We look at the division of 87079315 by 261 
The aim is to understand the frequency of 261 in 87079315.

Going ahead to step 1:
If we divide 8 by 261, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 261

Advancing to step 2:
The number 261 fits into 87 0 times, leaving a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Grab the next digit (0) from the dividend, add it to 87, then carry on: 870 / 261

Step 3:
870 divided by 261 is 3 with a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 783 from 870 to get 87.
Take the next digit (7) from the dividend and append it to 87, then repeat: 877 / 261

Step 4:
The number 261 fits into 877 3 times, leaving a remainder of 94.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Deduct 783 from 877 and we're left with 94.
Append the next digit (9) from the dividend to 94 and continue with: 949 / 261

Let's proceed to step 5:
The number 261 fits into 949 3 times, leaving a remainder of 166.
Record the quotient 3 as the next digit in the result. 
Result so far: 333.0
If we take 783 away from 949, we end up with 166.
Take the next digit (3) from the dividend and append it to 166, then repeat: 1663 / 261

Let's proceed to step 6:
When dividing 1663 by 261, we get 6 with a remainder of 97.
The number 6 becomes the next digit in our result. 
Result so far: 3336.0
If we take 1566 away from 1663, we end up with 97.
Fetch the next digit (1) from the dividend, attach it to 97 and continue: 971 / 261

Advancing to step 7:
261 can be fit into 971 3 times, resulting in a remainder of 188.
The number 3 becomes the next digit in our result. 
Result so far: 33363.0
The remainder is 188 after subtracting 783 from 971.
Fetch the next digit (5) from the dividend, attach it to 188 and continue: 1885 / 261

Let's proceed to step 8:
The number 261 fits into 1885 7 times, leaving a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 333637.0
If we subtract 1827 from 1885, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 9:
261 can be fit into 580 2 times, resulting in a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 333637.2
Subtracting 522 from 580 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 10:
The number 261 fits into 580 2 times, leaving a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 333637.22
Subtract 522 from 580 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

After the division, we end up with 333637.22 and a remainder of 0.058.
