We're dividing 15625747 by 491 
The aim is to understand the frequency of 491 in 15625747.

Step 1:
491 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 491

On to step 2:
15 divided by 491 is 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 491

Advancing to step 3:
When dividing 156 by 491, we get 0 with a remainder of 156.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 156 to get 156.
Bring next digit (2) of the dividend behind the 156 and repeat the process: 1562 / 491

Step 4:
When dividing 1562 by 491, we get 3 with a remainder of 89.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 89 after subtracting 1473 from 1562.
Fetch the next digit (5) from the dividend, attach it to 89 and continue: 895 / 491

Moving on to step 5:
895 divided by 491 is 1 with a remainder of 404.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we take 491 away from 895, we end up with 404.
Take the next digit (7) from the dividend and append it to 404, then repeat: 4047 / 491

Advancing to step 6:
If we divide 4047 by 491, we get 8 and a remainder of 119.
Use 8 as the next digit of our solution. 
Result so far: 318.0
Subtracting 3928 from 4047 leaves us with 119.
Take the next digit (4) from the dividend and append it to 119, then repeat: 1194 / 491

Step 7:
When dividing 1194 by 491, we get 2 with a remainder of 212.
Record the quotient 2 as the next digit in the result. 
Result so far: 3182.0
Deduct 982 from 1194 and we're left with 212.
Include the next digit (7) from the dividend after 212, then repeat: 2127 / 491

Advancing to step 8:
If we divide 2127 by 491, we get 4 and a remainder of 163.
Write down 4 as next digit of the result. 
Result so far: 31824.0
The remainder is 163 after subtracting 1964 from 2127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Step 9:
1630 divided by 491 is 3 with a remainder of 157.
Put 3 as the next digit of the answer. 
Result so far: 31824.3
Deduct 1473 from 1630 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 10:
If we divide 1570 by 491, we get 3 and a remainder of 97.
Use 3 as the next digit of our solution. 
Result so far: 31824.33
Subtracting 1473 from 1570 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Our division results in 31824.33 with a remaining 0.097.
