We divide 29581984 by 491
The aim is to understand the frequency of 491 in 29581984.

Advancing to step 1:
If we divide 2 by 491, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 491

Advancing to step 2:
491 can be fit into 29 0 times, resulting in a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Append the next digit (5) from the dividend to 29 and continue with: 295 / 491

Advancing to step 3:
If we divide 295 by 491, we get 0 and a remainder of 295.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 295, we get 295.
Grab the next digit (8) from the dividend, add it to 295, then carry on: 2958 / 491

On to step 4:
If we divide 2958 by 491, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 6.0
If we take 2946 away from 2958, we end up with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 491

Moving on to step 5:
491 goes into 121 0 times with a remainder of 121.
Use 0 as the next digit of our solution. 
Result so far: 60.0
Deduct 0 from 121 and we're left with 121.
Bring next digit (9) of the dividend behind the 121 and repeat the process: 1219 / 491

On to step 6:
If we divide 1219 by 491, we get 2 and a remainder of 237.
Use 2 as the next digit of our solution. 
Result so far: 602.0
Deduct 982 from 1219 and we're left with 237.
Take the next digit (8) from the dividend and append it to 237, then repeat: 2378 / 491

Moving on to step 7:
If we divide 2378 by 491, we get 4 and a remainder of 414.
Use 4 as the next digit of our solution. 
Result so far: 6024.0
If we take 1964 away from 2378, we end up with 414.
Fetch the next digit (4) from the dividend, attach it to 414 and continue: 4144 / 491

Step 8:
491 can be fit into 4144 8 times, resulting in a remainder of 216.
Use 8 as the next digit of our solution. 
Result so far: 60248.0
Deduct 3928 from 4144 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 9:
When dividing 2160 by 491, we get 4 with a remainder of 196.
Write down 4 as next digit of the result. 
Result so far: 60248.4
If we take 1964 away from 2160, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 10:
1960 divided by 491 is 3 with a remainder of 487.
The number 3 becomes the next digit in our result. 
Result so far: 60248.43
Deduct 1473 from 1960 and we're left with 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Going ahead to step 11:
491 can be fit into 4870 9 times, resulting in a remainder of 451.
Put 9 as the next digit of the answer. 
Result so far: 60248.439
The remainder is 451 after subtracting 4419 from 4870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Let's proceed to step 12:
491 can be fit into 4510 9 times, resulting in a remainder of 91.
The next digit of our result is 9. 
Result so far: 60248.4399
The remainder is 91 after subtracting 4419 from 4510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

The final outcome is 60248.4399, with a leftover of 0.00091.
