749063 ÷ 45 
The aim is to understand the frequency of 45 in 749063.

Advancing to step 1:
45 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 45

Moving on to step 2:
45 goes into 74 1 times with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 45 from 74, we get 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 45

On to step 3:
If we divide 299 by 45, we get 6 and a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 270 from 299 leaves us with 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 45

On to step 4:
The number 45 fits into 290 6 times, leaving a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 166.0
Subtracting 270 from 290 leaves us with 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 45

Step 5:
45 goes into 206 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 1664.0
Deduct 180 from 206 and we're left with 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 45

On to step 6:
45 goes into 263 5 times with a remainder of 38.
Put 5 as the next digit of the answer. 
Result so far: 16645.0
Subtracting 225 from 263 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
If we divide 380 by 45, we get 8 and a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 16645.8
The remainder is 20 after subtracting 360 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
45 goes into 200 4 times with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 16645.84
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
45 goes into 200 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 16645.844
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 16645.844 and a remainder of 0.002.
