We're dividing 839874 by 48 
The aim is to understand the frequency of 48 in 839874.

Advancing to step 1:
48 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 48

Moving on to step 2:
When dividing 83 by 48, we get 1 with a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 48 from 83 to get 35.
Bring next digit (9) of the dividend behind the 35 and repeat the process: 359 / 48

Step 3:
The number 48 fits into 359 7 times, leaving a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtracting 336 from 359 leaves us with 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 48

Going ahead to step 4:
If we divide 238 by 48, we get 4 and a remainder of 46.
The next digit of our result is 4. 
Result so far: 174.0
Deduct 192 from 238 and we're left with 46.
Take the next digit (7) from the dividend and append it to 46, then repeat: 467 / 48

Moving on to step 5:
The number 48 fits into 467 9 times, leaving a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 1749.0
Deduct 432 from 467 and we're left with 35.
Bring next digit (4) of the dividend behind the 35 and repeat the process: 354 / 48

Advancing to step 6:
48 goes into 354 7 times with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 17497.0
If we take 336 away from 354, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
The number 48 fits into 180 3 times, leaving a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 17497.3
If we take 144 away from 180, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
48 goes into 360 7 times with a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 17497.37
Subtract 336 from 360 to 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.

On to step 9:
When dividing 240 by 48, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 17497.375
The remainder is 0 after subtracting 240 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
The number 48 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17497.375
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.

Moving on to step 11:
If we divide 0 by 48, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 17497.375
The remainder is 0 after subtracting 0 from 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 quotient of the division is 17497.375, and the remainder is 0.0.
