Let's divide 434183 by 90
The aim is to understand the frequency of 90 in 434183.

Let's proceed to step 1:
If we divide 4 by 90, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 90

Advancing to step 2:
90 goes into 43 0 times with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Bring next digit (4) of the dividend behind the 43 and repeat the process: 434 / 90

Let's proceed to step 3:
90 can be fit into 434 4 times, resulting in a remainder of 74.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 74 after subtracting 360 from 434.
Fetch the next digit (1) from the dividend, attach it to 74 and continue: 741 / 90

Step 4:
90 can be fit into 741 8 times, resulting in a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtract 720 from 741 to get 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 90

Going ahead to step 5:
The number 90 fits into 218 2 times, leaving a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 482.0
Subtract 180 from 218 to get 38.
Grab the next digit (3) from the dividend, add it to 38, then carry on: 383 / 90

Advancing to step 6:
When dividing 383 by 90, we get 4 with a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 4824.0
The remainder is 23 after subtracting 360 from 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
If we divide 230 by 90, we get 2 and a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 4824.2
Deduct 180 from 230 and we're left 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.

Advancing to step 8:
When dividing 500 by 90, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 4824.25
Deduct 450 from 500 and we're left 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.

Advancing to step 9:
When dividing 500 by 90, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 4824.255
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.

After the division, we end up with 4824.255 and a remainder of 0.005.
