We're dividing 490979 by 49 
The aim is to understand the frequency of 49 in 490979.

Moving on to step 1:
When dividing 4 by 49, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 49

On to step 2:
49 goes into 49 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we take 49 away from 49, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 49

Advancing to step 3:
The number 49 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 49

Step 4:
When dividing 9 by 49, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 49

Going ahead to step 5:
When dividing 97 by 49, we get 1 with a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 1001.0
Subtracting 49 from 97 leaves us with 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 49

Step 6:
489 divided by 49 is 9 with a remainder of 48.
The next digit of our result is 9. 
Result so far: 10019.0
Subtract 441 from 489 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 7:
480 divided by 49 is 9 with a remainder of 39.
The next digit of our result is 9. 
Result so far: 10019.9
Subtract 441 from 480 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 8:
The number 49 fits into 390 7 times, leaving a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 10019.97
Deduct 343 from 390 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 9:
If we divide 470 by 49, we get 9 and a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 10019.979
Subtract 441 from 470 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 10:
When dividing 290 by 49, we get 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 10019.9795
If we take 245 away from 290, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 11:
If we divide 450 by 49, we get 9 and a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 10019.97959
The remainder is 9 after subtracting 441 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 12:
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: 10019.979591
The remainder is 41 after subtracting 49 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 13:
If we divide 410 by 49, we get 8 and a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 10019.9795918
Subtracting 392 from 410 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 14:
When dividing 180 by 49, we get 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 10019.97959183
Subtracting 147 from 180 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

After the division, we end up with 10019.97959183 and a remainder of 3.3e-08.
