We're dividing 672948 by 45 
The aim is to understand the frequency of 45 in 672948.

Moving on to step 1:
The number 45 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 45

Advancing to step 2:
If we divide 67 by 45, we get 1 and a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 45 from 67, we get 22.
Grab the next digit (2) from the dividend, add it to 22, then carry on: 222 / 45

On to step 3:
The number 45 fits into 222 4 times, leaving a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 180 from 222 and we're left with 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 45

Moving on to step 4:
45 goes into 429 9 times with a remainder of 24.
The next digit of our result is 9. 
Result so far: 149.0
If we take 405 away from 429, we end up with 24.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 45

Let's proceed to step 5:
244 divided by 45 is 5 with a remainder of 19.
The next digit of our result is 5. 
Result so far: 1495.0
Subtract 225 from 244 to get 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 45

Step 6:
198 divided by 45 is 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 14954.0
If we take 180 away from 198, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
If we divide 180 by 45, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 14954.4
If we take 180 away from 180, we end up 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.

Step 8:
When dividing 0 by 45, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14954.4
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.

Let's proceed to step 9:
The number 45 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14954.4
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.

The final outcome is 14954.4, with a leftover of 0.0.
