458127 ÷ 45 
The aim is to understand the frequency of 45 in 458127.

Advancing to step 1:
The number 45 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 45

Step 2:
45 divided by 45 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 45 from 45 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 45

Advancing to step 3:
45 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 45

Moving on to step 4:
If we divide 81 by 45, we get 1 and a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Deduct 45 from 81 and we're left with 36.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 45

Going ahead to step 5:
The number 45 fits into 362 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 1018.0
If we take 360 away from 362, we end up with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 45

Let's proceed to step 6:
27 divided by 45 is 0 with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 10180.0
The remainder is 27 after subtracting 0 from 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
The number 45 fits into 270 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 10180.6
Subtracting 270 from 270 leaves us 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 8:
0 divided by 45 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10180.6
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
0 divided by 45 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10180.6
Subtract 0 from 0 to get 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 10180.6 and a remainder of 0.0.
