Let's divide 917912 by 75
The aim is to understand the frequency of 75 in 917912.

Let's proceed to step 1:
If we divide 9 by 75, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 75

Moving on to step 2:
75 can be fit into 91 1 times, resulting in a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 16 after subtracting 75 from 91.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 75

Step 3:
75 goes into 167 2 times with a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 150 from 167 and we're left with 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 75

Moving on to step 4:
75 can be fit into 179 2 times, resulting in a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
Subtract 150 from 179 to get 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 75

Step 5:
291 divided by 75 is 3 with a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 1223.0
Deduct 225 from 291 and we're left with 66.
Bring next digit (2) of the dividend behind the 66 and repeat the process: 662 / 75

Moving on to step 6:
When dividing 662 by 75, we get 8 with a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 12238.0
Subtract 600 from 662 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 7:
75 can be fit into 620 8 times, resulting in a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 12238.8
If we take 600 away from 620, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
75 goes into 200 2 times with a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 12238.82
Subtracting 150 from 200 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 12238.826
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
If we divide 500 by 75, we get 6 and a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 12238.8266
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 12238.8266 with a remaining 0.0005.
