We look at the division of 123908 by 2 
We want to divide 123908 by 2.

Moving on to step 1:
2 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 2

Moving on to step 2:
If we divide 12 by 2, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 12 away from 12, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 2

Step 3:
If we divide 3 by 2, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
Deduct 2 from 3 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 2

On to step 4:
2 goes into 19 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 619.0
Subtract 18 from 19 to get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 2

Going ahead to step 5:
2 goes into 10 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 6195.0
Deduct 10 from 10 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 2

Advancing to step 6:
When dividing 8 by 2, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 61954.0
If we subtract 8 from 8, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 61954.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 61954.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 61954.0, with a leftover of 0.0.
