061, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 9:
129 goes into 290 2 times with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 683608.2
If we subtract 258 from 290, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
320 divided by 129 is 2 with a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 683608.22
If we take 258 away from 320, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final result is 683608.22 with a remainder of 0.062.
