Let's divide 257531 by 49
The aim is to understand the frequency of 49 in 257531.

Going ahead to step 1:
49 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 49

Advancing to step 2:
If we divide 25 by 49, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Include the next digit (7) from the dividend after 25, then repeat: 257 / 49

Step 3:
49 can be fit into 257 5 times, resulting in a remainder of 12.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 245 from 257 and we're left with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 49

Let's proceed to step 4:
49 goes into 125 2 times with a remainder of 27.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we take 98 away from 125, we end up with 27.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 49

Advancing to step 5:
If we divide 273 by 49, we get 5 and a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 525.0
If we take 245 away from 273, we end up with 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 49

On to step 6:
If we divide 281 by 49, we get 5 and a remainder of 36.
The next digit of our result is 5. 
Result so far: 5255.0
If we subtract 245 from 281, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
360 divided by 49 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 5255.7
Deduct 343 from 360 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 8:
The number 49 fits into 170 3 times, leaving a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 5255.73
Subtract 147 from 170 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 9:
The number 49 fits into 230 4 times, leaving a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 5255.734
If we subtract 196 from 230, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
340 divided by 49 is 6 with a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 5255.7346
Subtract 294 from 340 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
49 can be fit into 460 9 times, resulting in a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 5255.73469
Subtracting 441 from 460 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 12:
If we divide 190 by 49, we get 3 and a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 5255.734693
If we subtract 147 from 190, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 13:
49 goes into 430 8 times with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 5255.7346938
Subtracting 392 from 430 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 14:
When dividing 380 by 49, we get 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 5255.73469387
The remainder is 37 after subtracting 343 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

After the division, we end up with 5255.73469387 and a remainder of 3.7e-08.
