We look at the division of 889043 by 45 
The aim is to understand the frequency of 45 in 889043.

Step 1:
If we divide 8 by 45, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 45

Going ahead to step 2:
If we divide 88 by 45, we get 1 and a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 43 after subtracting 45 from 88.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 45

On to step 3:
If we divide 439 by 45, we get 9 and a remainder of 34.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 405 from 439 leaves us with 34.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 45

Step 4:
When dividing 340 by 45, we get 7 with a remainder of 25.
The next digit of our result is 7. 
Result so far: 197.0
If we subtract 315 from 340, we get 25.
Bring next digit (4) of the dividend behind the 25 and repeat the process: 254 / 45

Let's proceed to step 5:
45 can be fit into 254 5 times, resulting in a remainder of 29.
Put 5 as the next digit of the answer. 
Result so far: 1975.0
Deduct 225 from 254 and we're left with 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 45

On to step 6:
When dividing 293 by 45, we get 6 with a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 19756.0
Subtract 270 from 293 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
45 goes into 230 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 19756.5
Subtracting 225 from 230 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
The number 45 fits into 50 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 19756.51
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
45 can be fit into 50 1 times, resulting in a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 19756.511
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 19756.511 with a remaining 0.0005.
