We look at the division of 16577142 by 260 
The aim is to understand the frequency of 260 in 16577142.

Advancing to step 1:
260 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 260

Advancing to step 2:
If we divide 16 by 260, we get 0 and a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 260

Step 3:
260 goes into 165 0 times with a remainder of 165.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 165 leaves us with 165.
Fetch the next digit (7) from the dividend, attach it to 165 and continue: 1657 / 260

On to step 4:
When dividing 1657 by 260, we get 6 with a remainder of 97.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 97 after subtracting 1560 from 1657.
Fetch the next digit (7) from the dividend, attach it to 97 and continue: 977 / 260

Step 5:
When dividing 977 by 260, we get 3 with a remainder of 197.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
If we subtract 780 from 977, we get 197.
Take the next digit (1) from the dividend and append it to 197, then repeat: 1971 / 260

On to step 6:
If we divide 1971 by 260, we get 7 and a remainder of 151.
Record the quotient 7 as the next digit in the result. 
Result so far: 637.0
Subtract 1820 from 1971 to get 151.
Append the next digit (4) from the dividend to 151 and continue with: 1514 / 260

Going ahead to step 7:
260 can be fit into 1514 5 times, resulting in a remainder of 214.
Put 5 as the next digit of the answer. 
Result so far: 6375.0
Deduct 1300 from 1514 and we're left with 214.
Fetch the next digit (2) from the dividend, attach it to 214 and continue: 2142 / 260

Let's proceed to step 8:
If we divide 2142 by 260, we get 8 and a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 63758.0
Subtracting 2080 from 2142 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 9:
The number 260 fits into 620 2 times, leaving a remainder of 100.
The number 2 becomes the next digit in our result. 
Result so far: 63758.2
If we take 520 away from 620, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 10:
If we divide 1000 by 260, we get 3 and a remainder of 220.
The next digit of our result is 3. 
Result so far: 63758.23
Subtracting 780 from 1000 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 11:
2200 divided by 260 is 8 with a remainder of 120.
Write down 8 as next digit of the result. 
Result so far: 63758.238
Deduct 2080 from 2200 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 12:
The number 260 fits into 1200 4 times, leaving a remainder of 160.
Record the quotient 4 as the next digit in the result. 
Result so far: 63758.2384
Deduct 1040 from 1200 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 13:
1600 divided by 260 is 6 with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 63758.23846
Subtract 1560 from 1600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
When dividing 400 by 260, we get 1 with a remainder of 140.
The next digit of our result is 1. 
Result so far: 63758.238461
Subtracting 260 from 400 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 15:
When dividing 1400 by 260, we get 5 with a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 63758.2384615
Subtracting 1300 from 1400 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 16:
If we divide 1000 by 260, we get 3 and a remainder of 220.
The next digit of our result is 3. 
Result so far: 63758.23846153
Subtracting 780 from 1000 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The quotient of the division is 63758.23846153, and the remainder is 2.2e-07.
