Let's divide 463919 by 90
The aim is to understand the frequency of 90 in 463919.

Moving on to step 1:
4 divided by 90 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 90

Advancing to step 2:
90 goes into 46 0 times with a remainder of 46.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 46 to get 46.
Take the next digit (3) from the dividend and append it to 46, then repeat: 463 / 90

Let's proceed to step 3:
463 divided by 90 is 5 with a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 450 from 463 and we're left with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 90

Moving on to step 4:
90 goes into 139 1 times with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 51.0
The remainder is 49 after subtracting 90 from 139.
Include the next digit (1) from the dividend after 49, then repeat: 491 / 90

Let's proceed to step 5:
90 can be fit into 491 5 times, resulting in a remainder of 41.
The next digit of our result is 5. 
Result so far: 515.0
The remainder is 41 after subtracting 450 from 491.
Fetch the next digit (9) from the dividend, attach it to 41 and continue: 419 / 90

On to step 6:
419 divided by 90 is 4 with a remainder of 59.
Use 4 as the next digit of our solution. 
Result so far: 5154.0
The remainder is 59 after subtracting 360 from 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 7:
590 divided by 90 is 6 with a remainder of 50.
The next digit of our result is 6. 
Result so far: 5154.6
Subtracting 540 from 590 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
90 goes into 500 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 5154.65
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 5154.655
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 5154.655 with a remaining 0.005.
