31276665 divided by 75 
The aim is to understand the frequency of 75 in 31276665.

On to step 1:
If we divide 3 by 75, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 75

Moving on to step 2:
75 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Bring next digit (2) of the dividend behind the 31 and repeat the process: 312 / 75

Moving on to step 3:
75 goes into 312 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 300 from 312 to get 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 75

Moving on to step 4:
The number 75 fits into 127 1 times, leaving a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 41.0
The remainder is 52 after subtracting 75 from 127.
Append the next digit (6) from the dividend to 52 and continue with: 526 / 75

Moving on to step 5:
75 goes into 526 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 417.0
Deduct 525 from 526 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 75

Step 6:
16 divided by 75 is 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 4170.0
If we take 0 away from 16, we end up with 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 75

Step 7:
If we divide 166 by 75, we get 2 and a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 41702.0
The remainder is 16 after subtracting 150 from 166.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 75

Advancing to step 8:
165 divided by 75 is 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 417022.0
If we subtract 150 from 165, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
75 goes into 150 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 417022.2
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.

Moving on to step 10:
0 divided by 75 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 417022.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
The number 75 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 417022.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 417022.2 with a remaining 0.0.
