36417 divided by 90 
The aim is to understand the frequency of 90 in 36417.

Going ahead to step 1:
When dividing 3 by 90, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 90

Going ahead to step 2:
90 goes into 36 0 times with a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 90

Let's proceed to step 3:
If we divide 364 by 90, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 360 from 364 and we're left with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 90

On to step 4:
When dividing 41 by 90, we get 0 with a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 40.0
The remainder is 41 after subtracting 0 from 41.
Grab the next digit (7) from the dividend, add it to 41, then carry on: 417 / 90

Step 5:
90 goes into 417 4 times with a remainder of 57.
Record the quotient 4 as the next digit in the result. 
Result so far: 404.0
Deduct 360 from 417 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 6:
The number 90 fits into 570 6 times, leaving a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 404.6
If we take 540 away from 570, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
300 divided by 90 is 3 with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 404.63
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
90 can be fit into 300 3 times, resulting in a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 404.633
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 404.633, and the remainder is 0.003.
