We're dividing 37417949 by 515 
The aim is to understand the frequency of 515 in 37417949.

Going ahead to step 1:
The number 515 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 515

Let's proceed to step 2:
515 goes into 37 0 times with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 515

Step 3:
The number 515 fits into 374 0 times, leaving a remainder of 374.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 374 after subtracting 0 from 374.
Grab the next digit (1) from the dividend, add it to 374, then carry on: 3741 / 515

Going ahead to step 4:
515 can be fit into 3741 7 times, resulting in a remainder of 136.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 136 after subtracting 3605 from 3741.
Grab the next digit (7) from the dividend, add it to 136, then carry on: 1367 / 515

Step 5:
If we divide 1367 by 515, we get 2 and a remainder of 337.
The next digit of our result is 2. 
Result so far: 72.0
If we subtract 1030 from 1367, we get 337.
Include the next digit (9) from the dividend after 337, then repeat: 3379 / 515

Moving on to step 6:
The number 515 fits into 3379 6 times, leaving a remainder of 289.
Record the quotient 6 as the next digit in the result. 
Result so far: 726.0
Subtracting 3090 from 3379 leaves us with 289.
Include the next digit (4) from the dividend after 289, then repeat: 2894 / 515

Going ahead to step 7:
The number 515 fits into 2894 5 times, leaving a remainder of 319.
Write down 5 as next digit of the result. 
Result so far: 7265.0
If we subtract 2575 from 2894, we get 319.
Take the next digit (9) from the dividend and append it to 319, then repeat: 3199 / 515

On to step 8:
If we divide 3199 by 515, we get 6 and a remainder of 109.
Write down 6 as next digit of the result. 
Result so far: 72656.0
Deduct 3090 from 3199 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 9:
515 goes into 1090 2 times with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 72656.2
The remainder is 60 after subtracting 1030 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
The number 515 fits into 600 1 times, leaving a remainder of 85.
Write down 1 as next digit of the result. 
Result so far: 72656.21
Subtracting 515 from 600 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.

Step 11:
850 divided by 515 is 1 with a remainder of 335.
The next digit of our result is 1. 
Result so far: 72656.211
Subtract 515 from 850 to get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

The final result is 72656.211 with a remainder of 0.0335.
