336663 ÷ 75 
The aim is to understand the frequency of 75 in 336663.

On to step 1:
3 divided by 75 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 75

Advancing to step 2:
The number 75 fits into 33 0 times, leaving a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Fetch the next digit (6) from the dividend, attach it to 33 and continue: 336 / 75

Let's proceed to step 3:
75 goes into 336 4 times with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 300 from 336 and we're left with 36.
Take the next digit (6) from the dividend and append it to 36, then repeat: 366 / 75

Going ahead to step 4:
The number 75 fits into 366 4 times, leaving a remainder of 66.
The next digit of our result is 4. 
Result so far: 44.0
If we take 300 away from 366, we end up with 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 75

Moving on to step 5:
The number 75 fits into 666 8 times, leaving a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 448.0
Deduct 600 from 666 and we're left with 66.
Bring next digit (3) of the dividend behind the 66 and repeat the process: 663 / 75

Let's proceed to step 6:
The number 75 fits into 663 8 times, leaving a remainder of 63.
The number 8 becomes the next digit in our result. 
Result so far: 4488.0
The remainder is 63 after subtracting 600 from 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 7:
When dividing 630 by 75, we get 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 4488.8
The remainder is 30 after subtracting 600 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
75 goes into 300 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4488.84
If we subtract 300 from 300, 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.

Let's proceed to step 9:
0 divided by 75 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4488.84
Deduct 0 from 0 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:
When dividing 0 by 75, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4488.84
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.

The final outcome is 4488.84, with a leftover of 0.0.
