We're dividing 22145491 by 515 
The aim is to understand the frequency of 515 in 22145491.

Going ahead to step 1:
If we divide 2 by 515, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 515

Let's proceed to step 2:
When dividing 22 by 515, we get 0 with a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 515

Step 3:
The number 515 fits into 221 0 times, leaving a remainder of 221.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 221 leaves us with 221.
Bring next digit (4) of the dividend behind the 221 and repeat the process: 2214 / 515

Let's proceed to step 4:
The number 515 fits into 2214 4 times, leaving a remainder of 154.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 2060 from 2214 and we're left with 154.
Include the next digit (5) from the dividend after 154, then repeat: 1545 / 515

Moving on to step 5:
515 goes into 1545 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
If we subtract 1545 from 1545, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 515

Let's proceed to step 6:
515 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 430.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 515

Let's proceed to step 7:
515 goes into 49 0 times with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 4300.0
The remainder is 49 after subtracting 0 from 49.
Bring next digit (1) of the dividend behind the 49 and repeat the process: 491 / 515

Going ahead to step 8:
When dividing 491 by 515, we get 0 with a remainder of 491.
Put 0 as the next digit of the answer. 
Result so far: 43000.0
Subtracting 0 from 491 leaves us with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Advancing to step 9:
The number 515 fits into 4910 9 times, leaving a remainder of 275.
Write down 9 as next digit of the result. 
Result so far: 43000.9
If we subtract 4635 from 4910, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 10:
2750 divided by 515 is 5 with a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 43000.95
If we take 2575 away from 2750, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 11:
515 goes into 1750 3 times with a remainder of 205.
Record the quotient 3 as the next digit in the result. 
Result so far: 43000.953
Deduct 1545 from 1750 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 12:
2050 divided by 515 is 3 with a remainder of 505.
Write down 3 as next digit of the result. 
Result so far: 43000.9533
If we take 1545 away from 2050, we end up with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

The final outcome is 43000.9533, with a leftover of 0.00505.
