We divide 81277197 by 529
The aim is to understand the frequency of 529 in 81277197.

Advancing to step 1:
8 divided by 529 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 529

On to step 2:
When dividing 81 by 529, we get 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Grab the next digit (2) from the dividend, add it to 81, then carry on: 812 / 529

Moving on to step 3:
When dividing 812 by 529, we get 1 with a remainder of 283.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 283 after subtracting 529 from 812.
Bring next digit (7) of the dividend behind the 283 and repeat the process: 2837 / 529

Advancing to step 4:
If we divide 2837 by 529, we get 5 and a remainder of 192.
The next digit of our result is 5. 
Result so far: 15.0
If we take 2645 away from 2837, we end up with 192.
Fetch the next digit (7) from the dividend, attach it to 192 and continue: 1927 / 529

Moving on to step 5:
The number 529 fits into 1927 3 times, leaving a remainder of 340.
Put 3 as the next digit of the answer. 
Result so far: 153.0
Deduct 1587 from 1927 and we're left with 340.
Include the next digit (1) from the dividend after 340, then repeat: 3401 / 529

Advancing to step 6:
If we divide 3401 by 529, we get 6 and a remainder of 227.
The next digit of our result is 6. 
Result so far: 1536.0
If we subtract 3174 from 3401, we get 227.
Bring next digit (9) of the dividend behind the 227 and repeat the process: 2279 / 529

On to step 7:
The number 529 fits into 2279 4 times, leaving a remainder of 163.
Write down 4 as next digit of the result. 
Result so far: 15364.0
If we subtract 2116 from 2279, we get 163.
Grab the next digit (7) from the dividend, add it to 163, then carry on: 1637 / 529

On to step 8:
529 can be fit into 1637 3 times, resulting in a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 153643.0
If we take 1587 away from 1637, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
The number 529 fits into 500 0 times, leaving a remainder of 500.
The next digit of our result is 0. 
Result so far: 153643.0
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 10:
529 can be fit into 5000 9 times, resulting in a remainder of 239.
The next digit of our result is 9. 
Result so far: 153643.09
Deduct 4761 from 5000 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Let's proceed to step 11:
The number 529 fits into 2390 4 times, leaving a remainder of 274.
Use 4 as the next digit of our solution. 
Result so far: 153643.094
If we take 2116 away from 2390, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

On to step 12:
The number 529 fits into 2740 5 times, leaving a remainder of 95.
Put 5 as the next digit of the answer. 
Result so far: 153643.0945
If we subtract 2645 from 2740, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 13:
If we divide 950 by 529, we get 1 and a remainder of 421.
Use 1 as the next digit of our solution. 
Result so far: 153643.09451
Subtract 529 from 950 to get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Step 14:
If we divide 4210 by 529, we get 7 and a remainder of 507.
Write down 7 as next digit of the result. 
Result so far: 153643.094517
The remainder is 507 after subtracting 3703 from 4210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Moving on to step 15:
If we divide 5070 by 529, we get 9 and a remainder of 309.
Put 9 as the next digit of the answer. 
Result so far: 153643.0945179
The remainder is 309 after subtracting 4761 from 5070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Going ahead to step 16:
When dividing 3090 by 529, we get 5 with a remainder of 445.
The next digit of our result is 5. 
Result so far: 153643.09451795
Deduct 2645 from 3090 and we're left with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Our division results in 153643.09451795 with a remaining 4.45e-07.
