172155 ÷ 60 
Our goal is to divide 172155 by 60.

On to step 1:
The number 60 fits into 1 0 times, leaving 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 / 60

Moving on to step 2:
The number 60 fits into 17 0 times, leaving a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 60

On to step 3:
60 can be fit into 172 2 times, resulting in a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 120 from 172 to get 52.
Take the next digit (1) from the dividend and append it to 52, then repeat: 521 / 60

On to step 4:
60 goes into 521 8 times with a remainder of 41.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we subtract 480 from 521, we get 41.
Bring next digit (5) of the dividend behind the 41 and repeat the process: 415 / 60

Moving on to step 5:
415 divided by 60 is 6 with a remainder of 55.
Use 6 as the next digit of our solution. 
Result so far: 286.0
Subtracting 360 from 415 leaves us with 55.
Bring next digit (5) of the dividend behind the 55 and repeat the process: 555 / 60

Let's proceed to step 6:
555 divided by 60 is 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 2869.0
The remainder is 15 after subtracting 540 from 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
60 can be fit into 150 2 times, resulting in a remainder of 30.
The next digit of our result is 2. 
Result so far: 2869.2
The remainder is 30 after subtracting 120 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
If we divide 300 by 60, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2869.25
Subtracting 300 from 300 leaves us 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.

Advancing to step 9:
60 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2869.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
60 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 2869.25
The remainder is 0 after subtracting 0 from 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 2869.25, with a leftover of 0.0.
