We look at the division of 55978 by 49 
The aim is to understand the frequency of 49 in 55978.

Step 1:
If we divide 5 by 49, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 49

Going ahead to step 2:
If we divide 55 by 49, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 49 from 55, we get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 49

Going ahead to step 3:
If we divide 69 by 49, we get 1 and a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 49 from 69 leaves us with 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 49

On to step 4:
207 divided by 49 is 4 with a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
If we take 196 away from 207, we end up with 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 49

Step 5:
118 divided by 49 is 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 1142.0
Subtracting 98 from 118 leaves us 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.

Going ahead to step 6:
If we divide 200 by 49, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 1142.4
If we take 196 away from 200, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
The number 49 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1142.4
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
If we divide 400 by 49, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 1142.408
Subtracting 392 from 400 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
If we divide 80 by 49, we get 1 and a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 1142.4081
If we take 49 away from 80, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 10:
49 goes into 310 6 times with a remainder of 16.
The next digit of our result is 6. 
Result so far: 1142.40816
Subtracting 294 from 310 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
49 can be fit into 160 3 times, resulting in a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 1142.408163
Deduct 147 from 160 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 12:
When dividing 130 by 49, we get 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 1142.4081632
Subtract 98 from 130 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
If we divide 320 by 49, we get 6 and a remainder of 26.
The next digit of our result is 6. 
Result so far: 1142.40816326
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 1142.40816326 with a remainder of 2.6e-08.
