We're dividing 53687393 by 403 
We're looking to find how many times 403 goes into 53687393.

Advancing to step 1:
403 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 403

Advancing to step 2:
The number 403 fits into 53 0 times, leaving a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Append the next digit (6) from the dividend to 53 and continue with: 536 / 403

Advancing to step 3:
403 can be fit into 536 1 times, resulting in a remainder of 133.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 403 from 536 leaves us with 133.
Append the next digit (8) from the dividend to 133 and continue with: 1338 / 403

Going ahead to step 4:
403 can be fit into 1338 3 times, resulting in a remainder of 129.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 1209 from 1338 leaves us with 129.
Fetch the next digit (7) from the dividend, attach it to 129 and continue: 1297 / 403

Step 5:
1297 divided by 403 is 3 with a remainder of 88.
Put 3 as the next digit of the answer. 
Result so far: 133.0
Deduct 1209 from 1297 and we're left with 88.
Include the next digit (3) from the dividend after 88, then repeat: 883 / 403

Step 6:
The number 403 fits into 883 2 times, leaving a remainder of 77.
The next digit of our result is 2. 
Result so far: 1332.0
Subtract 806 from 883 to get 77.
Take the next digit (9) from the dividend and append it to 77, then repeat: 779 / 403

On to step 7:
403 can be fit into 779 1 times, resulting in a remainder of 376.
Record the quotient 1 as the next digit in the result. 
Result so far: 13321.0
If we subtract 403 from 779, we get 376.
Take the next digit (3) from the dividend and append it to 376, then repeat: 3763 / 403

Going ahead to step 8:
If we divide 3763 by 403, we get 9 and a remainder of 136.
The next digit of our result is 9. 
Result so far: 133219.0
The remainder is 136 after subtracting 3627 from 3763.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 9:
When dividing 1360 by 403, we get 3 with a remainder of 151.
Write down 3 as next digit of the result. 
Result so far: 133219.3
The remainder is 151 after subtracting 1209 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Going ahead to step 10:
The number 403 fits into 1510 3 times, leaving a remainder of 301.
The next digit of our result is 3. 
Result so far: 133219.33
If we subtract 1209 from 1510, we get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

In conclusion, the division gives 133219.33 with a balance of 0.301.
