80644888 divided by 529 
The aim is to understand the frequency of 529 in 80644888.

Moving on to step 1:
If we divide 8 by 529, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 529

Let's proceed to step 2:
529 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Bring next digit (6) of the dividend behind the 80 and repeat the process: 806 / 529

Advancing to step 3:
The number 529 fits into 806 1 times, leaving a remainder of 277.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 277 after subtracting 529 from 806.
Include the next digit (4) from the dividend after 277, then repeat: 2774 / 529

On to step 4:
2774 divided by 529 is 5 with a remainder of 129.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 2645 from 2774, we get 129.
Take the next digit (4) from the dividend and append it to 129, then repeat: 1294 / 529

Let's proceed to step 5:
529 goes into 1294 2 times with a remainder of 236.
The next digit of our result is 2. 
Result so far: 152.0
Deduct 1058 from 1294 and we're left with 236.
Take the next digit (8) from the dividend and append it to 236, then repeat: 2368 / 529

Let's proceed to step 6:
529 can be fit into 2368 4 times, resulting in a remainder of 252.
The next digit of our result is 4. 
Result so far: 1524.0
Subtract 2116 from 2368 to get 252.
Take the next digit (8) from the dividend and append it to 252, then repeat: 2528 / 529

Going ahead to step 7:
529 can be fit into 2528 4 times, resulting in a remainder of 412.
Write down 4 as next digit of the result. 
Result so far: 15244.0
Subtract 2116 from 2528 to get 412.
Bring next digit (8) of the dividend behind the 412 and repeat the process: 4128 / 529

Advancing to step 8:
The number 529 fits into 4128 7 times, leaving a remainder of 425.
Record the quotient 7 as the next digit in the result. 
Result so far: 152447.0
If we subtract 3703 from 4128, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Let's proceed to step 9:
If we divide 4250 by 529, we get 8 and a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 152447.8
Deduct 4232 from 4250 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
529 can be fit into 180 0 times, resulting in a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 152447.8
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 11:
When dividing 1800 by 529, we get 3 with a remainder of 213.
Record the quotient 3 as the next digit in the result. 
Result so far: 152447.803
If we subtract 1587 from 1800, we get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Advancing to step 12:
529 can be fit into 2130 4 times, resulting in a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 152447.8034
If we subtract 2116 from 2130, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
529 goes into 140 0 times with a remainder of 140.
The next digit of our result is 0. 
Result so far: 152447.8034
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 14:
529 can be fit into 1400 2 times, resulting in a remainder of 342.
Record the quotient 2 as the next digit in the result. 
Result so far: 152447.803402
If we subtract 1058 from 1400, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 15:
529 goes into 3420 6 times with a remainder of 246.
Put 6 as the next digit of the answer. 
Result so far: 152447.8034026
The remainder is 246 after subtracting 3174 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 16:
When dividing 2460 by 529, we get 4 with a remainder of 344.
Use 4 as the next digit of our solution. 
Result so far: 152447.80340264
If we subtract 2116 from 2460, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

After the division, we end up with 152447.80340264 and a remainder of 3.44e-07.
