We divide 545014 by 90
The aim is to understand the frequency of 90 in 545014.

Advancing to step 1:
When dividing 5 by 90, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 90

On to step 2:
When dividing 54 by 90, we get 0 with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Bring next digit (5) of the dividend behind the 54 and repeat the process: 545 / 90

Let's proceed to step 3:
90 can be fit into 545 6 times, resulting in a remainder of 5.
The next digit of our result is 6. 
Result so far: 6.0
If we take 540 away from 545, we end up with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 90

Moving on to step 4:
90 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 60.0
If we subtract 0 from 50, we get 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 90

Step 5:
90 goes into 501 5 times with a remainder of 51.
Write down 5 as next digit of the result. 
Result so far: 605.0
Subtract 450 from 501 to get 51.
Take the next digit (4) from the dividend and append it to 51, then repeat: 514 / 90

On to step 6:
The number 90 fits into 514 5 times, leaving a remainder of 64.
Write down 5 as next digit of the result. 
Result so far: 6055.0
Subtracting 450 from 514 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 7:
90 goes into 640 7 times with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 6055.7
If we take 630 away from 640, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
100 divided by 90 is 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 6055.71
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
If we divide 100 by 90, we get 1 and a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 6055.711
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 6055.711 with a remainder of 0.001.
