Let's divide 903879 by 9
We want to figure out the number of times 903879 can be divided by 9.

Step 1:
9 divided by 9 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 9 from 9 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 9

Moving on to step 2:
The number 9 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 0, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 9

Going ahead to step 3:
If we divide 3 by 9, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 9

On to step 4:
If we divide 38 by 9, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 1004.0
The remainder is 2 after subtracting 36 from 38.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 9

Going ahead to step 5:
When dividing 27 by 9, we get 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 10043.0
Subtracting 27 from 27 leaves us with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 9

Let's proceed to step 6:
If we divide 9 by 9, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 100431.0
Subtract 9 from 9 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 7:
When dividing 0 by 9, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 100431.0
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.

Going ahead to step 8:
If we divide 0 by 9, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 100431.0
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.

The final outcome is 100431.0, with a leftover of 0.0.
