15033183 divided by 491 
The aim is to understand the frequency of 491 in 15033183.

Let's proceed to step 1:
491 goes into 1 0 times with 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.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 491

Step 2:
When dividing 15 by 491, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 491

Moving on to step 3:
If we divide 150 by 491, we get 0 and a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 150 to get 150.
Append the next digit (3) from the dividend to 150 and continue with: 1503 / 491

Going ahead to step 4:
491 goes into 1503 3 times with a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 1473 from 1503 leaves us with 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 491

On to step 5:
303 divided by 491 is 0 with a remainder of 303.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we subtract 0 from 303, we get 303.
Include the next digit (1) from the dividend after 303, then repeat: 3031 / 491

Moving on to step 6:
491 goes into 3031 6 times with a remainder of 85.
Write down 6 as next digit of the result. 
Result so far: 306.0
The remainder is 85 after subtracting 2946 from 3031.
Bring next digit (8) of the dividend behind the 85 and repeat the process: 858 / 491

On to step 7:
If we divide 858 by 491, we get 1 and a remainder of 367.
Use 1 as the next digit of our solution. 
Result so far: 3061.0
Subtracting 491 from 858 leaves us with 367.
Bring next digit (3) of the dividend behind the 367 and repeat the process: 3673 / 491

On to step 8:
The number 491 fits into 3673 7 times, leaving a remainder of 236.
Record the quotient 7 as the next digit in the result. 
Result so far: 30617.0
Subtract 3437 from 3673 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 9:
If we divide 2360 by 491, we get 4 and a remainder of 396.
Put 4 as the next digit of the answer. 
Result so far: 30617.4
Deduct 1964 from 2360 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Going ahead to step 10:
The number 491 fits into 3960 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 30617.48
If we subtract 3928 from 3960, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
If we divide 320 by 491, we get 0 and a remainder of 320.
The next digit of our result is 0. 
Result so far: 30617.48
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 12:
When dividing 3200 by 491, we get 6 with a remainder of 254.
The next digit of our result is 6. 
Result so far: 30617.4806
Deduct 2946 from 3200 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 13:
491 goes into 2540 5 times with a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 30617.48065
Subtracting 2455 from 2540 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 14:
If we divide 850 by 491, we get 1 and a remainder of 359.
Put 1 as the next digit of the answer. 
Result so far: 30617.480651
Subtracting 491 from 850 leaves us with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Step 15:
When dividing 3590 by 491, we get 7 with a remainder of 153.
Put 7 as the next digit of the answer. 
Result so far: 30617.4806517
Subtracting 3437 from 3590 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 16:
When dividing 1530 by 491, we get 3 with a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 30617.48065173
Deduct 1473 from 1530 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The final outcome is 30617.48065173, with a leftover of 5.7e-08.
