We're dividing 172659 by 48 
We want to divide 172659 by 48.

Let's proceed to step 1:
48 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 48

Advancing to step 2:
The number 48 fits into 17 0 times, leaving a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 48

Let's proceed to step 3:
48 goes into 172 3 times with a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 144 from 172 to get 28.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 48

Let's proceed to step 4:
48 can be fit into 286 5 times, resulting in a remainder of 46.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Subtracting 240 from 286 leaves us with 46.
Bring next digit (5) of the dividend behind the 46 and repeat the process: 465 / 48

Going ahead to step 5:
When dividing 465 by 48, we get 9 with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 359.0
Subtract 432 from 465 to get 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 48

On to step 6:
The number 48 fits into 339 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 3597.0
Deduct 336 from 339 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
48 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 3597.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
300 divided by 48 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 3597.06
Subtracting 288 from 300 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
48 can be fit into 120 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 3597.062
Subtracting 96 from 120 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
240 divided by 48 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 3597.0625
The remainder is 0 after subtracting 240 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
When dividing 0 by 48, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3597.0625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
The number 48 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3597.0625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 3597.0625, with a leftover of 0.0.
