477418 ÷ 90 
The aim is to understand the frequency of 90 in 477418.

On to step 1:
90 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 90

Step 2:
The number 90 fits into 47 0 times, leaving a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 47, we get 47.
Include the next digit (7) from the dividend after 47, then repeat: 477 / 90

Going ahead to step 3:
477 divided by 90 is 5 with a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 27 after subtracting 450 from 477.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 90

Let's proceed to step 4:
90 goes into 274 3 times with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 53.0
Subtract 270 from 274 to get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 90

Let's proceed to step 5:
When dividing 41 by 90, we get 0 with a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 530.0
If we subtract 0 from 41, we get 41.
Bring next digit (8) of the dividend behind the 41 and repeat the process: 418 / 90

On to step 6:
The number 90 fits into 418 4 times, leaving a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 5304.0
Subtracting 360 from 418 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 7:
90 can be fit into 580 6 times, resulting in a remainder of 40.
The next digit of our result is 6. 
Result so far: 5304.6
Subtracting 540 from 580 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
400 divided by 90 is 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 5304.64
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
When dividing 400 by 90, we get 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 5304.644
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 5304.644, and the remainder is 0.004.
