Let's divide 546893 by 90
The aim is to understand the frequency of 90 in 546893.

On to step 1:
5 divided by 90 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
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

Going ahead to step 2:
The number 90 fits into 54 0 times, leaving a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Include the next digit (6) from the dividend after 54, then repeat: 546 / 90

Moving on to step 3:
546 divided by 90 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 540 from 546 and we're left with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 90

Step 4:
If we divide 68 by 90, we get 0 and a remainder of 68.
The next digit of our result is 0. 
Result so far: 60.0
Subtract 0 from 68 to get 68.
Include the next digit (9) from the dividend after 68, then repeat: 689 / 90

On to step 5:
If we divide 689 by 90, we get 7 and a remainder of 59.
Record the quotient 7 as the next digit in the result. 
Result so far: 607.0
The remainder is 59 after subtracting 630 from 689.
Append the next digit (3) from the dividend to 59 and continue with: 593 / 90

Going ahead to step 6:
The number 90 fits into 593 6 times, leaving a remainder of 53.
Record the quotient 6 as the next digit in the result. 
Result so far: 6076.0
If we subtract 540 from 593, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 7:
530 divided by 90 is 5 with a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 6076.5
If we take 450 away from 530, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 8:
800 divided by 90 is 8 with a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 6076.58
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 9:
The number 90 fits into 800 8 times, leaving a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 6076.588
Subtract 720 from 800 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

In conclusion, the division gives 6076.588 with a balance of 0.008.
