We're dividing 726666 by 45 
The aim is to understand the frequency of 45 in 726666.

Going ahead to step 1:
45 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 45

Going ahead to step 2:
45 goes into 72 1 times with a remainder of 27.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 45 from 72 leaves us with 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 45

Let's proceed to step 3:
45 can be fit into 276 6 times, resulting in a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 270 from 276 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 45

Step 4:
If we divide 66 by 45, we get 1 and a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 161.0
If we subtract 45 from 66, we get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 45

Let's proceed to step 5:
If we divide 216 by 45, we get 4 and a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 1614.0
Subtract 180 from 216 to get 36.
Bring next digit (6) of the dividend behind the 36 and repeat the process: 366 / 45

Let's proceed to step 6:
When dividing 366 by 45, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 16148.0
If we subtract 360 from 366, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
The number 45 fits into 60 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 16148.1
The remainder is 15 after subtracting 45 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
The number 45 fits into 150 3 times, leaving a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 16148.13
Deduct 135 from 150 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
45 goes into 150 3 times with a remainder of 15.
The next digit of our result is 3. 
Result so far: 16148.133
Deduct 135 from 150 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 16148.133 and a remainder of 0.0015.
