87161255 ÷ 529 
The aim is to understand the frequency of 529 in 87161255.

Let's proceed to step 1:
If we divide 8 by 529, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 529

Moving on to step 2:
When dividing 87 by 529, we get 0 with a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 529

Moving on to step 3:
529 can be fit into 871 1 times, resulting in a remainder of 342.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 529 from 871 and we're left with 342.
Include the next digit (6) from the dividend after 342, then repeat: 3426 / 529

Moving on to step 4:
3426 divided by 529 is 6 with a remainder of 252.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 3174 from 3426 leaves us with 252.
Append the next digit (1) from the dividend to 252 and continue with: 2521 / 529

Let's proceed to step 5:
529 can be fit into 2521 4 times, resulting in a remainder of 405.
Write down 4 as next digit of the result. 
Result so far: 164.0
The remainder is 405 after subtracting 2116 from 2521.
Bring next digit (2) of the dividend behind the 405 and repeat the process: 4052 / 529

Step 6:
When dividing 4052 by 529, we get 7 with a remainder of 349.
Use 7 as the next digit of our solution. 
Result so far: 1647.0
The remainder is 349 after subtracting 3703 from 4052.
Append the next digit (5) from the dividend to 349 and continue with: 3495 / 529

Advancing to step 7:
If we divide 3495 by 529, we get 6 and a remainder of 321.
Write down 6 as next digit of the result. 
Result so far: 16476.0
Deduct 3174 from 3495 and we're left with 321.
Take the next digit (5) from the dividend and append it to 321, then repeat: 3215 / 529

Going ahead to step 8:
529 can be fit into 3215 6 times, resulting in a remainder of 41.
Write down 6 as next digit of the result. 
Result so far: 164766.0
Deduct 3174 from 3215 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 9:
410 divided by 529 is 0 with a remainder of 410.
Put 0 as the next digit of the answer. 
Result so far: 164766.0
If we take 0 away from 410, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 10:
The number 529 fits into 4100 7 times, leaving a remainder of 397.
Use 7 as the next digit of our solution. 
Result so far: 164766.07
Subtract 3703 from 4100 to get 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Let's proceed to step 11:
If we divide 3970 by 529, we get 7 and a remainder of 267.
Use 7 as the next digit of our solution. 
Result so far: 164766.077
Subtracting 3703 from 3970 leaves us with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

The final result is 164766.077 with a remainder of 0.0267.
