We look at the division of 19409009 by 950 
The aim is to understand the frequency of 950 in 19409009.

Step 1:
If we divide 1 by 950, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 950

Let's proceed to step 2:
The number 950 fits into 19 0 times, leaving a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 950

Moving on to step 3:
950 goes into 194 0 times with a remainder of 194.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 194 after subtracting 0 from 194.
Include the next digit (0) from the dividend after 194, then repeat: 1940 / 950

Going ahead to step 4:
If we divide 1940 by 950, we get 2 and a remainder of 40.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1900 from 1940, we get 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 950

Moving on to step 5:
When dividing 409 by 950, we get 0 with a remainder of 409.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtracting 0 from 409 leaves us with 409.
Append the next digit (0) from the dividend to 409 and continue with: 4090 / 950

Moving on to step 6:
The number 950 fits into 4090 4 times, leaving a remainder of 290.
Write down 4 as next digit of the result. 
Result so far: 204.0
If we take 3800 away from 4090, we end up with 290.
Fetch the next digit (0) from the dividend, attach it to 290 and continue: 2900 / 950

Step 7:
If we divide 2900 by 950, we get 3 and a remainder of 50.
The next digit of our result is 3. 
Result so far: 2043.0
If we subtract 2850 from 2900, we get 50.
Append the next digit (9) from the dividend to 50 and continue with: 509 / 950

Moving on to step 8:
When dividing 509 by 950, we get 0 with a remainder of 509.
Put 0 as the next digit of the answer. 
Result so far: 20430.0
The remainder is 509 after subtracting 0 from 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Step 9:
When dividing 5090 by 950, we get 5 with a remainder of 340.
Write down 5 as next digit of the result. 
Result so far: 20430.5
If we subtract 4750 from 5090, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 10:
950 can be fit into 3400 3 times, resulting in a remainder of 550.
The number 3 becomes the next digit in our result. 
Result so far: 20430.53
Subtract 2850 from 3400 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 11:
The number 950 fits into 5500 5 times, leaving a remainder of 750.
Write down 5 as next digit of the result. 
Result so far: 20430.535
Subtract 4750 from 5500 to get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Advancing to step 12:
7500 divided by 950 is 7 with a remainder of 850.
Write down 7 as next digit of the result. 
Result so far: 20430.5357
If we subtract 6650 from 7500, we get 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Going ahead to step 13:
8500 divided by 950 is 8 with a remainder of 900.
Use 8 as the next digit of our solution. 
Result so far: 20430.53578
The remainder is 900 after subtracting 7600 from 8500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Advancing to step 14:
The number 950 fits into 9000 9 times, leaving a remainder of 450.
The number 9 becomes the next digit in our result. 
Result so far: 20430.535789
Subtracting 8550 from 9000 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 15:
If we divide 4500 by 950, we get 4 and a remainder of 700.
Record the quotient 4 as the next digit in the result. 
Result so far: 20430.5357894
Subtracting 3800 from 4500 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 16:
When dividing 7000 by 950, we get 7 with a remainder of 350.
The next digit of our result is 7. 
Result so far: 20430.53578947
If we subtract 6650 from 7000, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Our division results in 20430.53578947 with a remaining 3.5e-07.
