We look at the division of 16002881 by 260 
The aim is to understand the frequency of 260 in 16002881.

On to step 1:
The number 260 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 260

Advancing to step 2:
260 goes into 16 0 times with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 260

Advancing to step 3:
The number 260 fits into 160 0 times, leaving a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 160 and we're left with 160.
Append the next digit (0) from the dividend to 160 and continue with: 1600 / 260

Advancing to step 4:
If we divide 1600 by 260, we get 6 and a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 1560 from 1600 to get 40.
Grab the next digit (2) from the dividend, add it to 40, then carry on: 402 / 260

Advancing to step 5:
When dividing 402 by 260, we get 1 with a remainder of 142.
Write down 1 as next digit of the result. 
Result so far: 61.0
The remainder is 142 after subtracting 260 from 402.
Fetch the next digit (8) from the dividend, attach it to 142 and continue: 1428 / 260

Advancing to step 6:
260 can be fit into 1428 5 times, resulting in a remainder of 128.
Record the quotient 5 as the next digit in the result. 
Result so far: 615.0
Deduct 1300 from 1428 and we're left with 128.
Fetch the next digit (8) from the dividend, attach it to 128 and continue: 1288 / 260

Going ahead to step 7:
260 goes into 1288 4 times with a remainder of 248.
Record the quotient 4 as the next digit in the result. 
Result so far: 6154.0
Deduct 1040 from 1288 and we're left with 248.
Take the next digit (1) from the dividend and append it to 248, then repeat: 2481 / 260

Advancing to step 8:
260 goes into 2481 9 times with a remainder of 141.
The number 9 becomes the next digit in our result. 
Result so far: 61549.0
Subtract 2340 from 2481 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Moving on to step 9:
The number 260 fits into 1410 5 times, leaving a remainder of 110.
Put 5 as the next digit of the answer. 
Result so far: 61549.5
If we take 1300 away from 1410, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 10:
The number 260 fits into 1100 4 times, leaving a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 61549.54
Subtracting 1040 from 1100 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 11:
If we divide 600 by 260, we get 2 and a remainder of 80.
The next digit of our result is 2. 
Result so far: 61549.542
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.

Going ahead to step 12:
If we divide 800 by 260, we get 3 and a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 61549.5423
If we subtract 780 from 800, we get 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 13:
200 divided by 260 is 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 61549.5423
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 14:
When dividing 2000 by 260, we get 7 with a remainder of 180.
Record the quotient 7 as the next digit in the result. 
Result so far: 61549.542307
Deduct 1820 from 2000 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 15:
260 can be fit into 1800 6 times, resulting in a remainder of 240.
The next digit of our result is 6. 
Result so far: 61549.5423076
If we take 1560 away from 1800, we end up 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.

On to step 16:
260 can be fit into 2400 9 times, resulting in a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 61549.54230769
Subtracting 2340 from 2400 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 61549.54230769, with a leftover of 6e-08.
