40438634 divided by 403 
We're looking to find how many times 403 goes into 40438634.

On to step 1:
4 divided by 403 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 403

Going ahead to step 2:
When dividing 40 by 403, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Take the next digit (4) from the dividend and append it to 40, then repeat: 404 / 403

On to step 3:
The number 403 fits into 404 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 403 from 404 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 403

On to step 4:
403 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 13, we end up with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 403

On to step 5:
When dividing 138 by 403, we get 0 with a remainder of 138.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
The remainder is 138 after subtracting 0 from 138.
Fetch the next digit (6) from the dividend, attach it to 138 and continue: 1386 / 403

Step 6:
1386 divided by 403 is 3 with a remainder of 177.
Use 3 as the next digit of our solution. 
Result so far: 1003.0
The remainder is 177 after subtracting 1209 from 1386.
Bring next digit (3) of the dividend behind the 177 and repeat the process: 1773 / 403

Moving on to step 7:
403 can be fit into 1773 4 times, resulting in a remainder of 161.
The next digit of our result is 4. 
Result so far: 10034.0
If we subtract 1612 from 1773, we get 161.
Bring next digit (4) of the dividend behind the 161 and repeat the process: 1614 / 403

Advancing to step 8:
When dividing 1614 by 403, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 100344.0
Subtracting 1612 from 1614 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
The number 403 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 100344.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
The number 403 fits into 200 0 times, leaving a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 100344.0
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 100344.0 with a balance of 0.2.
