We're dividing 858044 by 49 
The aim is to understand the frequency of 49 in 858044.

On to step 1:
If we divide 8 by 49, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 49

Moving on to step 2:
49 can be fit into 85 1 times, resulting in a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 49 from 85 to get 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 49

Moving on to step 3:
368 divided by 49 is 7 with a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 343 from 368 and we're left with 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 49

Going ahead to step 4:
If we divide 250 by 49, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 175.0
Subtracting 245 from 250 leaves us with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 49

Advancing to step 5:
49 goes into 54 1 times with a remainder of 5.
The next digit of our result is 1. 
Result so far: 1751.0
If we subtract 49 from 54, we get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 49

Advancing to step 6:
54 divided by 49 is 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 17511.0
If we subtract 49 from 54, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
50 divided by 49 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 17511.1
If we subtract 49 from 50, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
If we divide 10 by 49, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 17511.1
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
49 can be fit into 100 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 17511.102
Deduct 98 from 100 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
When dividing 20 by 49, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 17511.102
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
The number 49 fits into 200 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 17511.10204
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
When dividing 40 by 49, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 17511.10204
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
When dividing 400 by 49, we get 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 17511.1020408
If we subtract 392 from 400, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
49 can be fit into 80 1 times, resulting in a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 17511.10204081
Subtract 49 from 80 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final outcome is 17511.10204081, with a leftover of 3.1e-08.
