We divide 909421 by 49
The aim is to understand the frequency of 49 in 909421.

Moving on to step 1:
The number 49 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 49

Moving on to step 2:
The number 49 fits into 90 1 times, leaving a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 49 from 90, we get 41.
Append the next digit (9) from the dividend to 41 and continue with: 419 / 49

Going ahead to step 3:
49 goes into 419 8 times with a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 392 from 419 and we're left with 27.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 49

On to step 4:
274 divided by 49 is 5 with a remainder of 29.
Write down 5 as next digit of the result. 
Result so far: 185.0
Subtract 245 from 274 to get 29.
Take the next digit (2) from the dividend and append it to 29, then repeat: 292 / 49

On to step 5:
The number 49 fits into 292 5 times, leaving a remainder of 47.
Record the quotient 5 as the next digit in the result. 
Result so far: 1855.0
The remainder is 47 after subtracting 245 from 292.
Take the next digit (1) from the dividend and append it to 47, then repeat: 471 / 49

Going ahead to step 6:
The number 49 fits into 471 9 times, leaving a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 18559.0
If we take 441 away from 471, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
49 goes into 300 6 times with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 18559.6
Subtract 294 from 300 to 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.

Moving on to step 8:
49 goes into 60 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 18559.61
If we take 49 away from 60, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
49 goes into 110 2 times with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 18559.612
Subtract 98 from 110 to 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.

Going ahead to step 10:
49 goes into 120 2 times with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 18559.6122
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.

Our division results in 18559.6122 with a remaining 0.00022.
