We divide 708352 by 45
The aim is to understand the frequency of 45 in 708352.

Going ahead to step 1:
If we divide 7 by 45, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 45

On to step 2:
When dividing 70 by 45, we get 1 with a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 45 from 70 leaves us with 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 45

Moving on to step 3:
45 goes into 258 5 times with a remainder of 33.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 225 from 258, we get 33.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 45

Step 4:
When dividing 333 by 45, we get 7 with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
Subtract 315 from 333 to get 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 45

Moving on to step 5:
185 divided by 45 is 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 1574.0
Deduct 180 from 185 and we're left with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 45

Going ahead to step 6:
52 divided by 45 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 15741.0
If we subtract 45 from 52, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
The number 45 fits into 70 1 times, leaving a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 15741.1
If we subtract 45 from 70, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
When dividing 250 by 45, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 15741.15
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
45 goes into 250 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 15741.155
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 15741.155 and a remainder of 0.0025.
