Let's divide 445049 by 90
The aim is to understand the frequency of 90 in 445049.

Advancing to step 1:
90 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 90

Let's proceed to step 2:
The number 90 fits into 44 0 times, leaving a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 90

On to step 3:
When dividing 445 by 90, we get 4 with a remainder of 85.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 360 from 445, we get 85.
Append the next digit (0) from the dividend to 85 and continue with: 850 / 90

Let's proceed to step 4:
When dividing 850 by 90, we get 9 with a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 49.0
The remainder is 40 after subtracting 810 from 850.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 90

Going ahead to step 5:
If we divide 404 by 90, we get 4 and a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 494.0
The remainder is 44 after subtracting 360 from 404.
Grab the next digit (9) from the dividend, add it to 44, then carry on: 449 / 90

Moving on to step 6:
The number 90 fits into 449 4 times, leaving a remainder of 89.
Write down 4 as next digit of the result. 
Result so far: 4944.0
The remainder is 89 after subtracting 360 from 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 7:
The number 90 fits into 890 9 times, leaving a remainder of 80.
Write down 9 as next digit of the result. 
Result so far: 4944.9
Subtracting 810 from 890 leaves us 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.

On to step 8:
If we divide 800 by 90, we get 8 and a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 4944.98
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 9:
800 divided by 90 is 8 with a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 4944.988
Deduct 720 from 800 and we're left 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.

Our division results in 4944.988 with a remaining 0.008.
