We look at the division of 99707224 by 415 
The aim is to understand the frequency of 415 in 99707224.

Step 1:
9 divided by 415 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 415

On to step 2:
415 can be fit into 99 0 times, resulting in a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Grab the next digit (7) from the dividend, add it to 99, then carry on: 997 / 415

Moving on to step 3:
997 divided by 415 is 2 with a remainder of 167.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 167 after subtracting 830 from 997.
Fetch the next digit (0) from the dividend, attach it to 167 and continue: 1670 / 415

Step 4:
415 can be fit into 1670 4 times, resulting in a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we take 1660 away from 1670, we end up with 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 415

Going ahead to step 5:
415 goes into 107 0 times with a remainder of 107.
Write down 0 as next digit of the result. 
Result so far: 240.0
Subtracting 0 from 107 leaves us with 107.
Append the next digit (2) from the dividend to 107 and continue with: 1072 / 415

Moving on to step 6:
If we divide 1072 by 415, we get 2 and a remainder of 242.
Write down 2 as next digit of the result. 
Result so far: 2402.0
Subtract 830 from 1072 to get 242.
Grab the next digit (2) from the dividend, add it to 242, then carry on: 2422 / 415

Going ahead to step 7:
If we divide 2422 by 415, we get 5 and a remainder of 347.
Write down 5 as next digit of the result. 
Result so far: 24025.0
The remainder is 347 after subtracting 2075 from 2422.
Take the next digit (4) from the dividend and append it to 347, then repeat: 3474 / 415

Moving on to step 8:
415 goes into 3474 8 times with a remainder of 154.
The number 8 becomes the next digit in our result. 
Result so far: 240258.0
If we subtract 3320 from 3474, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 9:
When dividing 1540 by 415, we get 3 with a remainder of 295.
The number 3 becomes the next digit in our result. 
Result so far: 240258.3
Subtract 1245 from 1540 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Step 10:
415 goes into 2950 7 times with a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 240258.37
The remainder is 45 after subtracting 2905 from 2950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 11:
450 divided by 415 is 1 with a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 240258.371
The remainder is 35 after subtracting 415 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
If we divide 350 by 415, we get 0 and a remainder of 350.
The next digit of our result is 0. 
Result so far: 240258.371
Subtract 0 from 350 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 13:
If we divide 3500 by 415, we get 8 and a remainder of 180.
The number 8 becomes the next digit in our result. 
Result so far: 240258.37108
If we subtract 3320 from 3500, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 14:
When dividing 1800 by 415, we get 4 with a remainder of 140.
Write down 4 as next digit of the result. 
Result so far: 240258.371084
Subtracting 1660 from 1800 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 15:
415 goes into 1400 3 times with a remainder of 155.
Put 3 as the next digit of the answer. 
Result so far: 240258.3710843
The remainder is 155 after subtracting 1245 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 16:
415 can be fit into 1550 3 times, resulting in a remainder of 305.
The number 3 becomes the next digit in our result. 
Result so far: 240258.37108433
Subtracting 1245 from 1550 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

After the division, we end up with 240258.37108433 and a remainder of 3.05e-07.
