We look at the division of 123994 by 10 
We're looking to find how many times 10 goes into 123994.

Advancing to step 1:
10 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 10

Moving on to step 2:
When dividing 12 by 10, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 2 after subtracting 10 from 12.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 10

Going ahead to step 3:
The number 10 fits into 23 2 times, leaving a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 20 from 23, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 10

Going ahead to step 4:
The number 10 fits into 39 3 times, leaving a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 123.0
The remainder is 9 after subtracting 30 from 39.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 10

Going ahead to step 5:
If we divide 99 by 10, we get 9 and a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 1239.0
If we take 90 away from 99, we end up with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 10

Step 6:
94 divided by 10 is 9 with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 12399.0
If we take 90 away from 94, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
40 divided by 10 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 12399.4
Deduct 40 from 40 and we're left 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.

Going ahead to step 8:
10 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12399.4
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.

Moving on to step 9:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12399.4
If we subtract 0 from 0, 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.

Our division results in 12399.4 with a remaining 0.0.
