We divide 450094 by 90
The aim is to understand the frequency of 90 in 450094.

Let's proceed to step 1:
The number 90 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 90

Let's proceed to step 2:
If we divide 45 by 90, we get 0 and a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 90

Let's proceed to step 3:
90 goes into 450 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 450 from 450, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 90

Step 4:
0 divided by 90 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
If we take 0 away from 0, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 90

Moving on to step 5:
When dividing 9 by 90, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 500.0
Subtract 0 from 9 to get 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 90

On to step 6:
The number 90 fits into 94 1 times, leaving a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 5001.0
Subtracting 90 from 94 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
The number 90 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 5001.0
If we take 0 away from 40, we end up 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.

Step 8:
If we divide 400 by 90, we get 4 and a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 5001.04
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.

On to step 9:
90 can be fit into 400 4 times, resulting in a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 5001.044
The remainder is 40 after subtracting 360 from 400.
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 5001.044, and the remainder is 0.004.
