We look at the division of 1663474 by 529 
The aim is to understand the frequency of 529 in 1663474.

Moving on to step 1:
529 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 529

Let's proceed to step 2:
If we divide 16 by 529, we get 0 and a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 529

Going ahead to step 3:
If we divide 166 by 529, we get 0 and a remainder of 166.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 166 leaves us with 166.
Fetch the next digit (3) from the dividend, attach it to 166 and continue: 1663 / 529

Let's proceed to step 4:
529 goes into 1663 3 times with a remainder of 76.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 1587 from 1663 leaves us with 76.
Include the next digit (4) from the dividend after 76, then repeat: 764 / 529

Moving on to step 5:
If we divide 764 by 529, we get 1 and a remainder of 235.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtracting 529 from 764 leaves us with 235.
Append the next digit (7) from the dividend to 235 and continue with: 2357 / 529

Advancing to step 6:
529 goes into 2357 4 times with a remainder of 241.
Use 4 as the next digit of our solution. 
Result so far: 314.0
If we take 2116 away from 2357, we end up with 241.
Take the next digit (4) from the dividend and append it to 241, then repeat: 2414 / 529

On to step 7:
When dividing 2414 by 529, we get 4 with a remainder of 298.
Put 4 as the next digit of the answer. 
Result so far: 3144.0
The remainder is 298 after subtracting 2116 from 2414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Let's proceed to step 8:
529 goes into 2980 5 times with a remainder of 335.
The number 5 becomes the next digit in our result. 
Result so far: 3144.5
If we take 2645 away from 2980, we end up with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

On to step 9:
3350 divided by 529 is 6 with a remainder of 176.
The next digit of our result is 6. 
Result so far: 3144.56
The remainder is 176 after subtracting 3174 from 3350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 10:
When dividing 1760 by 529, we get 3 with a remainder of 173.
The number 3 becomes the next digit in our result. 
Result so far: 3144.563
Deduct 1587 from 1760 and we're left with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Let's proceed to step 11:
If we divide 1730 by 529, we get 3 and a remainder of 143.
Put 3 as the next digit of the answer. 
Result so far: 3144.5633
Subtracting 1587 from 1730 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

The final result is 3144.5633 with a remainder of 0.00143.
