Let's divide 675644 by 75
The aim is to understand the frequency of 75 in 675644.

Step 1:
6 divided by 75 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 75

Let's proceed to step 2:
75 can be fit into 67 0 times, resulting in a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Fetch the next digit (5) from the dividend, attach it to 67 and continue: 675 / 75

Let's proceed to step 3:
75 can be fit into 675 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 675 away from 675, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 75

Moving on to step 4:
If we divide 6 by 75, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 90.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 75

Let's proceed to step 5:
64 divided by 75 is 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 900.0
If we subtract 0 from 64, we get 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 75

On to step 6:
When dividing 644 by 75, we get 8 with a remainder of 44.
The next digit of our result is 8. 
Result so far: 9008.0
If we subtract 600 from 644, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 7:
The number 75 fits into 440 5 times, leaving a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 9008.5
The remainder is 65 after subtracting 375 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 8:
75 goes into 650 8 times with a remainder of 50.
The number 8 becomes the next digit in our result. 
Result so far: 9008.58
Deduct 600 from 650 and we're left 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.

Going ahead to step 9:
500 divided by 75 is 6 with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 9008.586
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.

Moving on to step 10:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 9008.5866
If we take 450 away from 500, we end up 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.

The final result is 9008.5866 with a remainder of 0.0005.
