We look at the division of 375709 by 48 
The aim is to understand the frequency of 48 in 375709.

Let's proceed to step 1:
When dividing 3 by 48, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 48

Moving on to step 2:
The number 48 fits into 37 0 times, leaving a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 48

Going ahead to step 3:
When dividing 375 by 48, we get 7 with a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 336 from 375 to get 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 48

Moving on to step 4:
397 divided by 48 is 8 with a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
The remainder is 13 after subtracting 384 from 397.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 48

Moving on to step 5:
When dividing 130 by 48, we get 2 with a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 782.0
If we subtract 96 from 130, we get 34.
Take the next digit (9) from the dividend and append it to 34, then repeat: 349 / 48

On to step 6:
The number 48 fits into 349 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 7827.0
Subtract 336 from 349 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
If we divide 130 by 48, we get 2 and a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 7827.2
The remainder is 34 after subtracting 96 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
The number 48 fits into 340 7 times, leaving a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 7827.27
If we take 336 away from 340, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
40 divided by 48 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 7827.27
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
400 divided by 48 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 7827.2708
Subtracting 384 from 400 leaves us 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.

Let's proceed to step 11:
When dividing 160 by 48, we get 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 7827.27083
Subtracting 144 from 160 leaves us 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.

Advancing to step 12:
The number 48 fits into 160 3 times, leaving a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 7827.270833
The remainder is 16 after subtracting 144 from 160.
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 7827.270833 with a remainder of 1.6e-06.
