88589361 ÷ 260 
The aim is to understand the frequency of 260 in 88589361.

Let's proceed to step 1:
If we divide 8 by 260, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 260

Going ahead to step 2:
260 goes into 88 0 times with a remainder of 88.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 88 leaves us with 88.
Append the next digit (5) from the dividend to 88 and continue with: 885 / 260

Advancing to step 3:
885 divided by 260 is 3 with a remainder of 105.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 780 from 885, we get 105.
Bring next digit (8) of the dividend behind the 105 and repeat the process: 1058 / 260

Let's proceed to step 4:
260 goes into 1058 4 times with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtract 1040 from 1058 to get 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 260

Advancing to step 5:
The number 260 fits into 189 0 times, leaving a remainder of 189.
The number 0 becomes the next digit in our result. 
Result so far: 340.0
The remainder is 189 after subtracting 0 from 189.
Take the next digit (3) from the dividend and append it to 189, then repeat: 1893 / 260

Going ahead to step 6:
1893 divided by 260 is 7 with a remainder of 73.
The next digit of our result is 7. 
Result so far: 3407.0
The remainder is 73 after subtracting 1820 from 1893.
Append the next digit (6) from the dividend to 73 and continue with: 736 / 260

Let's proceed to step 7:
736 divided by 260 is 2 with a remainder of 216.
Put 2 as the next digit of the answer. 
Result so far: 34072.0
If we subtract 520 from 736, we get 216.
Bring next digit (1) of the dividend behind the 216 and repeat the process: 2161 / 260

Going ahead to step 8:
260 goes into 2161 8 times with a remainder of 81.
The number 8 becomes the next digit in our result. 
Result so far: 340728.0
If we take 2080 away from 2161, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 9:
260 can be fit into 810 3 times, resulting in a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 340728.3
If we take 780 away from 810, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
300 divided by 260 is 1 with a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 340728.31
Deduct 260 from 300 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
When dividing 400 by 260, we get 1 with a remainder of 140.
The next digit of our result is 1. 
Result so far: 340728.311
Subtract 260 from 400 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final outcome is 340728.311, with a leftover of 0.014.
