Let's divide 516121 by 48
The aim is to understand the frequency of 48 in 516121.

Moving on to step 1:
When dividing 5 by 48, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 48

Step 2:
If we divide 51 by 48, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 48 from 51 and we're left with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 48

Advancing to step 3:
When dividing 36 by 48, we get 0 with a remainder of 36.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 36, we get 36.
Append the next digit (1) from the dividend to 36 and continue with: 361 / 48

Step 4:
When dividing 361 by 48, we get 7 with a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 107.0
Subtract 336 from 361 to get 25.
Grab the next digit (2) from the dividend, add it to 25, then carry on: 252 / 48

Advancing to step 5:
When dividing 252 by 48, we get 5 with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 1075.0
Subtract 240 from 252 to get 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 48

Moving on to step 6:
48 goes into 121 2 times with a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 10752.0
If we take 96 away from 121, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
If we divide 250 by 48, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 10752.5
Deduct 240 from 250 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
48 goes into 100 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 10752.52
Subtract 96 from 100 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
48 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 10752.52
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
48 can be fit into 400 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 10752.5208
If we subtract 384 from 400, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
The number 48 fits into 160 3 times, leaving a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 10752.52083
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
160 divided by 48 is 3 with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 10752.520833
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 10752.520833 with a remainder of 1.6e-06.
