513312 ÷ 49 
The aim is to understand the frequency of 49 in 513312.

Going ahead to step 1:
When dividing 5 by 49, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 49

On to step 2:
If we divide 51 by 49, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 49 from 51 leaves us with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 49

Moving on to step 3:
When dividing 23 by 49, we get 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 23 to get 23.
Bring next digit (3) of the dividend behind the 23 and repeat the process: 233 / 49

Moving on to step 4:
49 goes into 233 4 times with a remainder of 37.
Write down 4 as next digit of the result. 
Result so far: 104.0
Subtract 196 from 233 to get 37.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 49

Step 5:
When dividing 371 by 49, we get 7 with a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 1047.0
Deduct 343 from 371 and we're left with 28.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 49

Let's proceed to step 6:
282 divided by 49 is 5 with a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 10475.0
Deduct 245 from 282 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
The number 49 fits into 370 7 times, leaving a remainder of 27.
The next digit of our result is 7. 
Result so far: 10475.7
The remainder is 27 after subtracting 343 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 8:
If we divide 270 by 49, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 10475.75
If we subtract 245 from 270, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
250 divided by 49 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 10475.755
Subtracting 245 from 250 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 10475.755 with a remaining 0.0005.
