We divide 403010 by 4
We want to figure out the number of times 403010 can be divided by 4.

Advancing to step 1:
The number 4 fits into 4 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 4 from 4 leaves us with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 4

Let's proceed to step 2:
0 divided by 4 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 0 after subtracting 0 from 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 4

On to step 3:
If we divide 3 by 4, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 100.0
If we subtract 0 from 3, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 4

Going ahead to step 4:
The number 4 fits into 30 7 times, leaving a remainder of 2.
The next digit of our result is 7. 
Result so far: 1007.0
The remainder is 2 after subtracting 28 from 30.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 4

On to step 5:
When dividing 21 by 4, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 10075.0
Subtract 20 from 21 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 4

Going ahead to step 6:
If we divide 10 by 4, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 100752.0
Subtract 8 from 10 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
4 can be fit into 20 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 100752.5
If we take 20 away from 20, 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:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 100752.5
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 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 100752.5
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 outcome is 100752.5, with a leftover of 0.0.
