298586 ÷ 75 
The aim is to understand the frequency of 75 in 298586.

Going ahead to step 1:
75 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 75

Let's proceed to step 2:
75 can be fit into 29 0 times, resulting in a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 75

Moving on to step 3:
When dividing 298 by 75, we get 3 with a remainder of 73.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 225 away from 298, we end up with 73.
Include the next digit (5) from the dividend after 73, then repeat: 735 / 75

Let's proceed to step 4:
If we divide 735 by 75, we get 9 and a remainder of 60.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we subtract 675 from 735, we get 60.
Grab the next digit (8) from the dividend, add it to 60, then carry on: 608 / 75

Step 5:
608 divided by 75 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 398.0
Subtract 600 from 608 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 75

Step 6:
75 can be fit into 86 1 times, resulting in a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 3981.0
Deduct 75 from 86 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
75 can be fit into 110 1 times, resulting in a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 3981.1
If we subtract 75 from 110, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 8:
75 can be fit into 350 4 times, resulting in a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 3981.14
Subtracting 300 from 350 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.

Advancing to step 9:
The number 75 fits into 500 6 times, leaving a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 3981.146
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
The number 75 fits into 500 6 times, leaving a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 3981.1466
The remainder is 50 after subtracting 450 from 500.
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 outcome is 3981.1466, with a leftover of 0.0005.
