We look at the division of 73106329 by 529 
The aim is to understand the frequency of 529 in 73106329.

Step 1:
If we divide 7 by 529, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 529

On to step 2:
When dividing 73 by 529, we get 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Grab the next digit (1) from the dividend, add it to 73, then carry on: 731 / 529

Advancing to step 3:
529 can be fit into 731 1 times, resulting in a remainder of 202.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 529 from 731 leaves us with 202.
Bring next digit (0) of the dividend behind the 202 and repeat the process: 2020 / 529

On to step 4:
The number 529 fits into 2020 3 times, leaving a remainder of 433.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1587 from 2020 leaves us with 433.
Include the next digit (6) from the dividend after 433, then repeat: 4336 / 529

On to step 5:
The number 529 fits into 4336 8 times, leaving a remainder of 104.
The number 8 becomes the next digit in our result. 
Result so far: 138.0
Subtract 4232 from 4336 to get 104.
Take the next digit (3) from the dividend and append it to 104, then repeat: 1043 / 529

Step 6:
1043 divided by 529 is 1 with a remainder of 514.
The next digit of our result is 1. 
Result so far: 1381.0
If we take 529 away from 1043, we end up with 514.
Include the next digit (2) from the dividend after 514, then repeat: 5142 / 529

On to step 7:
If we divide 5142 by 529, we get 9 and a remainder of 381.
The number 9 becomes the next digit in our result. 
Result so far: 13819.0
The remainder is 381 after subtracting 4761 from 5142.
Append the next digit (9) from the dividend to 381 and continue with: 3819 / 529

Going ahead to step 8:
529 can be fit into 3819 7 times, resulting in a remainder of 116.
Record the quotient 7 as the next digit in the result. 
Result so far: 138197.0
Subtracting 3703 from 3819 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 9:
529 goes into 1160 2 times with a remainder of 102.
Record the quotient 2 as the next digit in the result. 
Result so far: 138197.2
If we subtract 1058 from 1160, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 10:
529 goes into 1020 1 times with a remainder of 491.
Write down 1 as next digit of the result. 
Result so far: 138197.21
The remainder is 491 after subtracting 529 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Step 11:
The number 529 fits into 4910 9 times, leaving a remainder of 149.
Use 9 as the next digit of our solution. 
Result so far: 138197.219
If we subtract 4761 from 4910, we get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

On to step 12:
1490 divided by 529 is 2 with a remainder of 432.
The next digit of our result is 2. 
Result so far: 138197.2192
If we take 1058 away from 1490, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 13:
529 can be fit into 4320 8 times, resulting in a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 138197.21928
If we subtract 4232 from 4320, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 14:
If we divide 880 by 529, we get 1 and a remainder of 351.
Use 1 as the next digit of our solution. 
Result so far: 138197.219281
If we subtract 529 from 880, we get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Going ahead to step 15:
529 goes into 3510 6 times with a remainder of 336.
Write down 6 as next digit of the result. 
Result so far: 138197.2192816
Subtracting 3174 from 3510 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 16:
529 goes into 3360 6 times with a remainder of 186.
Use 6 as the next digit of our solution. 
Result so far: 138197.21928166
If we subtract 3174 from 3360, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

The final outcome is 138197.21928166, with a leftover of 1.86e-07.
