We look at the division of 172672 by 48 
Our goal is to divide 172672 by 48.

Advancing to step 1:
48 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 48

Going ahead to step 2:
If we divide 17 by 48, we get 0 and a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 48

Going ahead to step 3:
When dividing 172 by 48, we get 3 with a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 28 after subtracting 144 from 172.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 48

On to step 4:
The number 48 fits into 286 5 times, leaving a remainder of 46.
The next digit of our result is 5. 
Result so far: 35.0
Subtracting 240 from 286 leaves us with 46.
Append the next digit (7) from the dividend to 46 and continue with: 467 / 48

Step 5:
48 can be fit into 467 9 times, resulting in a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 359.0
Subtract 432 from 467 to get 35.
Bring next digit (2) of the dividend behind the 35 and repeat the process: 352 / 48

Moving on to step 6:
The number 48 fits into 352 7 times, leaving a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 3597.0
Deduct 336 from 352 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.

Advancing to step 7:
When dividing 160 by 48, we get 3 with a remainder of 16.
The next digit of our result is 3. 
Result so far: 3597.3
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.

Let's proceed to step 8:
When dividing 160 by 48, we get 3 with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 3597.33
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 result is 3597.33 with a remainder of 0.016.
