We look at the division of 279049 by 45 
The aim is to understand the frequency of 45 in 279049.

Step 1:
45 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 45

Advancing to step 2:
The number 45 fits into 27 0 times, leaving a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 45

Step 3:
45 goes into 279 6 times with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 270 from 279 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 45

Moving on to step 4:
45 goes into 90 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 62.0
If we take 90 away from 90, we end up with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 45

Let's proceed to step 5:
The number 45 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 620.0
If we subtract 0 from 4, we get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 45

Let's proceed to step 6:
If we divide 49 by 45, we get 1 and a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 6201.0
Subtract 45 from 49 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
45 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 6201.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
45 can be fit into 400 8 times, resulting in a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 6201.08
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
45 goes into 400 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 6201.088
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 6201.088, with a leftover of 0.004.
