713673 ÷ 45 
The aim is to understand the frequency of 45 in 713673.

Going ahead to step 1:
45 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 45

Step 2:
If we divide 71 by 45, we get 1 and a remainder of 26.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 45 from 71 and we're left with 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 45

Advancing to step 3:
If we divide 263 by 45, we get 5 and a remainder of 38.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 225 from 263 to get 38.
Grab the next digit (6) from the dividend, add it to 38, then carry on: 386 / 45

Moving on to step 4:
The number 45 fits into 386 8 times, leaving a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
Subtracting 360 from 386 leaves us with 26.
Bring next digit (7) of the dividend behind the 26 and repeat the process: 267 / 45

Let's proceed to step 5:
The number 45 fits into 267 5 times, leaving a remainder of 42.
Write down 5 as next digit of the result. 
Result so far: 1585.0
Deduct 225 from 267 and we're left with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 45

Moving on to step 6:
When dividing 423 by 45, we get 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 15859.0
Subtracting 405 from 423 leaves us 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.

Going ahead to step 7:
45 goes into 180 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 15859.4
If we subtract 180 from 180, 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.

Advancing to step 8:
If we divide 0 by 45, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15859.4
Subtracting 0 from 0 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 9:
When dividing 0 by 45, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15859.4
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.

Our division results in 15859.4 with a remaining 0.0.
