407727 divided by 90 
The aim is to understand the frequency of 90 in 407727.

Moving on to step 1:
90 goes into 4 0 times with 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.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 90

Going ahead to step 2:
When dividing 40 by 90, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Fetch the next digit (7) from the dividend, attach it to 40 and continue: 407 / 90

Let's proceed to step 3:
90 can be fit into 407 4 times, resulting in a remainder of 47.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 360 from 407, we get 47.
Include the next digit (7) from the dividend after 47, then repeat: 477 / 90

Going ahead to step 4:
477 divided by 90 is 5 with a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
If we subtract 450 from 477, we get 27.
Include the next digit (2) from the dividend after 27, then repeat: 272 / 90

Advancing to step 5:
If we divide 272 by 90, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 453.0
If we subtract 270 from 272, we get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 90

On to step 6:
90 goes into 27 0 times with a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 4530.0
Subtracting 0 from 27 leaves us 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 7:
270 divided by 90 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 4530.3
If we take 270 away from 270, we end up 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.

Step 8:
0 divided by 90 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4530.3
Subtract 0 from 0 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.

Advancing to step 9:
90 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4530.3
Subtract 0 from 0 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.

In conclusion, the division gives 4530.3 with a balance of 0.0.
