We're dividing 19397883 by 445 
The aim is to understand the frequency of 445 in 19397883.

Moving on to step 1:
445 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 445

Step 2:
If we divide 19 by 445, we get 0 and a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 445

Step 3:
If we divide 193 by 445, we get 0 and a remainder of 193.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 193 leaves us with 193.
Grab the next digit (9) from the dividend, add it to 193, then carry on: 1939 / 445

Let's proceed to step 4:
445 can be fit into 1939 4 times, resulting in a remainder of 159.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 159 after subtracting 1780 from 1939.
Include the next digit (7) from the dividend after 159, then repeat: 1597 / 445

Step 5:
When dividing 1597 by 445, we get 3 with a remainder of 262.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Deduct 1335 from 1597 and we're left with 262.
Fetch the next digit (8) from the dividend, attach it to 262 and continue: 2628 / 445

Going ahead to step 6:
If we divide 2628 by 445, we get 5 and a remainder of 403.
The next digit of our result is 5. 
Result so far: 435.0
Subtracting 2225 from 2628 leaves us with 403.
Take the next digit (8) from the dividend and append it to 403, then repeat: 4038 / 445

Step 7:
445 goes into 4038 9 times with a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 4359.0
If we take 4005 away from 4038, we end up with 33.
Include the next digit (3) from the dividend after 33, then repeat: 333 / 445

Advancing to step 8:
445 goes into 333 0 times with a remainder of 333.
Use 0 as the next digit of our solution. 
Result so far: 43590.0
Subtract 0 from 333 to get 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Let's proceed to step 9:
If we divide 3330 by 445, we get 7 and a remainder of 215.
The number 7 becomes the next digit in our result. 
Result so far: 43590.7
The remainder is 215 after subtracting 3115 from 3330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 10:
2150 divided by 445 is 4 with a remainder of 370.
The next digit of our result is 4. 
Result so far: 43590.74
Subtract 1780 from 2150 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 11:
If we divide 3700 by 445, we get 8 and a remainder of 140.
Record the quotient 8 as the next digit in the result. 
Result so far: 43590.748
Subtracting 3560 from 3700 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 12:
1400 divided by 445 is 3 with a remainder of 65.
The number 3 becomes the next digit in our result. 
Result so far: 43590.7483
If we take 1335 away from 1400, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 13:
650 divided by 445 is 1 with a remainder of 205.
The number 1 becomes the next digit in our result. 
Result so far: 43590.74831
If we take 445 away from 650, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 14:
445 can be fit into 2050 4 times, resulting in a remainder of 270.
Use 4 as the next digit of our solution. 
Result so far: 43590.748314
If we take 1780 away from 2050, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 15:
The number 445 fits into 2700 6 times, leaving a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 43590.7483146
Subtract 2670 from 2700 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 16:
The number 445 fits into 300 0 times, leaving a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 43590.7483146
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 43590.7483146, with a leftover of 3e-07.
