We divide 30203903 by 123
We want to divide 30203903 by 123.

On to step 1:
3 divided by 123 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 123

Advancing to step 2:
30 divided by 123 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 123

Moving on to step 3:
123 goes into 302 2 times with a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 246 from 302, we get 56.
Grab the next digit (0) from the dividend, add it to 56, then carry on: 560 / 123

Let's proceed to step 4:
When dividing 560 by 123, we get 4 with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we take 492 away from 560, we end up with 68.
Grab the next digit (3) from the dividend, add it to 68, then carry on: 683 / 123

Let's proceed to step 5:
123 goes into 683 5 times with a remainder of 68.
Record the quotient 5 as the next digit in the result. 
Result so far: 245.0
Subtract 615 from 683 to get 68.
Bring next digit (9) of the dividend behind the 68 and repeat the process: 689 / 123

Let's proceed to step 6:
When dividing 689 by 123, we get 5 with a remainder of 74.
The number 5 becomes the next digit in our result. 
Result so far: 2455.0
Subtracting 615 from 689 leaves us with 74.
Grab the next digit (0) from the dividend, add it to 74, then carry on: 740 / 123

Advancing to step 7:
123 can be fit into 740 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 24556.0
If we take 738 away from 740, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 123

Going ahead to step 8:
The number 123 fits into 23 0 times, leaving a remainder of 23.
The next digit of our result is 0. 
Result so far: 245560.0
The remainder is 23 after subtracting 0 from 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
123 goes into 230 1 times with a remainder of 107.
Record the quotient 1 as the next digit in the result. 
Result so far: 245560.1
If we take 123 away from 230, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Step 10:
123 goes into 1070 8 times with a remainder of 86.
Write down 8 as next digit of the result. 
Result so far: 245560.18
Subtracting 984 from 1070 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 11:
860 divided by 123 is 6 with a remainder of 122.
Record the quotient 6 as the next digit in the result. 
Result so far: 245560.186
If we take 738 away from 860, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 12:
123 can be fit into 1220 9 times, resulting in a remainder of 113.
Use 9 as the next digit of our solution. 
Result so far: 245560.1869
If we subtract 1107 from 1220, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Step 13:
123 can be fit into 1130 9 times, resulting in a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 245560.18699
Subtract 1107 from 1130 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The quotient of the division is 245560.18699, and the remainder is 2.3e-05.
