We look at the division of 570611 by 49 
The aim is to understand the frequency of 49 in 570611.

Step 1:
If we divide 5 by 49, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 49

Moving on to step 2:
When dividing 57 by 49, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 49 from 57, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 49

Let's proceed to step 3:
When dividing 80 by 49, we get 1 with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 49 from 80, we get 31.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 49

Let's proceed to step 4:
If we divide 316 by 49, we get 6 and a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 116.0
Subtracting 294 from 316 leaves us with 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 49

Moving on to step 5:
49 can be fit into 221 4 times, resulting in a remainder of 25.
The next digit of our result is 4. 
Result so far: 1164.0
The remainder is 25 after subtracting 196 from 221.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 49

Advancing to step 6:
49 can be fit into 251 5 times, resulting in a remainder of 6.
The next digit of our result is 5. 
Result so far: 11645.0
If we subtract 245 from 251, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
The number 49 fits into 60 1 times, leaving a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 11645.1
If we subtract 49 from 60, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
The number 49 fits into 110 2 times, leaving a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 11645.12
If we subtract 98 from 110, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
The number 49 fits into 120 2 times, leaving a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 11645.122
Subtract 98 from 120 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 11645.122 and a remainder of 0.0022.
