Let's divide 525015 by 49
The aim is to understand the frequency of 49 in 525015.

Going ahead to step 1:
The number 49 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 49

Step 2:
If we divide 52 by 49, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 49 from 52 to get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 49

Moving on to step 3:
If we divide 35 by 49, we get 0 and a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 35 to get 35.
Include the next digit (0) from the dividend after 35, then repeat: 350 / 49

Going ahead to step 4:
When dividing 350 by 49, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 107.0
Deduct 343 from 350 and we're left with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 49

Advancing to step 5:
49 goes into 71 1 times with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1071.0
The remainder is 22 after subtracting 49 from 71.
Take the next digit (5) from the dividend and append it to 22, then repeat: 225 / 49

On to step 6:
49 can be fit into 225 4 times, resulting in a remainder of 29.
The number 4 becomes the next digit in our result. 
Result so far: 10714.0
If we subtract 196 from 225, we 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 7:
290 divided by 49 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 10714.5
The remainder is 45 after subtracting 245 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 8:
49 can be fit into 450 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 10714.59
Deduct 441 from 450 and we're left with 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 9:
When dividing 90 by 49, we get 1 with a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 10714.591
Deduct 49 from 90 and we're left 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.

Moving on to step 10:
The number 49 fits into 410 8 times, leaving a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 10714.5918
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.

Step 11:
180 divided by 49 is 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 10714.59183
If we take 147 away from 180, we end up 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.

Step 12:
330 divided by 49 is 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 10714.591836
The remainder is 36 after subtracting 294 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
49 can be fit into 360 7 times, resulting in a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 10714.5918367
Subtract 343 from 360 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 14:
49 can be fit into 170 3 times, resulting in a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 10714.59183673
If we take 147 away from 170, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The quotient of the division is 10714.59183673, and the remainder is 2.3e-08.
