We look at the division of 71864234 by 915 
The aim is to understand the frequency of 915 in 71864234.

Moving on to step 1:
If we divide 7 by 915, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 915

Let's proceed to step 2:
If we divide 71 by 915, we get 0 and a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Take the next digit (8) from the dividend and append it to 71, then repeat: 718 / 915

Step 3:
915 can be fit into 718 0 times, resulting in a remainder of 718.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 718 to get 718.
Bring next digit (6) of the dividend behind the 718 and repeat the process: 7186 / 915

Moving on to step 4:
7186 divided by 915 is 7 with a remainder of 781.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 6405 away from 7186, we end up with 781.
Bring next digit (4) of the dividend behind the 781 and repeat the process: 7814 / 915

Moving on to step 5:
If we divide 7814 by 915, we get 8 and a remainder of 494.
Use 8 as the next digit of our solution. 
Result so far: 78.0
The remainder is 494 after subtracting 7320 from 7814.
Fetch the next digit (2) from the dividend, attach it to 494 and continue: 4942 / 915

Let's proceed to step 6:
If we divide 4942 by 915, we get 5 and a remainder of 367.
Use 5 as the next digit of our solution. 
Result so far: 785.0
Subtract 4575 from 4942 to get 367.
Bring next digit (3) of the dividend behind the 367 and repeat the process: 3673 / 915

Moving on to step 7:
915 goes into 3673 4 times with a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 7854.0
Subtracting 3660 from 3673 leaves us with 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 915

Let's proceed to step 8:
915 goes into 134 0 times with a remainder of 134.
Use 0 as the next digit of our solution. 
Result so far: 78540.0
Subtract 0 from 134 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 9:
The number 915 fits into 1340 1 times, leaving a remainder of 425.
Use 1 as the next digit of our solution. 
Result so far: 78540.1
If we subtract 915 from 1340, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

On to step 10:
The number 915 fits into 4250 4 times, leaving a remainder of 590.
Put 4 as the next digit of the answer. 
Result so far: 78540.14
Deduct 3660 from 4250 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 11:
When dividing 5900 by 915, we get 6 with a remainder of 410.
The next digit of our result is 6. 
Result so far: 78540.146
If we subtract 5490 from 5900, we get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 12:
When dividing 4100 by 915, we get 4 with a remainder of 440.
The next digit of our result is 4. 
Result so far: 78540.1464
Subtracting 3660 from 4100 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 13:
The number 915 fits into 4400 4 times, leaving a remainder of 740.
Put 4 as the next digit of the answer. 
Result so far: 78540.14644
If we take 3660 away from 4400, we end up with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

The final result is 78540.14644 with a remainder of 0.00074.
