We're dividing 26577014 by 523 
The aim is to understand the frequency of 523 in 26577014.

Step 1:
When dividing 2 by 523, we get 0 with 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.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 523

Going ahead to step 2:
If we divide 26 by 523, we get 0 and a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 523

Let's proceed to step 3:
The number 523 fits into 265 0 times, leaving a remainder of 265.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 265 and we're left with 265.
Bring next digit (7) of the dividend behind the 265 and repeat the process: 2657 / 523

Step 4:
2657 divided by 523 is 5 with a remainder of 42.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 2615 from 2657, we get 42.
Grab the next digit (7) from the dividend, add it to 42, then carry on: 427 / 523

Advancing to step 5:
When dividing 427 by 523, we get 0 with a remainder of 427.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtracting 0 from 427 leaves us with 427.
Include the next digit (0) from the dividend after 427, then repeat: 4270 / 523

Moving on to step 6:
523 can be fit into 4270 8 times, resulting in a remainder of 86.
The next digit of our result is 8. 
Result so far: 508.0
If we take 4184 away from 4270, we end up with 86.
Bring next digit (1) of the dividend behind the 86 and repeat the process: 861 / 523

Moving on to step 7:
If we divide 861 by 523, we get 1 and a remainder of 338.
Write down 1 as next digit of the result. 
Result so far: 5081.0
If we subtract 523 from 861, we get 338.
Grab the next digit (4) from the dividend, add it to 338, then carry on: 3384 / 523

Moving on to step 8:
523 can be fit into 3384 6 times, resulting in a remainder of 246.
The next digit of our result is 6. 
Result so far: 50816.0
If we subtract 3138 from 3384, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 9:
2460 divided by 523 is 4 with a remainder of 368.
The next digit of our result is 4. 
Result so far: 50816.4
The remainder is 368 after subtracting 2092 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 10:
523 can be fit into 3680 7 times, resulting in a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 50816.47
Subtract 3661 from 3680 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 11:
If we divide 190 by 523, we get 0 and a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 50816.47
Deduct 0 from 190 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 12:
523 can be fit into 1900 3 times, resulting in a remainder of 331.
The number 3 becomes the next digit in our result. 
Result so far: 50816.4703
Subtract 1569 from 1900 to get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Going ahead to step 13:
When dividing 3310 by 523, we get 6 with a remainder of 172.
Use 6 as the next digit of our solution. 
Result so far: 50816.47036
Deduct 3138 from 3310 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 14:
523 can be fit into 1720 3 times, resulting in a remainder of 151.
The number 3 becomes the next digit in our result. 
Result so far: 50816.470363
If we subtract 1569 from 1720, we get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 15:
1510 divided by 523 is 2 with a remainder of 464.
Put 2 as the next digit of the answer. 
Result so far: 50816.4703632
Subtract 1046 from 1510 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

On to step 16:
523 can be fit into 4640 8 times, resulting in a remainder of 456.
Record the quotient 8 as the next digit in the result. 
Result so far: 50816.47036328
The remainder is 456 after subtracting 4184 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

After the division, we end up with 50816.47036328 and a remainder of 4.56e-07.
