We divide 90454257 by 45
The aim is to understand the frequency of 45 in 90454257.

Going ahead to step 1:
45 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 45

Let's proceed to step 2:
90 divided by 45 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 0 after subtracting 90 from 90.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 45

Step 3:
4 divided by 45 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 4, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 45

Going ahead to step 4:
If we divide 45 by 45, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 201.0
If we subtract 45 from 45, we get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 45

On to step 5:
When dividing 4 by 45, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 2010.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 45

On to step 6:
When dividing 42 by 45, we get 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 20100.0
The remainder is 42 after subtracting 0 from 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 45

Going ahead to step 7:
45 goes into 425 9 times with a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 201009.0
If we take 405 away from 425, we end up with 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 45

Going ahead to step 8:
45 can be fit into 207 4 times, resulting in a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 2010094.0
Deduct 180 from 207 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 9:
45 can be fit into 270 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 2010094.6
Subtract 270 from 270 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
If we divide 0 by 45, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2010094.6
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
45 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2010094.6
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 2010094.6 with a balance of 0.0.
