345853 divided by 75 
The aim is to understand the frequency of 75 in 345853.

Let's proceed to step 1:
75 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 75

Going ahead to step 2:
When dividing 34 by 75, we get 0 with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 75

Step 3:
If we divide 345 by 75, we get 4 and a remainder of 45.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 300 from 345 to get 45.
Grab the next digit (8) from the dividend, add it to 45, then carry on: 458 / 75

Going ahead to step 4:
The number 75 fits into 458 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
Subtracting 450 from 458 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 75

Moving on to step 5:
The number 75 fits into 85 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 461.0
Subtracting 75 from 85 leaves us with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 75

On to step 6:
If we divide 103 by 75, we get 1 and a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 4611.0
The remainder is 28 after subtracting 75 from 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
The number 75 fits into 280 3 times, leaving a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 4611.3
Deduct 225 from 280 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 8:
75 goes into 550 7 times with a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 4611.37
Subtract 525 from 550 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
When dividing 250 by 75, we get 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 4611.373
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
If we divide 250 by 75, we get 3 and a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 4611.3733
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 4611.3733, with a leftover of 0.00025.
