45227280 divided by 523 
The aim is to understand the frequency of 523 in 45227280.

Going ahead to step 1:
If we divide 4 by 523, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 523

Moving on to step 2:
When dividing 45 by 523, we get 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Grab the next digit (2) from the dividend, add it to 45, then carry on: 452 / 523

Advancing to step 3:
523 can be fit into 452 0 times, resulting in a remainder of 452.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 452 and we're left with 452.
Grab the next digit (2) from the dividend, add it to 452, then carry on: 4522 / 523

Moving on to step 4:
4522 divided by 523 is 8 with a remainder of 338.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 4184 away from 4522, we end up with 338.
Include the next digit (7) from the dividend after 338, then repeat: 3387 / 523

Advancing to step 5:
3387 divided by 523 is 6 with a remainder of 249.
The next digit of our result is 6. 
Result so far: 86.0
Subtracting 3138 from 3387 leaves us with 249.
Append the next digit (2) from the dividend to 249 and continue with: 2492 / 523

Step 6:
If we divide 2492 by 523, we get 4 and a remainder of 400.
Use 4 as the next digit of our solution. 
Result so far: 864.0
Subtracting 2092 from 2492 leaves us with 400.
Bring next digit (8) of the dividend behind the 400 and repeat the process: 4008 / 523

Let's proceed to step 7:
If we divide 4008 by 523, we get 7 and a remainder of 347.
The next digit of our result is 7. 
Result so far: 8647.0
Subtract 3661 from 4008 to get 347.
Include the next digit (0) from the dividend after 347, then repeat: 3470 / 523

Advancing to step 8:
523 can be fit into 3470 6 times, resulting in a remainder of 332.
The number 6 becomes the next digit in our result. 
Result so far: 86476.0
Subtract 3138 from 3470 to get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 9:
3320 divided by 523 is 6 with a remainder of 182.
Put 6 as the next digit of the answer. 
Result so far: 86476.6
If we subtract 3138 from 3320, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Going ahead to step 10:
If we divide 1820 by 523, we get 3 and a remainder of 251.
The next digit of our result is 3. 
Result so far: 86476.63
If we take 1569 away from 1820, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Advancing to step 11:
When dividing 2510 by 523, we get 4 with a remainder of 418.
Put 4 as the next digit of the answer. 
Result so far: 86476.634
If we take 2092 away from 2510, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 12:
If we divide 4180 by 523, we get 7 and a remainder of 519.
Write down 7 as next digit of the result. 
Result so far: 86476.6347
Subtracting 3661 from 4180 leaves us with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

On to step 13:
5190 divided by 523 is 9 with a remainder of 483.
Record the quotient 9 as the next digit in the result. 
Result so far: 86476.63479
Subtracting 4707 from 5190 leaves us with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Let's proceed to step 14:
4830 divided by 523 is 9 with a remainder of 123.
Put 9 as the next digit of the answer. 
Result so far: 86476.634799
If we take 4707 away from 4830, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Our division results in 86476.634799 with a remaining 1.23e-05.
