We look at the division of 423517 by 48 
The aim is to understand the frequency of 48 in 423517.

Let's proceed to step 1:
48 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 48

Step 2:
48 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 48

Advancing to step 3:
48 can be fit into 423 8 times, resulting in a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 384 from 423, we get 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 48

Going ahead to step 4:
395 divided by 48 is 8 with a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 88.0
If we take 384 away from 395, we end up with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 48

On to step 5:
If we divide 111 by 48, we get 2 and a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 882.0
If we subtract 96 from 111, we get 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 48

Let's proceed to step 6:
157 divided by 48 is 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 8823.0
Subtracting 144 from 157 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
130 divided by 48 is 2 with a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 8823.2
The remainder is 34 after subtracting 96 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
340 divided by 48 is 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 8823.27
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
48 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 8823.27
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
When dividing 400 by 48, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 8823.2708
The remainder is 16 after subtracting 384 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
160 divided by 48 is 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 8823.27083
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
48 goes into 160 3 times with a remainder of 16.
The next digit of our result is 3. 
Result so far: 8823.270833
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 8823.270833, with a leftover of 1.6e-06.
