We're dividing 172735 by 48 
We want to figure out the number of times 172735 can be divided by 48.

Let's proceed to step 1:
When dividing 1 by 48, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 48

Step 2:
If we divide 17 by 48, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 48

Let's proceed to step 3:
The number 48 fits into 172 3 times, leaving a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 144 from 172 to get 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 48

Moving on to step 4:
When dividing 287 by 48, we get 5 with a remainder of 47.
The next digit of our result is 5. 
Result so far: 35.0
Subtract 240 from 287 to get 47.
Take the next digit (3) from the dividend and append it to 47, then repeat: 473 / 48

Going ahead to step 5:
48 goes into 473 9 times with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 359.0
If we take 432 away from 473, we end up with 41.
Fetch the next digit (5) from the dividend, attach it to 41 and continue: 415 / 48

Let's proceed to step 6:
If we divide 415 by 48, we get 8 and a remainder of 31.
Write down 8 as next digit of the result. 
Result so far: 3598.0
The remainder is 31 after subtracting 384 from 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
When dividing 310 by 48, we get 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 3598.6
If we subtract 288 from 310, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
When dividing 220 by 48, we get 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 3598.64
If we take 192 away from 220, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
48 goes into 280 5 times with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 3598.645
Deduct 240 from 280 and we're left 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.

Moving on to step 10:
48 can be fit into 400 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3598.6458
If we take 384 away from 400, 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.

Going ahead to step 11:
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: 3598.64583
Subtract 144 from 160 to 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.

Moving on to step 12:
If we divide 160 by 48, we get 3 and a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 3598.645833
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 3598.645833, with a leftover of 1.6e-06.
