Let's divide 819404 by 48
The aim is to understand the frequency of 48 in 819404.

Moving on to step 1:
8 divided by 48 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 48

Going ahead to step 2:
48 can be fit into 81 1 times, resulting in a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 33 after subtracting 48 from 81.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 48

Going ahead to step 3:
48 goes into 339 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 336 from 339 and we're left with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 48

Going ahead to step 4:
The number 48 fits into 34 0 times, leaving a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 170.0
Subtracting 0 from 34 leaves us with 34.
Append the next digit (0) from the dividend to 34 and continue with: 340 / 48

Let's proceed to step 5:
The number 48 fits into 340 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 1707.0
If we take 336 away from 340, we end up with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 48

Step 6:
When dividing 44 by 48, we get 0 with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 17070.0
Deduct 0 from 44 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 7:
If we divide 440 by 48, we get 9 and a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 17070.9
Deduct 432 from 440 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
48 can be fit into 80 1 times, resulting in a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 17070.91
If we take 48 away from 80, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
The number 48 fits into 320 6 times, leaving a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 17070.916
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
The number 48 fits into 320 6 times, leaving a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 17070.9166
Subtract 288 from 320 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 17070.9166, with a leftover of 0.00032.
