Let's divide 76455444 by 515
The aim is to understand the frequency of 515 in 76455444.

Moving on to step 1:
515 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 515

On to step 2:
If we divide 76 by 515, we get 0 and a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Include the next digit (4) from the dividend after 76, then repeat: 764 / 515

Moving on to step 3:
If we divide 764 by 515, we get 1 and a remainder of 249.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 515 from 764 leaves us with 249.
Append the next digit (5) from the dividend to 249 and continue with: 2495 / 515

Let's proceed to step 4:
2495 divided by 515 is 4 with a remainder of 435.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 435 after subtracting 2060 from 2495.
Take the next digit (5) from the dividend and append it to 435, then repeat: 4355 / 515

Let's proceed to step 5:
515 goes into 4355 8 times with a remainder of 235.
Use 8 as the next digit of our solution. 
Result so far: 148.0
Subtract 4120 from 4355 to get 235.
Bring next digit (4) of the dividend behind the 235 and repeat the process: 2354 / 515

Going ahead to step 6:
2354 divided by 515 is 4 with a remainder of 294.
Use 4 as the next digit of our solution. 
Result so far: 1484.0
The remainder is 294 after subtracting 2060 from 2354.
Grab the next digit (4) from the dividend, add it to 294, then carry on: 2944 / 515

On to step 7:
The number 515 fits into 2944 5 times, leaving a remainder of 369.
The number 5 becomes the next digit in our result. 
Result so far: 14845.0
The remainder is 369 after subtracting 2575 from 2944.
Grab the next digit (4) from the dividend, add it to 369, then carry on: 3694 / 515

Advancing to step 8:
When dividing 3694 by 515, we get 7 with a remainder of 89.
Write down 7 as next digit of the result. 
Result so far: 148457.0
Subtract 3605 from 3694 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 9:
515 goes into 890 1 times with a remainder of 375.
Record the quotient 1 as the next digit in the result. 
Result so far: 148457.1
If we subtract 515 from 890, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

On to step 10:
If we divide 3750 by 515, we get 7 and a remainder of 145.
The number 7 becomes the next digit in our result. 
Result so far: 148457.17
Deduct 3605 from 3750 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 11:
If we divide 1450 by 515, we get 2 and a remainder of 420.
Record the quotient 2 as the next digit in the result. 
Result so far: 148457.172
Deduct 1030 from 1450 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 12:
4200 divided by 515 is 8 with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 148457.1728
Subtract 4120 from 4200 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
When dividing 800 by 515, we get 1 with a remainder of 285.
Use 1 as the next digit of our solution. 
Result so far: 148457.17281
The remainder is 285 after subtracting 515 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 14:
515 can be fit into 2850 5 times, resulting in a remainder of 275.
The next digit of our result is 5. 
Result so far: 148457.172815
Subtracting 2575 from 2850 leaves us with 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 15:
The number 515 fits into 2750 5 times, leaving a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 148457.1728155
If we subtract 2575 from 2750, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

The final outcome is 148457.1728155, with a leftover of 1.75e-06.
