We look at the division of 22315639 by 513 
The aim is to understand the frequency of 513 in 22315639.

Let's proceed to step 1:
If we divide 2 by 513, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 513

On to step 2:
When dividing 22 by 513, we get 0 with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 513

On to step 3:
If we divide 223 by 513, we get 0 and a remainder of 223.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 223, we get 223.
Grab the next digit (1) from the dividend, add it to 223, then carry on: 2231 / 513

Step 4:
If we divide 2231 by 513, we get 4 and a remainder of 179.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 2052 away from 2231, we end up with 179.
Include the next digit (5) from the dividend after 179, then repeat: 1795 / 513

Advancing to step 5:
1795 divided by 513 is 3 with a remainder of 256.
The next digit of our result is 3. 
Result so far: 43.0
Subtracting 1539 from 1795 leaves us with 256.
Take the next digit (6) from the dividend and append it to 256, then repeat: 2566 / 513

Going ahead to step 6:
2566 divided by 513 is 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 435.0
The remainder is 1 after subtracting 2565 from 2566.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 513

Advancing to step 7:
When dividing 13 by 513, we get 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 4350.0
Subtract 0 from 13 to get 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 513

Moving on to step 8:
513 can be fit into 139 0 times, resulting in a remainder of 139.
Use 0 as the next digit of our solution. 
Result so far: 43500.0
The remainder is 139 after subtracting 0 from 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Step 9:
1390 divided by 513 is 2 with a remainder of 364.
Write down 2 as next digit of the result. 
Result so far: 43500.2
Subtracting 1026 from 1390 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Let's proceed to step 10:
If we divide 3640 by 513, we get 7 and a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 43500.27
The remainder is 49 after subtracting 3591 from 3640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 11:
The number 513 fits into 490 0 times, leaving a remainder of 490.
Put 0 as the next digit of the answer. 
Result so far: 43500.27
The remainder is 490 after subtracting 0 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 12:
When dividing 4900 by 513, we get 9 with a remainder of 283.
The number 9 becomes the next digit in our result. 
Result so far: 43500.2709
If we subtract 4617 from 4900, we get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Advancing to step 13:
513 can be fit into 2830 5 times, resulting in a remainder of 265.
Put 5 as the next digit of the answer. 
Result so far: 43500.27095
Subtract 2565 from 2830 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 14:
The number 513 fits into 2650 5 times, leaving a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 43500.270955
Subtracting 2565 from 2650 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final outcome is 43500.270955, with a leftover of 8.5e-06.
