Let's divide 399648 by 48
The aim is to understand the frequency of 48 in 399648.

On to step 1:
If we divide 3 by 48, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 48

Advancing to step 2:
If we divide 39 by 48, we get 0 and a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 48

On to step 3:
48 goes into 399 8 times with a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 384 from 399 leaves us with 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 48

On to step 4:
48 goes into 156 3 times with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
The remainder is 12 after subtracting 144 from 156.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 48

Going ahead to step 5:
48 goes into 124 2 times with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 832.0
If we take 96 away from 124, we end up with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 48

On to step 6:
The number 48 fits into 288 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 8326.0
The remainder is 0 after subtracting 288 from 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
48 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8326.0
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 8:
If we divide 0 by 48, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8326.0
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 quotient of the division is 8326.0, and the remainder is 0.0.
