We look at the division of 30965145 by 491 
The aim is to understand the frequency of 491 in 30965145.

Advancing to step 1:
When dividing 3 by 491, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 491

Let's proceed to step 2:
491 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 491

Moving on to step 3:
The number 491 fits into 309 0 times, leaving a remainder of 309.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 309 to get 309.
Append the next digit (6) from the dividend to 309 and continue with: 3096 / 491

Going ahead to step 4:
If we divide 3096 by 491, we get 6 and a remainder of 150.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 2946 from 3096 and we're left with 150.
Fetch the next digit (5) from the dividend, attach it to 150 and continue: 1505 / 491

Moving on to step 5:
491 goes into 1505 3 times with a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 63.0
The remainder is 32 after subtracting 1473 from 1505.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 491

Going ahead to step 6:
491 can be fit into 321 0 times, resulting in a remainder of 321.
Put 0 as the next digit of the answer. 
Result so far: 630.0
If we take 0 away from 321, we end up with 321.
Fetch the next digit (4) from the dividend, attach it to 321 and continue: 3214 / 491

Going ahead to step 7:
3214 divided by 491 is 6 with a remainder of 268.
Record the quotient 6 as the next digit in the result. 
Result so far: 6306.0
Subtracting 2946 from 3214 leaves us with 268.
Append the next digit (5) from the dividend to 268 and continue with: 2685 / 491

Let's proceed to step 8:
If we divide 2685 by 491, we get 5 and a remainder of 230.
Record the quotient 5 as the next digit in the result. 
Result so far: 63065.0
Deduct 2455 from 2685 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 9:
491 can be fit into 2300 4 times, resulting in a remainder of 336.
The next digit of our result is 4. 
Result so far: 63065.4
Subtracting 1964 from 2300 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 10:
3360 divided by 491 is 6 with a remainder of 414.
Use 6 as the next digit of our solution. 
Result so far: 63065.46
If we subtract 2946 from 3360, we get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 11:
If we divide 4140 by 491, we get 8 and a remainder of 212.
Write down 8 as next digit of the result. 
Result so far: 63065.468
Subtract 3928 from 4140 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 12:
2120 divided by 491 is 4 with a remainder of 156.
The number 4 becomes the next digit in our result. 
Result so far: 63065.4684
The remainder is 156 after subtracting 1964 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 13:
When dividing 1560 by 491, we get 3 with a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 63065.46843
The remainder is 87 after subtracting 1473 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 14:
491 can be fit into 870 1 times, resulting in a remainder of 379.
Use 1 as the next digit of our solution. 
Result so far: 63065.468431
Subtract 491 from 870 to get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Moving on to step 15:
491 goes into 3790 7 times with a remainder of 353.
Put 7 as the next digit of the answer. 
Result so far: 63065.4684317
If we subtract 3437 from 3790, we get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Going ahead to step 16:
The number 491 fits into 3530 7 times, leaving a remainder of 93.
Put 7 as the next digit of the answer. 
Result so far: 63065.46843177
If we take 3437 away from 3530, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

The final outcome is 63065.46843177, with a leftover of 9.3e-08.
