Moving on to step 3:
180 divided by 123 is 1 with a remainder of 57.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 57 after subtracting 123 from 180.
Include the next digit (2) from the dividend after 57, then repeat: 572 / 123

On to step 4:
When dividing 572 by 123, we get 4 with a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 492 from 572 leaves us with 80.
Bring next digit (6) of the dividend behind the 80 and repeat the process: 806 / 123

On to step 5:
123 can be fit into 806 6 times, resulting in a remainder of 68.
The next digit of our result is 6. 
Result so far: 146.0
The remainder is 68 after subtracting 738 from 806.
Append the next digit (3) from the dividend to 68 and continue with: 683 / 123

Advancing to step 6:
When dividing 683 by 123, we get 5 with a remainder of 68.
Record the quotient 5 as the next digit in the result. 
Result so far: 1465.0
Subtract 615 from 683 to get 68.
Grab the next digit (8) from the dividend, add it to 68, then carry on: 688 / 123

Going ahead to step 7:
688 divided by 123 is 5 with a remainder of 73.
Put 5 as the next digit of the answer. 
Result so far: 14655.0
If we subtract 615 from 688, we get 73.
Bring next digit (6) of the dividend behind the 73 and repeat the process: 736 / 123

Advancing to step 8:
When dividing 736 by 123, we get 5 with a remainder of 121.
Put 5 as the next digit of the answer. 
Result so far: 146555.0
If we subtract 615 from 736, we get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 9:
1210 divided by 123 is 9 with a remainder of 103.
Use 9 as the next digit of our solution. 
Result so far: 146555.9
Deduct 1107 from 1210 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 10:
When dividing 1030 by 123, we get 8 with a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 146555.98
The remainder is 46 after subtracting 984 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
123 can be fit into 460 3 times, resulting in a remainder of 91.
The next digit of our result is 3. 
Result so far: 146555.983
Subtract 369 from 460 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Let's proceed to step 12:
When dividing 910 by 123, we get 7 with a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 146555.9837
If we subtract 861 from 910, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 13:
When dividing 490 by 123, we get 3 with a remainder of 121.
The next digit of our result is 3. 
Result so far: 146555.98373
Subtracting 369 from 490 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 14:
When dividing 1210 by 123, we get 9 with a remainder of 103.
Write down 9 as next digit of the result. 
Result so far: 146555.983739
If we take 1107 away from 1210, we end up with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Going ahead to step 15:
1030 divided by 123 is 8 with a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 146555.9837398
The remainder is 46 after subtracting 984 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 16:
The number 123 fits into 460 3 times, leaving a remainder of 91.
Put 3 as the next digit of the answer. 
Result so far: 146555.98373983
Subtract 369 from 460 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

In conclusion, the division gives 146555.98373983 with a balance of 9.1e-08.
