We look at the division of 138803 by 10 
We want to figure out the number of times 138803 can be divided by 10.

Step 1:
10 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 10

Let's proceed to step 2:
10 can be fit into 13 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 10 away from 13, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 10

Advancing to step 3:
10 can be fit into 38 3 times, resulting in a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 30 away from 38, we end up with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 10

Step 4:
If we divide 88 by 10, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 138.0
If we take 80 away from 88, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 10

Step 5:
If we divide 80 by 10, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 1388.0
Subtracting 80 from 80 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 10

Step 6:
The number 10 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 13880.0
Subtracting 0 from 3 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
10 goes into 30 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 13880.3
If we take 30 away from 30, 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.

Going ahead to step 8:
0 divided by 10 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13880.3
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.

Going ahead to step 9:
10 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13880.3
The remainder is 0 after subtracting 0 from 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 result is 13880.3 with a remainder of 0.0.
