Let's divide 803824 by 45
The aim is to understand the frequency of 45 in 803824.

Step 1:
If we divide 8 by 45, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 45

On to step 2:
80 divided by 45 is 1 with a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 45 away from 80, we end up with 35.
Fetch the next digit (3) from the dividend, attach it to 35 and continue: 353 / 45

Let's proceed to step 3:
353 divided by 45 is 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 315 from 353 and we're left with 38.
Take the next digit (8) from the dividend and append it to 38, then repeat: 388 / 45

Let's proceed to step 4:
The number 45 fits into 388 8 times, leaving a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 178.0
Deduct 360 from 388 and we're left with 28.
Append the next digit (2) from the dividend to 28 and continue with: 282 / 45

Going ahead to step 5:
45 can be fit into 282 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 1786.0
If we take 270 away from 282, we end up with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 45

On to step 6:
45 can be fit into 124 2 times, resulting in a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 17862.0
If we subtract 90 from 124, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 7:
45 can be fit into 340 7 times, resulting in a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 17862.7
Deduct 315 from 340 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 8:
If we divide 250 by 45, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 17862.75
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
The number 45 fits into 250 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 17862.755
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 17862.755, with a leftover of 0.0025.
