We divide 25816566 by 49
The aim is to understand the frequency of 49 in 25816566.

Let's proceed to step 1:
The number 49 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 49

On to step 2:
The number 49 fits into 25 0 times, leaving a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 49

On to step 3:
If we divide 258 by 49, we get 5 and a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 245 away from 258, we end up with 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 49

On to step 4:
131 divided by 49 is 2 with a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 52.0
If we take 98 away from 131, we end up with 33.
Include the next digit (6) from the dividend after 33, then repeat: 336 / 49

Moving on to step 5:
The number 49 fits into 336 6 times, leaving a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 526.0
Subtracting 294 from 336 leaves us with 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 49

On to step 6:
If we divide 425 by 49, we get 8 and a remainder of 33.
The number 8 becomes the next digit in our result. 
Result so far: 5268.0
If we take 392 away from 425, we end up with 33.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 49

Going ahead to step 7:
336 divided by 49 is 6 with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 52686.0
If we subtract 294 from 336, we get 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 49

On to step 8:
49 can be fit into 426 8 times, resulting in a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 526868.0
Deduct 392 from 426 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
The number 49 fits into 340 6 times, leaving a remainder of 46.
The next digit of our result is 6. 
Result so far: 526868.6
Subtracting 294 from 340 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 10:
If we divide 460 by 49, we get 9 and a remainder of 19.
The next digit of our result is 9. 
Result so far: 526868.69
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 11:
49 goes into 190 3 times with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 526868.693
If we take 147 away from 190, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 12:
49 goes into 430 8 times with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 526868.6938
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.

On to step 13:
The number 49 fits into 380 7 times, leaving a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 526868.69387
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.

Going ahead to step 14:
When dividing 370 by 49, we get 7 with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 526868.693877
Subtracting 343 from 370 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 526868.693877 and a remainder of 2.7e-06.
