We divide 521359 by 49
The aim is to understand the frequency of 49 in 521359.

On to step 1:
When dividing 5 by 49, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 49

Going ahead to step 2:
49 goes into 52 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 49 from 52 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 49

Let's proceed to step 3:
If we divide 31 by 49, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 31 and we're left with 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 49

Going ahead to step 4:
313 divided by 49 is 6 with a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 106.0
Deduct 294 from 313 and we're left with 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 49

Step 5:
The number 49 fits into 195 3 times, leaving a remainder of 48.
The number 3 becomes the next digit in our result. 
Result so far: 1063.0
Subtracting 147 from 195 leaves us with 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 49

Going ahead to step 6:
489 divided by 49 is 9 with a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 10639.0
If we take 441 away from 489, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 7:
480 divided by 49 is 9 with a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 10639.9
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.

Advancing to step 8:
390 divided by 49 is 7 with a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 10639.97
The remainder is 47 after subtracting 343 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 9:
470 divided by 49 is 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 10639.979
Subtracting 441 from 470 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 10:
49 can be fit into 290 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 10639.9795
Deduct 245 from 290 and we're left 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.

Moving on to step 11:
49 can be fit into 450 9 times, resulting in a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 10639.97959
If we subtract 441 from 450, we get 9.
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.
The number 1 becomes the next digit in our result. 
Result so far: 10639.979591
If we take 49 away from 90, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 13:
410 divided by 49 is 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 10639.9795918
Subtract 392 from 410 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
49 goes into 180 3 times with a remainder of 33.
The next digit of our result is 3. 
Result so far: 10639.97959183
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.

The final result is 10639.97959183 with a remainder of 3.3e-08.
