We look at the division of 873315 by 75 
The aim is to understand the frequency of 75 in 873315.

Step 1:
If we divide 8 by 75, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 75

Step 2:
If we divide 87 by 75, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 75 from 87 and we're left with 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 75

Going ahead to step 3:
If we divide 123 by 75, we get 1 and a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 48 after subtracting 75 from 123.
Grab the next digit (3) from the dividend, add it to 48, then carry on: 483 / 75

Let's proceed to step 4:
75 goes into 483 6 times with a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 116.0
If we take 450 away from 483, we end up with 33.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 75

Step 5:
If we divide 331 by 75, we get 4 and a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 1164.0
Deduct 300 from 331 and we're left with 31.
Append the next digit (5) from the dividend to 31 and continue with: 315 / 75

Step 6:
When dividing 315 by 75, we get 4 with a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 11644.0
Deduct 300 from 315 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
The number 75 fits into 150 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 11644.2
Deduct 150 from 150 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 75 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 11644.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
If we divide 0 by 75, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11644.2
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 11644.2, with a leftover of 0.0.
