We divide 53318230 by 403
Our goal is to divide 53318230 by 403.

Step 1:
If we divide 5 by 403, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 403

Moving on to step 2:
When dividing 53 by 403, we get 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Bring next digit (3) of the dividend behind the 53 and repeat the process: 533 / 403

On to step 3:
403 can be fit into 533 1 times, resulting in a remainder of 130.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 403 from 533, we get 130.
Take the next digit (1) from the dividend and append it to 130, then repeat: 1301 / 403

Step 4:
1301 divided by 403 is 3 with a remainder of 92.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 1209 from 1301 leaves us with 92.
Grab the next digit (8) from the dividend, add it to 92, then carry on: 928 / 403

Step 5:
403 goes into 928 2 times with a remainder of 122.
The number 2 becomes the next digit in our result. 
Result so far: 132.0
Subtract 806 from 928 to get 122.
Fetch the next digit (2) from the dividend, attach it to 122 and continue: 1222 / 403

Step 6:
403 can be fit into 1222 3 times, resulting in a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 1323.0
Deduct 1209 from 1222 and we're left with 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 403

Let's proceed to step 7:
133 divided by 403 is 0 with a remainder of 133.
Use 0 as the next digit of our solution. 
Result so far: 13230.0
Subtract 0 from 133 to get 133.
Take the next digit (0) from the dividend and append it to 133, then repeat: 1330 / 403

On to step 8:
The number 403 fits into 1330 3 times, leaving a remainder of 121.
Use 3 as the next digit of our solution. 
Result so far: 132303.0
If we subtract 1209 from 1330, we get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Let's proceed to step 9:
403 goes into 1210 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 132303.3
The remainder is 1 after subtracting 1209 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
403 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 132303.3
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
403 can be fit into 100 0 times, resulting in a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 132303.3
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 132303.3, with a leftover of 0.01.
