We look at the division of 55543021 by 491 
The aim is to understand the frequency of 491 in 55543021.

On to step 1:
If we divide 5 by 491, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 491

Going ahead to step 2:
When dividing 55 by 491, we get 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Include the next digit (5) from the dividend after 55, then repeat: 555 / 491

Let's proceed to step 3:
491 can be fit into 555 1 times, resulting in a remainder of 64.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 491 from 555 to get 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 491

Advancing to step 4:
When dividing 644 by 491, we get 1 with a remainder of 153.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 153 after subtracting 491 from 644.
Grab the next digit (3) from the dividend, add it to 153, then carry on: 1533 / 491

Advancing to step 5:
491 can be fit into 1533 3 times, resulting in a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 113.0
If we subtract 1473 from 1533, we get 60.
Include the next digit (0) from the dividend after 60, then repeat: 600 / 491

Let's proceed to step 6:
The number 491 fits into 600 1 times, leaving a remainder of 109.
Put 1 as the next digit of the answer. 
Result so far: 1131.0
Subtract 491 from 600 to get 109.
Append the next digit (2) from the dividend to 109 and continue with: 1092 / 491

Advancing to step 7:
491 goes into 1092 2 times with a remainder of 110.
Record the quotient 2 as the next digit in the result. 
Result so far: 11312.0
The remainder is 110 after subtracting 982 from 1092.
Bring next digit (1) of the dividend behind the 110 and repeat the process: 1101 / 491

Advancing to step 8:
When dividing 1101 by 491, we get 2 with a remainder of 119.
Put 2 as the next digit of the answer. 
Result so far: 113122.0
Subtract 982 from 1101 to get 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 9:
When dividing 1190 by 491, we get 2 with a remainder of 208.
Record the quotient 2 as the next digit in the result. 
Result so far: 113122.2
Deduct 982 from 1190 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 10:
491 can be fit into 2080 4 times, resulting in a remainder of 116.
Use 4 as the next digit of our solution. 
Result so far: 113122.24
Subtract 1964 from 2080 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 11:
491 goes into 1160 2 times with a remainder of 178.
Use 2 as the next digit of our solution. 
Result so far: 113122.242
Subtracting 982 from 1160 leaves us 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.

Advancing to step 12:
491 can be fit into 1780 3 times, resulting in a remainder of 307.
Write down 3 as next digit of the result. 
Result so far: 113122.2423
Subtract 1473 from 1780 to get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Going ahead to step 13:
The number 491 fits into 3070 6 times, leaving a remainder of 124.
Write down 6 as next digit of the result. 
Result so far: 113122.24236
Subtract 2946 from 3070 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 14:
491 goes into 1240 2 times with a remainder of 258.
The next digit of our result is 2. 
Result so far: 113122.242362
Deduct 982 from 1240 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 15:
491 can be fit into 2580 5 times, resulting in a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 113122.2423625
Deduct 2455 from 2580 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 16:
If we divide 1250 by 491, we get 2 and a remainder of 268.
Put 2 as the next digit of the answer. 
Result so far: 113122.24236252
Subtracting 982 from 1250 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

The quotient of the division is 113122.24236252, and the remainder is 2.68e-07.
