Let's divide 71726289 by 530
The aim is to understand the frequency of 530 in 71726289.

Going ahead to step 1:
7 divided by 530 is 0 with 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.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 530

Going ahead to step 2:
If we divide 71 by 530, we get 0 and a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Include the next digit (7) from the dividend after 71, then repeat: 717 / 530

Going ahead to step 3:
When dividing 717 by 530, we get 1 with a remainder of 187.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 530 from 717 leaves us with 187.
Grab the next digit (2) from the dividend, add it to 187, then carry on: 1872 / 530

Step 4:
If we divide 1872 by 530, we get 3 and a remainder of 282.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 282 after subtracting 1590 from 1872.
Include the next digit (6) from the dividend after 282, then repeat: 2826 / 530

Advancing to step 5:
530 can be fit into 2826 5 times, resulting in a remainder of 176.
The number 5 becomes the next digit in our result. 
Result so far: 135.0
Subtract 2650 from 2826 to get 176.
Bring next digit (2) of the dividend behind the 176 and repeat the process: 1762 / 530

Advancing to step 6:
If we divide 1762 by 530, we get 3 and a remainder of 172.
The next digit of our result is 3. 
Result so far: 1353.0
The remainder is 172 after subtracting 1590 from 1762.
Take the next digit (8) from the dividend and append it to 172, then repeat: 1728 / 530

Going ahead to step 7:
When dividing 1728 by 530, we get 3 with a remainder of 138.
Put 3 as the next digit of the answer. 
Result so far: 13533.0
Deduct 1590 from 1728 and we're left with 138.
Grab the next digit (9) from the dividend, add it to 138, then carry on: 1389 / 530

Advancing to step 8:
The number 530 fits into 1389 2 times, leaving a remainder of 329.
Put 2 as the next digit of the answer. 
Result so far: 135332.0
The remainder is 329 after subtracting 1060 from 1389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Advancing to step 9:
The number 530 fits into 3290 6 times, leaving a remainder of 110.
The number 6 becomes the next digit in our result. 
Result so far: 135332.6
If we subtract 3180 from 3290, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 10:
1100 divided by 530 is 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 135332.62
If we subtract 1060 from 1100, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
When dividing 400 by 530, we get 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 135332.62
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 12:
When dividing 4000 by 530, we get 7 with a remainder of 290.
Put 7 as the next digit of the answer. 
Result so far: 135332.6207
Deduct 3710 from 4000 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 13:
When dividing 2900 by 530, we get 5 with a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 135332.62075
Deduct 2650 from 2900 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 14:
The number 530 fits into 2500 4 times, leaving a remainder of 380.
The next digit of our result is 4. 
Result so far: 135332.620754
Subtracting 2120 from 2500 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 15:
When dividing 3800 by 530, we get 7 with a remainder of 90.
Put 7 as the next digit of the answer. 
Result so far: 135332.6207547
The remainder is 90 after subtracting 3710 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 16:
900 divided by 530 is 1 with a remainder of 370.
Use 1 as the next digit of our solution. 
Result so far: 135332.62075471
Deduct 530 from 900 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

After the division, we end up with 135332.62075471 and a remainder of 3.7e-07.
