Let's divide 809919 by 48
The aim is to understand the frequency of 48 in 809919.

On to step 1:
8 divided by 48 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 48

On to step 2:
80 divided by 48 is 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 48 from 80 to get 32.
Take the next digit (9) from the dividend and append it to 32, then repeat: 329 / 48

Let's proceed to step 3:
48 goes into 329 6 times with a remainder of 41.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 288 from 329 leaves us with 41.
Append the next digit (9) from the dividend to 41 and continue with: 419 / 48

Going ahead to step 4:
The number 48 fits into 419 8 times, leaving a remainder of 35.
Write down 8 as next digit of the result. 
Result so far: 168.0
Deduct 384 from 419 and we're left with 35.
Append the next digit (1) from the dividend to 35 and continue with: 351 / 48

Moving on to step 5:
If we divide 351 by 48, we get 7 and a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 1687.0
Deduct 336 from 351 and we're left with 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 48

Going ahead to step 6:
159 divided by 48 is 3 with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 16873.0
If we take 144 away from 159, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
The number 48 fits into 150 3 times, leaving a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 16873.3
The remainder is 6 after subtracting 144 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
60 divided by 48 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 16873.31
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.

Moving on to step 9:
120 divided by 48 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 16873.312
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.

Moving on to step 10:
If we divide 240 by 48, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 16873.3125
Subtracting 240 from 240 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 11:
48 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 16873.3125
If we take 0 away from 0, we end up 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:
48 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16873.3125
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.

The quotient of the division is 16873.3125, and the remainder is 0.0.
