We divide 172830 by 55
We want to divide 172830 by 55.

Going ahead to step 1:
The number 55 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 55

Step 2:
The number 55 fits into 17 0 times, leaving a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 55

Let's proceed to step 3:
If we divide 172 by 55, we get 3 and a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 165 from 172 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 55

On to step 4:
55 goes into 78 1 times with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we take 55 away from 78, we end up with 23.
Grab the next digit (3) from the dividend, add it to 23, then carry on: 233 / 55

On to step 5:
The number 55 fits into 233 4 times, leaving a remainder of 13.
The next digit of our result is 4. 
Result so far: 314.0
If we take 220 away from 233, we end up with 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 55

Step 6:
If we divide 130 by 55, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 3142.0
Deduct 110 from 130 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
55 can be fit into 200 3 times, resulting in a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 3142.3
The remainder is 35 after subtracting 165 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 8:
When dividing 350 by 55, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 3142.36
If we subtract 330 from 350, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
55 goes into 200 3 times with a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 3142.363
If we take 165 away from 200, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 10:
55 can be fit into 350 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 3142.3636
If we subtract 330 from 350, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
If we divide 200 by 55, we get 3 and a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 3142.36363
If we take 165 away from 200, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
When dividing 350 by 55, we get 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 3142.363636
If we subtract 330 from 350, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
When dividing 200 by 55, we get 3 with a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 3142.3636363
Subtract 165 from 200 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 14:
350 divided by 55 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 3142.36363636
Subtracting 330 from 350 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 3142.36363636, with a leftover of 2e-08.
