We look at the division of 87158208 by 260 
The aim is to understand the frequency of 260 in 87158208.

Going ahead to step 1:
260 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 260

Let's proceed to step 2:
The number 260 fits into 87 0 times, leaving a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Take the next digit (1) from the dividend and append it to 87, then repeat: 871 / 260

On to step 3:
When dividing 871 by 260, we get 3 with a remainder of 91.
The next digit of our result is 3. 
Result so far: 3.0
If we take 780 away from 871, we end up with 91.
Include the next digit (5) from the dividend after 91, then repeat: 915 / 260

Let's proceed to step 4:
If we divide 915 by 260, we get 3 and a remainder of 135.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Deduct 780 from 915 and we're left with 135.
Take the next digit (8) from the dividend and append it to 135, then repeat: 1358 / 260

Moving on to step 5:
If we divide 1358 by 260, we get 5 and a remainder of 58.
Use 5 as the next digit of our solution. 
Result so far: 335.0
If we take 1300 away from 1358, we end up with 58.
Grab the next digit (2) from the dividend, add it to 58, then carry on: 582 / 260

Let's proceed to step 6:
260 can be fit into 582 2 times, resulting in a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 3352.0
Subtracting 520 from 582 leaves us with 62.
Bring next digit (0) of the dividend behind the 62 and repeat the process: 620 / 260

Advancing to step 7:
If we divide 620 by 260, we get 2 and a remainder of 100.
Record the quotient 2 as the next digit in the result. 
Result so far: 33522.0
The remainder is 100 after subtracting 520 from 620.
Include the next digit (8) from the dividend after 100, then repeat: 1008 / 260

Advancing to step 8:
260 goes into 1008 3 times with a remainder of 228.
Put 3 as the next digit of the answer. 
Result so far: 335223.0
If we subtract 780 from 1008, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 9:
260 goes into 2280 8 times with a remainder of 200.
The next digit of our result is 8. 
Result so far: 335223.8
Deduct 2080 from 2280 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 10:
260 goes into 2000 7 times with a remainder of 180.
The next digit of our result is 7. 
Result so far: 335223.87
The remainder is 180 after subtracting 1820 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 11:
If we divide 1800 by 260, we get 6 and a remainder of 240.
Record the quotient 6 as the next digit in the result. 
Result so far: 335223.876
Subtracting 1560 from 1800 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 12:
When dividing 2400 by 260, we get 9 with a remainder of 60.
Put 9 as the next digit of the answer. 
Result so far: 335223.8769
Subtract 2340 from 2400 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
260 goes into 600 2 times with a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 335223.87692
Deduct 520 from 600 and we're left 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.

Advancing to step 14:
260 goes into 800 3 times with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 335223.876923
If we take 780 away from 800, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 15:
200 divided by 260 is 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 335223.876923
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 16:
The number 260 fits into 2000 7 times, leaving a remainder of 180.
Record the quotient 7 as the next digit in the result. 
Result so far: 335223.87692307
The remainder is 180 after subtracting 1820 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

In conclusion, the division gives 335223.87692307 with a balance of 1.8e-07.
