We're dividing 4320841 by 491 
The aim is to understand the frequency of 491 in 4320841.

On to step 1:
4 divided by 491 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 491

Step 2:
When dividing 43 by 491, we get 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Grab the next digit (2) from the dividend, add it to 43, then carry on: 432 / 491

Step 3:
The number 491 fits into 432 0 times, leaving a remainder of 432.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 432 after subtracting 0 from 432.
Take the next digit (0) from the dividend and append it to 432, then repeat: 4320 / 491

Advancing to step 4:
4320 divided by 491 is 8 with a remainder of 392.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 3928 from 4320, we get 392.
Bring next digit (8) of the dividend behind the 392 and repeat the process: 3928 / 491

Going ahead to step 5:
491 can be fit into 3928 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 88.0
The remainder is 0 after subtracting 3928 from 3928.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 491

Step 6:
The number 491 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 880.0
Subtract 0 from 4 to get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 491

On to step 7:
The number 491 fits into 41 0 times, leaving a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 8800.0
Subtracting 0 from 41 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 8:
491 can be fit into 410 0 times, resulting in a remainder of 410.
Put 0 as the next digit of the answer. 
Result so far: 8800.0
If we subtract 0 from 410, we get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 9:
If we divide 4100 by 491, we get 8 and a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 8800.08
The remainder is 172 after subtracting 3928 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 10:
When dividing 1720 by 491, we get 3 with a remainder of 247.
The number 3 becomes the next digit in our result. 
Result so far: 8800.083
Deduct 1473 from 1720 and we're left with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

On to step 11:
When dividing 2470 by 491, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 8800.0835
Subtract 2455 from 2470 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
491 goes into 150 0 times with a remainder of 150.
The next digit of our result is 0. 
Result so far: 8800.0835
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 13:
1500 divided by 491 is 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 8800.083503
Subtract 1473 from 1500 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 14:
When dividing 270 by 491, we get 0 with a remainder of 270.
Use 0 as the next digit of our solution. 
Result so far: 8800.083503
Subtract 0 from 270 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 15:
If we divide 2700 by 491, we get 5 and a remainder of 245.
Write down 5 as next digit of the result. 
Result so far: 8800.08350305
Subtract 2455 from 2700 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

After the division, we end up with 8800.08350305 and a remainder of 2.45e-07.
