Let's divide 54235200 by 403
We're looking to find how many times 403 goes into 54235200.

Step 1:
403 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 403

Going ahead to step 2:
403 can be fit into 54 0 times, resulting in a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Bring next digit (2) of the dividend behind the 54 and repeat the process: 542 / 403

On to step 3:
When dividing 542 by 403, we get 1 with a remainder of 139.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 139 after subtracting 403 from 542.
Bring next digit (3) of the dividend behind the 139 and repeat the process: 1393 / 403

Advancing to step 4:
403 can be fit into 1393 3 times, resulting in a remainder of 184.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 1209 from 1393 and we're left with 184.
Include the next digit (5) from the dividend after 184, then repeat: 1845 / 403

Step 5:
When dividing 1845 by 403, we get 4 with a remainder of 233.
The next digit of our result is 4. 
Result so far: 134.0
Deduct 1612 from 1845 and we're left with 233.
Include the next digit (2) from the dividend after 233, then repeat: 2332 / 403

On to step 6:
2332 divided by 403 is 5 with a remainder of 317.
The number 5 becomes the next digit in our result. 
Result so far: 1345.0
If we take 2015 away from 2332, we end up with 317.
Bring next digit (0) of the dividend behind the 317 and repeat the process: 3170 / 403

Let's proceed to step 7:
When dividing 3170 by 403, we get 7 with a remainder of 349.
The next digit of our result is 7. 
Result so far: 13457.0
The remainder is 349 after subtracting 2821 from 3170.
Take the next digit (0) from the dividend and append it to 349, then repeat: 3490 / 403

Let's proceed to step 8:
When dividing 3490 by 403, we get 8 with a remainder of 266.
Put 8 as the next digit of the answer. 
Result so far: 134578.0
Subtract 3224 from 3490 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

On to step 9:
403 can be fit into 2660 6 times, resulting in a remainder of 242.
The number 6 becomes the next digit in our result. 
Result so far: 134578.6
If we take 2418 away from 2660, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 10:
403 goes into 2420 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 134578.66
If we take 2418 away from 2420, we end up 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.

The final result is 134578.66 with a remainder of 0.002.
