We're dividing 15282224 by 813 
The aim is to understand the frequency of 813 in 15282224.

Let's proceed to step 1:
When dividing 1 by 813, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 813

Going ahead to step 2:
When dividing 15 by 813, we get 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 813

Moving on to step 3:
813 goes into 152 0 times with a remainder of 152.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 152 after subtracting 0 from 152.
Grab the next digit (8) from the dividend, add it to 152, then carry on: 1528 / 813

Moving on to step 4:
If we divide 1528 by 813, we get 1 and a remainder of 715.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 813 from 1528 leaves us with 715.
Include the next digit (2) from the dividend after 715, then repeat: 7152 / 813

Going ahead to step 5:
813 goes into 7152 8 times with a remainder of 648.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Deduct 6504 from 7152 and we're left with 648.
Append the next digit (2) from the dividend to 648 and continue with: 6482 / 813

Going ahead to step 6:
The number 813 fits into 6482 7 times, leaving a remainder of 791.
Record the quotient 7 as the next digit in the result. 
Result so far: 187.0
If we take 5691 away from 6482, we end up with 791.
Take the next digit (2) from the dividend and append it to 791, then repeat: 7912 / 813

Moving on to step 7:
813 can be fit into 7912 9 times, resulting in a remainder of 595.
Record the quotient 9 as the next digit in the result. 
Result so far: 1879.0
Deduct 7317 from 7912 and we're left with 595.
Fetch the next digit (4) from the dividend, attach it to 595 and continue: 5954 / 813

Going ahead to step 8:
813 can be fit into 5954 7 times, resulting in a remainder of 263.
Record the quotient 7 as the next digit in the result. 
Result so far: 18797.0
Deduct 5691 from 5954 and we're left with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Going ahead to step 9:
2630 divided by 813 is 3 with a remainder of 191.
The number 3 becomes the next digit in our result. 
Result so far: 18797.3
Subtracting 2439 from 2630 leaves us with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

On to step 10:
If we divide 1910 by 813, we get 2 and a remainder of 284.
Use 2 as the next digit of our solution. 
Result so far: 18797.32
Subtracting 1626 from 1910 leaves us with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 11:
When dividing 2840 by 813, we get 3 with a remainder of 401.
The next digit of our result is 3. 
Result so far: 18797.323
If we subtract 2439 from 2840, we get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

On to step 12:
When dividing 4010 by 813, we get 4 with a remainder of 758.
Use 4 as the next digit of our solution. 
Result so far: 18797.3234
Subtract 3252 from 4010 to get 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

Moving on to step 13:
813 can be fit into 7580 9 times, resulting in a remainder of 263.
Use 9 as the next digit of our solution. 
Result so far: 18797.32349
If we take 7317 away from 7580, we end up with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Step 14:
The number 813 fits into 2630 3 times, leaving a remainder of 191.
The next digit of our result is 3. 
Result so far: 18797.323493
If we subtract 2439 from 2630, we get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Step 15:
The number 813 fits into 1910 2 times, leaving a remainder of 284.
The next digit of our result is 2. 
Result so far: 18797.3234932
Deduct 1626 from 1910 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Advancing to step 16:
813 can be fit into 2840 3 times, resulting in a remainder of 401.
Write down 3 as next digit of the result. 
Result so far: 18797.32349323
If we subtract 2439 from 2840, we get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

After the division, we end up with 18797.32349323 and a remainder of 4.01e-07.
