We're dividing 918090 by 32 
The aim is to understand the frequency of 32 in 918090.

On to step 1:
When dividing 9 by 32, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 32

Moving on to step 2:
When dividing 91 by 32, we get 2 with a remainder of 27.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 64 from 91, we get 27.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 32

Let's proceed to step 3:
278 divided by 32 is 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Deduct 256 from 278 and we're left with 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 32

Let's proceed to step 4:
When dividing 220 by 32, we get 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 286.0
Deduct 192 from 220 and we're left with 28.
Grab the next digit (9) from the dividend, add it to 28, then carry on: 289 / 32

Going ahead to step 5:
32 goes into 289 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 2869.0
Subtract 288 from 289 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 32

Let's proceed to step 6:
The number 32 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 28690.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
If we divide 100 by 32, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 28690.3
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
When dividing 40 by 32, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 28690.31
Subtract 32 from 40 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
80 divided by 32 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 28690.312
Subtracting 64 from 80 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
The number 32 fits into 160 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 28690.3125
Deduct 160 from 160 and we're left 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.

On to step 11:
If we divide 0 by 32, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28690.3125
The remainder is 0 after subtracting 0 from 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 12:
The number 32 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28690.3125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 28690.3125 and a remainder of 0.0.
