We divide 105403 by 45
The aim is to understand the frequency of 45 in 105403.

Advancing to step 1:
45 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 45

Moving on to step 2:
45 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 45

On to step 3:
105 divided by 45 is 2 with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 90 from 105 leaves us with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 45

Let's proceed to step 4:
154 divided by 45 is 3 with a remainder of 19.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 19 after subtracting 135 from 154.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 45

Advancing to step 5:
45 can be fit into 190 4 times, resulting in a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 234.0
If we subtract 180 from 190, we get 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 45

Step 6:
45 can be fit into 103 2 times, resulting in a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 2342.0
The remainder is 13 after subtracting 90 from 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
If we divide 130 by 45, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 2342.2
Subtract 90 from 130 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
If we divide 400 by 45, we get 8 and a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 2342.28
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
When dividing 400 by 45, we get 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 2342.288
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 2342.288, with a leftover of 0.004.
