We're dividing 812462 by 45 
The aim is to understand the frequency of 45 in 812462.

Going ahead to step 1:
8 divided by 45 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 45

Let's proceed to step 2:
45 can be fit into 81 1 times, resulting in a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 36 after subtracting 45 from 81.
Bring next digit (2) of the dividend behind the 36 and repeat the process: 362 / 45

Step 3:
362 divided by 45 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 2 after subtracting 360 from 362.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 45

Let's proceed to step 4:
24 divided by 45 is 0 with a remainder of 24.
The next digit of our result is 0. 
Result so far: 180.0
If we take 0 away from 24, we end up with 24.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 45

On to step 5:
The number 45 fits into 246 5 times, leaving a remainder of 21.
The next digit of our result is 5. 
Result so far: 1805.0
Subtracting 225 from 246 leaves us with 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 45

Step 6:
45 can be fit into 212 4 times, resulting in a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 18054.0
Subtract 180 from 212 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
When dividing 320 by 45, we get 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 18054.7
Deduct 315 from 320 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
45 goes into 50 1 times with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 18054.71
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
The number 45 fits into 50 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 18054.711
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 18054.711 and a remainder of 0.0005.
