We divide 624201 by 45
The aim is to understand the frequency of 45 in 624201.

Going ahead to step 1:
If we divide 6 by 45, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 45

Moving on to step 2:
62 divided by 45 is 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 45 from 62 to get 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 45

Advancing to step 3:
When dividing 174 by 45, we get 3 with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 39 after subtracting 135 from 174.
Fetch the next digit (2) from the dividend, attach it to 39 and continue: 392 / 45

Let's proceed to step 4:
If we divide 392 by 45, we get 8 and a remainder of 32.
The next digit of our result is 8. 
Result so far: 138.0
Subtracting 360 from 392 leaves us with 32.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 45

Advancing to step 5:
If we divide 320 by 45, we get 7 and a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 1387.0
If we subtract 315 from 320, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 45

Let's proceed to step 6:
51 divided by 45 is 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 13871.0
Deduct 45 from 51 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
45 can be fit into 60 1 times, resulting in a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 13871.1
If we subtract 45 from 60, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
150 divided by 45 is 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 13871.13
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
45 can be fit into 150 3 times, resulting in a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 13871.133
If we take 135 away from 150, we end up 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 13871.133 and a remainder of 0.0015.
