26106212 divided by 523 
The aim is to understand the frequency of 523 in 26106212.

On to step 1:
The number 523 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 523

On to step 2:
When dividing 26 by 523, we get 0 with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 523

On to step 3:
When dividing 261 by 523, we get 0 with a remainder of 261.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 261, we end up with 261.
Append the next digit (0) from the dividend to 261 and continue with: 2610 / 523

Moving on to step 4:
523 can be fit into 2610 4 times, resulting in a remainder of 518.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 2092 from 2610 and we're left with 518.
Append the next digit (6) from the dividend to 518 and continue with: 5186 / 523

Let's proceed to step 5:
If we divide 5186 by 523, we get 9 and a remainder of 479.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Subtract 4707 from 5186 to get 479.
Include the next digit (2) from the dividend after 479, then repeat: 4792 / 523

On to step 6:
4792 divided by 523 is 9 with a remainder of 85.
Put 9 as the next digit of the answer. 
Result so far: 499.0
If we subtract 4707 from 4792, we get 85.
Append the next digit (1) from the dividend to 85 and continue with: 851 / 523

Step 7:
If we divide 851 by 523, we get 1 and a remainder of 328.
The number 1 becomes the next digit in our result. 
Result so far: 4991.0
If we take 523 away from 851, we end up with 328.
Bring next digit (2) of the dividend behind the 328 and repeat the process: 3282 / 523

Let's proceed to step 8:
The number 523 fits into 3282 6 times, leaving a remainder of 144.
Put 6 as the next digit of the answer. 
Result so far: 49916.0
If we subtract 3138 from 3282, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 9:
If we divide 1440 by 523, we get 2 and a remainder of 394.
The next digit of our result is 2. 
Result so far: 49916.2
Deduct 1046 from 1440 and we're left with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Advancing to step 10:
3940 divided by 523 is 7 with a remainder of 279.
Write down 7 as next digit of the result. 
Result so far: 49916.27
If we subtract 3661 from 3940, we get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Going ahead to step 11:
2790 divided by 523 is 5 with a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 49916.275
Subtracting 2615 from 2790 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 12:
523 goes into 1750 3 times with a remainder of 181.
Put 3 as the next digit of the answer. 
Result so far: 49916.2753
The remainder is 181 after subtracting 1569 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Moving on to step 13:
The number 523 fits into 1810 3 times, leaving a remainder of 241.
Write down 3 as next digit of the result. 
Result so far: 49916.27533
Subtract 1569 from 1810 to get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

The final outcome is 49916.27533, with a leftover of 0.000241.
