903123 divided by 10 
Our goal is to divide 903123 by 10.

Advancing to step 1:
9 divided by 10 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 10

Step 2:
If we divide 90 by 10, we get 9 and a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 90 away from 90, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 10

Let's proceed to step 3:
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: 90.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 10

Let's proceed to step 4:
When dividing 31 by 10, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 903.0
Subtracting 30 from 31 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 10

Advancing to step 5:
12 divided by 10 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 9031.0
Subtracting 10 from 12 leaves us with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 10

On to step 6:
When dividing 23 by 10, we get 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 90312.0
Deduct 20 from 23 and we're left 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.

Moving on to step 7:
The number 10 fits into 30 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 90312.3
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:
The number 10 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 90312.3
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.

Moving on to step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 90312.3
Deduct 0 from 0 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.

After the division, we end up with 90312.3 and a remainder of 0.0.
