We're dividing 513527 by 49 
The aim is to understand the frequency of 49 in 513527.

Advancing to step 1:
5 divided by 49 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 49

Moving on to step 2:
51 divided by 49 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 49 from 51 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 49

Moving on to step 3:
If we divide 23 by 49, we get 0 and a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 23 and we're left with 23.
Grab the next digit (5) from the dividend, add it to 23, then carry on: 235 / 49

Going ahead to step 4:
If we divide 235 by 49, we get 4 and a remainder of 39.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
Subtract 196 from 235 to get 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 49

Step 5:
If we divide 392 by 49, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 1048.0
Subtract 392 from 392 to get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 49

On to step 6:
If we divide 7 by 49, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 10480.0
Subtracting 0 from 7 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
If we divide 70 by 49, we get 1 and a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 10480.1
If we subtract 49 from 70, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 8:
49 goes into 210 4 times with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 10480.14
Subtract 196 from 210 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
140 divided by 49 is 2 with a remainder of 42.
The next digit of our result is 2. 
Result so far: 10480.142
Subtract 98 from 140 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
49 goes into 420 8 times with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 10480.1428
If we take 392 away from 420, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
When dividing 280 by 49, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 10480.14285
If we subtract 245 from 280, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 12:
The number 49 fits into 350 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 10480.142857
Deduct 343 from 350 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 13:
The number 49 fits into 70 1 times, leaving a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 10480.1428571
If we take 49 away from 70, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 14:
49 goes into 210 4 times with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 10480.14285714
Deduct 196 from 210 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 10480.14285714, with a leftover of 1.4e-08.
