We divide 391902 by 48
The aim is to understand the frequency of 48 in 391902.

Moving on to step 1:
When dividing 3 by 48, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 48

Let's proceed to step 2:
39 divided by 48 is 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 48

Let's proceed to step 3:
48 goes into 391 8 times with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 384 from 391 and we're left with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 48

Moving on to step 4:
When dividing 79 by 48, we get 1 with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 81.0
The remainder is 31 after subtracting 48 from 79.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 48

Let's proceed to step 5:
The number 48 fits into 310 6 times, leaving a remainder of 22.
The next digit of our result is 6. 
Result so far: 816.0
Deduct 288 from 310 and we're left with 22.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 48

Advancing to step 6:
When dividing 222 by 48, we get 4 with a remainder of 30.
The next digit of our result is 4. 
Result so far: 8164.0
Subtract 192 from 222 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
300 divided by 48 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 8164.6
Subtract 288 from 300 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
If we divide 120 by 48, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 8164.62
If we take 96 away from 120, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
48 goes into 240 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8164.625
Subtract 240 from 240 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.

Step 10:
When dividing 0 by 48, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8164.625
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.

Moving on to step 11:
48 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8164.625
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 result is 8164.625 with a remainder of 0.0.
