24780042 ÷ 123 
Let's see how many times 123 fits into 24780042.

Let's proceed to step 1:
If we divide 2 by 123, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 123

Let's proceed to step 2:
123 can be fit into 24 0 times, resulting in a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 24, we get 24.
Grab the next digit (7) from the dividend, add it to 24, then carry on: 247 / 123

Step 3:
If we divide 247 by 123, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 1 after subtracting 246 from 247.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 123

Advancing to step 4:
123 goes into 18 0 times with a remainder of 18.
The next digit of our result is 0. 
Result so far: 20.0
Deduct 0 from 18 and we're left with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 123

Going ahead to step 5:
180 divided by 123 is 1 with a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 201.0
If we subtract 123 from 180, we get 57.
Grab the next digit (0) from the dividend, add it to 57, then carry on: 570 / 123

Step 6:
123 goes into 570 4 times with a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 2014.0
Subtract 492 from 570 to get 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 123

Advancing to step 7:
When dividing 784 by 123, we get 6 with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 20146.0
Subtracting 738 from 784 leaves us with 46.
Grab the next digit (2) from the dividend, add it to 46, then carry on: 462 / 123

Step 8:
123 goes into 462 3 times with a remainder of 93.
Write down 3 as next digit of the result. 
Result so far: 201463.0
Deduct 369 from 462 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 9:
930 divided by 123 is 7 with a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 201463.7
Subtract 861 from 930 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 10:
123 goes into 690 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 201463.75
If we subtract 615 from 690, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 11:
If we divide 750 by 123, we get 6 and a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 201463.756
Subtracting 738 from 750 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.

Step 12:
123 goes into 120 0 times with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 201463.756
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 13:
123 can be fit into 1200 9 times, resulting in a remainder of 93.
Use 9 as the next digit of our solution. 
Result so far: 201463.75609
Deduct 1107 from 1200 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 14:
123 can be fit into 930 7 times, resulting in a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 201463.756097
The remainder is 69 after subtracting 861 from 930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 15:
The number 123 fits into 690 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 201463.7560975
Subtract 615 from 690 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 16:
When dividing 750 by 123, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 201463.75609756
If we subtract 738 from 750, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 201463.75609756 and a remainder of 1.2e-08.
