Let's divide 39149086 by 303
The aim is to understand the frequency of 303 in 39149086.

Going ahead to step 1:
When dividing 3 by 303, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 303

Moving on to step 2:
When dividing 39 by 303, we get 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 303

Advancing to step 3:
303 can be fit into 391 1 times, resulting in a remainder of 88.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 88 after subtracting 303 from 391.
Include the next digit (4) from the dividend after 88, then repeat: 884 / 303

On to step 4:
The number 303 fits into 884 2 times, leaving a remainder of 278.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 606 from 884 to get 278.
Bring next digit (9) of the dividend behind the 278 and repeat the process: 2789 / 303

Let's proceed to step 5:
303 goes into 2789 9 times with a remainder of 62.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
The remainder is 62 after subtracting 2727 from 2789.
Take the next digit (0) from the dividend and append it to 62, then repeat: 620 / 303

Advancing to step 6:
If we divide 620 by 303, we get 2 and a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 1292.0
If we subtract 606 from 620, we get 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 303

Advancing to step 7:
The number 303 fits into 148 0 times, leaving a remainder of 148.
Use 0 as the next digit of our solution. 
Result so far: 12920.0
Subtracting 0 from 148 leaves us with 148.
Fetch the next digit (6) from the dividend, attach it to 148 and continue: 1486 / 303

Step 8:
The number 303 fits into 1486 4 times, leaving a remainder of 274.
Record the quotient 4 as the next digit in the result. 
Result so far: 129204.0
If we subtract 1212 from 1486, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 9:
303 goes into 2740 9 times with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 129204.9
Subtracting 2727 from 2740 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 10:
303 can be fit into 130 0 times, resulting in a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 129204.9
Subtract 0 from 130 to 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.

Advancing to step 11:
303 can be fit into 1300 4 times, resulting in a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 129204.904
The remainder is 88 after subtracting 1212 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 12:
The number 303 fits into 880 2 times, leaving a remainder of 274.
Put 2 as the next digit of the answer. 
Result so far: 129204.9042
Deduct 606 from 880 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 13:
When dividing 2740 by 303, we get 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 129204.90429
If we subtract 2727 from 2740, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 14:
When dividing 130 by 303, we get 0 with a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 129204.90429
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 15:
303 can be fit into 1300 4 times, resulting in a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 129204.9042904
If we subtract 1212 from 1300, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 16:
880 divided by 303 is 2 with a remainder of 274.
Put 2 as the next digit of the answer. 
Result so far: 129204.90429042
Subtract 606 from 880 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Our division results in 129204.90429042 with a remaining 2.74e-07.
