We're dividing 703890 by 10 
We want to divide 703890 by 10.

Advancing to step 1:
When dividing 7 by 10, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 10

Going ahead to step 2:
The number 10 fits into 70 7 times, leaving a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 70 from 70 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 10

Going ahead to step 3:
When dividing 3 by 10, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 70.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 10

Advancing to step 4:
38 divided by 10 is 3 with a remainder of 8.
The next digit of our result is 3. 
Result so far: 703.0
Subtracting 30 from 38 leaves us with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 10

On to step 5:
When dividing 89 by 10, we get 8 with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 7038.0
If we take 80 away from 89, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 10

Going ahead to step 6:
When dividing 90 by 10, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 70389.0
The remainder is 0 after subtracting 90 from 90.
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:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 70389.0
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:
When dividing 0 by 10, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 70389.0
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 70389.0 with a remainder of 0.0.
