Let's divide 138759 by 48
The aim is to understand the frequency of 48 in 138759.

On to step 1:
48 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 48

Step 2:
13 divided by 48 is 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 48

Advancing to step 3:
48 goes into 138 2 times with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 96 from 138, we get 42.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 48

On to step 4:
427 divided by 48 is 8 with a remainder of 43.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtract 384 from 427 to get 43.
Fetch the next digit (5) from the dividend, attach it to 43 and continue: 435 / 48

Advancing to step 5:
The number 48 fits into 435 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 289.0
If we take 432 away from 435, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 48

On to step 6:
When dividing 39 by 48, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 2890.0
The remainder is 39 after subtracting 0 from 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
48 can be fit into 390 8 times, resulting in a remainder of 6.
The next digit of our result is 8. 
Result so far: 2890.8
Subtracting 384 from 390 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
60 divided by 48 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 2890.81
Deduct 48 from 60 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
48 can be fit into 120 2 times, resulting in a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 2890.812
If we subtract 96 from 120, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
48 goes into 240 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2890.8125
If we subtract 240 from 240, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
When dividing 0 by 48, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2890.8125
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
If we divide 0 by 48, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2890.8125
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 2890.8125, with a leftover of 0.0.
