471844 ÷ 45 
The aim is to understand the frequency of 45 in 471844.

On to step 1:
45 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 45

Going ahead to step 2:
When dividing 47 by 45, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 45 from 47 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 45

Going ahead to step 3:
21 divided by 45 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 45

Advancing to step 4:
If we divide 218 by 45, we get 4 and a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
Subtract 180 from 218 to get 38.
Grab the next digit (4) from the dividend, add it to 38, then carry on: 384 / 45

On to step 5:
45 goes into 384 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 1048.0
If we subtract 360 from 384, we get 24.
Grab the next digit (4) from the dividend, add it to 24, then carry on: 244 / 45

Advancing to step 6:
45 goes into 244 5 times with a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 10485.0
Subtract 225 from 244 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
If we divide 190 by 45, we get 4 and a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 10485.4
If we subtract 180 from 190, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 45, we get 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 10485.42
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
If we divide 100 by 45, we get 2 and a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 10485.422
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 10485.422 with a remaining 0.001.
