We're dividing 2245717 by 445 
The aim is to understand the frequency of 445 in 2245717.

On to step 1:
The number 445 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 445

Going ahead to step 2:
When dividing 22 by 445, we get 0 with a remainder of 22.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Fetch the next digit (4) from the dividend, attach it to 22 and continue: 224 / 445

Advancing to step 3:
When dividing 224 by 445, we get 0 with a remainder of 224.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 224 after subtracting 0 from 224.
Append the next digit (5) from the dividend to 224 and continue with: 2245 / 445

Let's proceed to step 4:
445 goes into 2245 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 20 after subtracting 2225 from 2245.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 445

Step 5:
445 goes into 207 0 times with a remainder of 207.
The next digit of our result is 0. 
Result so far: 50.0
If we take 0 away from 207, we end up with 207.
Grab the next digit (1) from the dividend, add it to 207, then carry on: 2071 / 445

Let's proceed to step 6:
If we divide 2071 by 445, we get 4 and a remainder of 291.
The next digit of our result is 4. 
Result so far: 504.0
If we subtract 1780 from 2071, we get 291.
Include the next digit (7) from the dividend after 291, then repeat: 2917 / 445

Advancing to step 7:
The number 445 fits into 2917 6 times, leaving a remainder of 247.
Record the quotient 6 as the next digit in the result. 
Result so far: 5046.0
If we subtract 2670 from 2917, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Let's proceed to step 8:
445 can be fit into 2470 5 times, resulting in a remainder of 245.
The next digit of our result is 5. 
Result so far: 5046.5
If we take 2225 away from 2470, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Advancing to step 9:
If we divide 2450 by 445, we get 5 and a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 5046.55
If we subtract 2225 from 2450, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

After the division, we end up with 5046.55 and a remainder of 0.225.
