268886 ÷ 45 
The aim is to understand the frequency of 45 in 268886.

Step 1:
45 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 45

Going ahead to step 2:
45 goes into 26 0 times with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 45

Moving on to step 3:
If we divide 268 by 45, we get 5 and a remainder of 43.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 225 from 268 to get 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 45

Going ahead to step 4:
When dividing 438 by 45, we get 9 with a remainder of 33.
The next digit of our result is 9. 
Result so far: 59.0
If we take 405 away from 438, we end up with 33.
Bring next digit (8) of the dividend behind the 33 and repeat the process: 338 / 45

Moving on to step 5:
If we divide 338 by 45, we get 7 and a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 597.0
If we take 315 away from 338, we end up with 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 45

Moving on to step 6:
The number 45 fits into 236 5 times, leaving a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 5975.0
If we take 225 away from 236, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
45 goes into 110 2 times with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 5975.2
Subtract 90 from 110 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
45 can be fit into 200 4 times, resulting in a remainder of 20.
The next digit of our result is 4. 
Result so far: 5975.24
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.

Moving on to step 9:
45 can be fit into 200 4 times, resulting in a remainder of 20.
The next digit of our result is 4. 
Result so far: 5975.244
If we take 180 away from 200, we end up 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 5975.244 and a remainder of 0.002.
