We look at the division of 29830489 by 123 
Our goal is to divide 29830489 by 123.

On to step 1:
The number 123 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 123

Moving on to step 2:
The number 123 fits into 29 0 times, leaving a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 123

Going ahead to step 3:
If we divide 298 by 123, we get 2 and a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 246 from 298 and we're left with 52.
Fetch the next digit (3) from the dividend, attach it to 52 and continue: 523 / 123

Advancing to step 4:
If we divide 523 by 123, we get 4 and a remainder of 31.
The next digit of our result is 4. 
Result so far: 24.0
Subtract 492 from 523 to get 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 123

Let's proceed to step 5:
123 goes into 310 2 times with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 242.0
Subtracting 246 from 310 leaves us with 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 123

Going ahead to step 6:
The number 123 fits into 644 5 times, leaving a remainder of 29.
Write down 5 as next digit of the result. 
Result so far: 2425.0
If we take 615 away from 644, we end up with 29.
Grab the next digit (8) from the dividend, add it to 29, then carry on: 298 / 123

On to step 7:
123 goes into 298 2 times with a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 24252.0
If we subtract 246 from 298, we get 52.
Fetch the next digit (9) from the dividend, attach it to 52 and continue: 529 / 123

On to step 8:
123 goes into 529 4 times with a remainder of 37.
Use 4 as the next digit of our solution. 
Result so far: 242524.0
Subtracting 492 from 529 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 9:
123 can be fit into 370 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 242524.3
Deduct 369 from 370 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 10:
123 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 242524.3
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
When dividing 100 by 123, we get 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 242524.3
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 242524.3 and a remainder of 0.01.
