We divide 546420 by 75
The aim is to understand the frequency of 75 in 546420.

Step 1:
5 divided by 75 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 75

Advancing to step 2:
If we divide 54 by 75, we get 0 and a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Append the next digit (6) from the dividend to 54 and continue with: 546 / 75

Advancing to step 3:
75 goes into 546 7 times with a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 525 from 546 to get 21.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 75

Let's proceed to step 4:
75 can be fit into 214 2 times, resulting in a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 72.0
If we subtract 150 from 214, we get 64.
Include the next digit (2) from the dividend after 64, then repeat: 642 / 75

Moving on to step 5:
75 goes into 642 8 times with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 728.0
Subtracting 600 from 642 leaves us with 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 75

Let's proceed to step 6:
The number 75 fits into 420 5 times, leaving a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 7285.0
The remainder is 45 after subtracting 375 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
When dividing 450 by 75, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 7285.6
Deduct 450 from 450 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.

Let's proceed to step 8:
75 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7285.6
If we take 0 away from 0, we end up 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.

Let's proceed to step 9:
0 divided by 75 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7285.6
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.

The quotient of the division is 7285.6, and the remainder is 0.0.
