413971 divided by 48 
The aim is to understand the frequency of 48 in 413971.

Moving on 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
Subtracting 0 from 4 leaves us with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 48

Moving on to step 2:
41 divided by 48 is 0 with a remainder of 41.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Bring next digit (3) of the dividend behind the 41 and repeat the process: 413 / 48

Advancing to step 3:
The number 48 fits into 413 8 times, leaving a remainder of 29.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 384 from 413 and we're left with 29.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 48

Let's proceed to step 4:
299 divided by 48 is 6 with a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 86.0
Deduct 288 from 299 and we're left with 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 48

On to step 5:
117 divided by 48 is 2 with a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 862.0
If we take 96 away from 117, we end up with 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 48

Going ahead to step 6:
The number 48 fits into 211 4 times, leaving a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 8624.0
Subtracting 192 from 211 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
48 goes into 190 3 times with a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 8624.3
The remainder is 46 after subtracting 144 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 8:
The number 48 fits into 460 9 times, leaving a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 8624.39
If we subtract 432 from 460, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
48 goes into 280 5 times with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 8624.395
If we take 240 away from 280, we end up 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.

Advancing to step 10:
When dividing 400 by 48, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 8624.3958
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.

Step 11:
The number 48 fits into 160 3 times, leaving a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 8624.39583
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
The number 48 fits into 160 3 times, leaving a remainder of 16.
The next digit of our result is 3. 
Result so far: 8624.395833
If we take 144 away from 160, we end up 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 8624.395833, with a leftover of 1.6e-06.
