27620848 ÷ 491 
The aim is to understand the frequency of 491 in 27620848.

Advancing to step 1:
2 divided by 491 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 491

Going ahead to step 2:
491 goes into 27 0 times with a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 27 leaves us with 27.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 491

Step 3:
276 divided by 491 is 0 with a remainder of 276.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 276 leaves us with 276.
Bring next digit (2) of the dividend behind the 276 and repeat the process: 2762 / 491

Going ahead to step 4:
The number 491 fits into 2762 5 times, leaving a remainder of 307.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 307 after subtracting 2455 from 2762.
Bring next digit (0) of the dividend behind the 307 and repeat the process: 3070 / 491

Step 5:
491 goes into 3070 6 times with a remainder of 124.
The next digit of our result is 6. 
Result so far: 56.0
Deduct 2946 from 3070 and we're left with 124.
Append the next digit (8) from the dividend to 124 and continue with: 1248 / 491

Let's proceed to step 6:
The number 491 fits into 1248 2 times, leaving a remainder of 266.
The number 2 becomes the next digit in our result. 
Result so far: 562.0
Deduct 982 from 1248 and we're left with 266.
Take the next digit (4) from the dividend and append it to 266, then repeat: 2664 / 491

Going ahead to step 7:
The number 491 fits into 2664 5 times, leaving a remainder of 209.
Record the quotient 5 as the next digit in the result. 
Result so far: 5625.0
The remainder is 209 after subtracting 2455 from 2664.
Grab the next digit (8) from the dividend, add it to 209, then carry on: 2098 / 491

Step 8:
When dividing 2098 by 491, we get 4 with a remainder of 134.
Put 4 as the next digit of the answer. 
Result so far: 56254.0
Deduct 1964 from 2098 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 9:
If we divide 1340 by 491, we get 2 and a remainder of 358.
The number 2 becomes the next digit in our result. 
Result so far: 56254.2
The remainder is 358 after subtracting 982 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Moving on to step 10:
3580 divided by 491 is 7 with a remainder of 143.
The number 7 becomes the next digit in our result. 
Result so far: 56254.27
If we take 3437 away from 3580, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Step 11:
The number 491 fits into 1430 2 times, leaving a remainder of 448.
The next digit of our result is 2. 
Result so far: 56254.272
The remainder is 448 after subtracting 982 from 1430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 12:
If we divide 4480 by 491, we get 9 and a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 56254.2729
Subtracting 4419 from 4480 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 13:
If we divide 610 by 491, we get 1 and a remainder of 119.
Use 1 as the next digit of our solution. 
Result so far: 56254.27291
If we take 491 away from 610, we end up with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Let's proceed to step 14:
491 goes into 1190 2 times with a remainder of 208.
The number 2 becomes the next digit in our result. 
Result so far: 56254.272912
Subtract 982 from 1190 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 15:
The number 491 fits into 2080 4 times, leaving a remainder of 116.
Put 4 as the next digit of the answer. 
Result so far: 56254.2729124
The remainder is 116 after subtracting 1964 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 16:
491 goes into 1160 2 times with a remainder of 178.
Put 2 as the next digit of the answer. 
Result so far: 56254.27291242
Deduct 982 from 1160 and we're left with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

After the division, we end up with 56254.27291242 and a remainder of 1.78e-07.
