We look at the division of 3904576 by 529 
The aim is to understand the frequency of 529 in 3904576.

Step 1:
529 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 529

Advancing to step 2:
The number 529 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 529

Moving on to step 3:
The number 529 fits into 390 0 times, leaving a remainder of 390.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 390 to get 390.
Take the next digit (4) from the dividend and append it to 390, then repeat: 3904 / 529

Moving on to step 4:
529 goes into 3904 7 times with a remainder of 201.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 3703 from 3904 and we're left with 201.
Append the next digit (5) from the dividend to 201 and continue with: 2015 / 529

Advancing to step 5:
The number 529 fits into 2015 3 times, leaving a remainder of 428.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Deduct 1587 from 2015 and we're left with 428.
Take the next digit (7) from the dividend and append it to 428, then repeat: 4287 / 529

Moving on to step 6:
529 goes into 4287 8 times with a remainder of 55.
Record the quotient 8 as the next digit in the result. 
Result so far: 738.0
If we subtract 4232 from 4287, we get 55.
Include the next digit (6) from the dividend after 55, then repeat: 556 / 529

Let's proceed to step 7:
The number 529 fits into 556 1 times, leaving a remainder of 27.
The next digit of our result is 1. 
Result so far: 7381.0
If we subtract 529 from 556, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 8:
529 goes into 270 0 times with a remainder of 270.
Record the quotient 0 as the next digit in the result. 
Result so far: 7381.0
The remainder is 270 after subtracting 0 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 9:
If we divide 2700 by 529, we get 5 and a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 7381.05
Deduct 2645 from 2700 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 10:
550 divided by 529 is 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 7381.051
If we take 529 away from 550, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 11:
529 goes into 210 0 times with a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 7381.051
Subtracting 0 from 210 leaves us 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.

On to step 12:
The number 529 fits into 2100 3 times, leaving a remainder of 513.
The next digit of our result is 3. 
Result so far: 7381.05103
If we take 1587 away from 2100, we end up with 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Moving on to step 13:
529 can be fit into 5130 9 times, resulting in a remainder of 369.
The number 9 becomes the next digit in our result. 
Result so far: 7381.051039
Subtract 4761 from 5130 to get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Going ahead to step 14:
529 goes into 3690 6 times with a remainder of 516.
Put 6 as the next digit of the answer. 
Result so far: 7381.0510396
The remainder is 516 after subtracting 3174 from 3690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Moving on to step 15:
529 goes into 5160 9 times with a remainder of 399.
The next digit of our result is 9. 
Result so far: 7381.05103969
Subtracting 4761 from 5160 leaves us with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

The final outcome is 7381.05103969, with a leftover of 3.99e-07.
