We look at the division of 22193593 by 445 
The aim is to understand the frequency of 445 in 22193593.

On to step 1:
445 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 445

Moving on to step 2:
22 divided by 445 is 0 with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 445

Let's proceed to step 3:
When dividing 221 by 445, we get 0 with a remainder of 221.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 221 and we're left with 221.
Bring next digit (9) of the dividend behind the 221 and repeat the process: 2219 / 445

Step 4:
445 goes into 2219 4 times with a remainder of 439.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 1780 from 2219 to get 439.
Bring next digit (3) of the dividend behind the 439 and repeat the process: 4393 / 445

On to step 5:
If we divide 4393 by 445, we get 9 and a remainder of 388.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we take 4005 away from 4393, we end up with 388.
Grab the next digit (5) from the dividend, add it to 388, then carry on: 3885 / 445

Let's proceed to step 6:
The number 445 fits into 3885 8 times, leaving a remainder of 325.
The number 8 becomes the next digit in our result. 
Result so far: 498.0
The remainder is 325 after subtracting 3560 from 3885.
Append the next digit (9) from the dividend to 325 and continue with: 3259 / 445

Going ahead to step 7:
When dividing 3259 by 445, we get 7 with a remainder of 144.
Put 7 as the next digit of the answer. 
Result so far: 4987.0
If we take 3115 away from 3259, we end up with 144.
Append the next digit (3) from the dividend to 144 and continue with: 1443 / 445

Advancing to step 8:
445 can be fit into 1443 3 times, resulting in a remainder of 108.
Write down 3 as next digit of the result. 
Result so far: 49873.0
Deduct 1335 from 1443 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 9:
When dividing 1080 by 445, we get 2 with a remainder of 190.
Put 2 as the next digit of the answer. 
Result so far: 49873.2
If we take 890 away from 1080, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 10:
If we divide 1900 by 445, we get 4 and a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 49873.24
Subtracting 1780 from 1900 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
445 can be fit into 1200 2 times, resulting in a remainder of 310.
Record the quotient 2 as the next digit in the result. 
Result so far: 49873.242
Subtract 890 from 1200 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 12:
When dividing 3100 by 445, we get 6 with a remainder of 430.
The next digit of our result is 6. 
Result so far: 49873.2426
If we take 2670 away from 3100, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 13:
When dividing 4300 by 445, we get 9 with a remainder of 295.
Use 9 as the next digit of our solution. 
Result so far: 49873.24269
Subtract 4005 from 4300 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Moving on to step 14:
If we divide 2950 by 445, we get 6 and a remainder of 280.
Use 6 as the next digit of our solution. 
Result so far: 49873.242696
If we subtract 2670 from 2950, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 15:
If we divide 2800 by 445, we get 6 and a remainder of 130.
Write down 6 as next digit of the result. 
Result so far: 49873.2426966
If we subtract 2670 from 2800, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Our division results in 49873.2426966 with a remaining 1.3e-06.
