We're dividing 157900 by 48 
The aim is to understand the frequency of 48 in 157900.

On to step 1:
The number 48 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 48

Going ahead to step 2:
48 goes into 15 0 times with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 48

Let's proceed to step 3:
When dividing 157 by 48, we get 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 144 from 157 to get 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 48

Moving on to step 4:
The number 48 fits into 139 2 times, leaving a remainder of 43.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we take 96 away from 139, we end up with 43.
Fetch the next digit (0) from the dividend, attach it to 43 and continue: 430 / 48

Moving on to step 5:
If we divide 430 by 48, we get 8 and a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 328.0
If we subtract 384 from 430, we get 46.
Bring next digit (0) of the dividend behind the 46 and repeat the process: 460 / 48

Step 6:
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: 3289.0
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.

Moving on to step 7:
If we divide 280 by 48, we get 5 and a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 3289.5
If we subtract 240 from 280, we get 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 8:
48 goes into 400 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 3289.58
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 9:
If we divide 160 by 48, we get 3 and a remainder of 16.
The next digit of our result is 3. 
Result so far: 3289.583
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 10:
When dividing 160 by 48, we get 3 with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 3289.5833
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 3289.5833, with a leftover of 0.00016.
