52101135 divided by 260 
The aim is to understand the frequency of 260 in 52101135.

Step 1:
5 divided by 260 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 260

On to step 2:
The number 260 fits into 52 0 times, leaving a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 260

Going ahead to step 3:
The number 260 fits into 521 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 520 from 521, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 260

Let's proceed to step 4:
260 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
The remainder is 10 after subtracting 0 from 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 260

Going ahead to step 5:
The number 260 fits into 101 0 times, leaving a remainder of 101.
Use 0 as the next digit of our solution. 
Result so far: 200.0
Deduct 0 from 101 and we're left with 101.
Bring next digit (1) of the dividend behind the 101 and repeat the process: 1011 / 260

Advancing to step 6:
260 goes into 1011 3 times with a remainder of 231.
Put 3 as the next digit of the answer. 
Result so far: 2003.0
Subtract 780 from 1011 to get 231.
Take the next digit (3) from the dividend and append it to 231, then repeat: 2313 / 260

Let's proceed to step 7:
260 can be fit into 2313 8 times, resulting in a remainder of 233.
Use 8 as the next digit of our solution. 
Result so far: 20038.0
If we subtract 2080 from 2313, we get 233.
Fetch the next digit (5) from the dividend, attach it to 233 and continue: 2335 / 260

Going ahead to step 8:
260 can be fit into 2335 8 times, resulting in a remainder of 255.
Write down 8 as next digit of the result. 
Result so far: 200388.0
Subtract 2080 from 2335 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Advancing to step 9:
2550 divided by 260 is 9 with a remainder of 210.
Write down 9 as next digit of the result. 
Result so far: 200388.9
If we take 2340 away from 2550, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 10:
When dividing 2100 by 260, we get 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 200388.98
Subtracting 2080 from 2100 leaves us 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.

On to step 11:
260 goes into 200 0 times with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 200388.98
Subtracting 0 from 200 leaves us 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.

Step 12:
The number 260 fits into 2000 7 times, leaving a remainder of 180.
The next digit of our result is 7. 
Result so far: 200388.9807
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.

Moving on to step 13:
260 goes into 1800 6 times with a remainder of 240.
The number 6 becomes the next digit in our result. 
Result so far: 200388.98076
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.

Going ahead to step 14:
When dividing 2400 by 260, we get 9 with a remainder of 60.
The next digit of our result is 9. 
Result so far: 200388.980769
Deduct 2340 from 2400 and we're left 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.

Step 15:
260 can be fit into 600 2 times, resulting in a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 200388.9807692
Subtracting 520 from 600 leaves us 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.

Step 16:
260 goes into 800 3 times with a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 200388.98076923
Subtracting 780 from 800 leaves us 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.

The quotient of the division is 200388.98076923, and the remainder is 2e-08.
