We're dividing 50186830 by 403 
We want to divide 50186830 by 403.

Advancing to step 1:
403 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 403

Moving on to step 2:
If we divide 50 by 403, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Include the next digit (1) from the dividend after 50, then repeat: 501 / 403

Moving on to step 3:
501 divided by 403 is 1 with a remainder of 98.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 98 after subtracting 403 from 501.
Append the next digit (8) from the dividend to 98 and continue with: 988 / 403

On to step 4:
403 goes into 988 2 times with a remainder of 182.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 806 from 988, we get 182.
Fetch the next digit (6) from the dividend, attach it to 182 and continue: 1826 / 403

Advancing to step 5:
403 can be fit into 1826 4 times, resulting in a remainder of 214.
The next digit of our result is 4. 
Result so far: 124.0
If we take 1612 away from 1826, we end up with 214.
Grab the next digit (8) from the dividend, add it to 214, then carry on: 2148 / 403

Going ahead to step 6:
403 can be fit into 2148 5 times, resulting in a remainder of 133.
Put 5 as the next digit of the answer. 
Result so far: 1245.0
If we subtract 2015 from 2148, we get 133.
Grab the next digit (3) from the dividend, add it to 133, then carry on: 1333 / 403

On to step 7:
The number 403 fits into 1333 3 times, leaving a remainder of 124.
The number 3 becomes the next digit in our result. 
Result so far: 12453.0
Subtracting 1209 from 1333 leaves us with 124.
Bring next digit (0) of the dividend behind the 124 and repeat the process: 1240 / 403

Step 8:
If we divide 1240 by 403, we get 3 and a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 124533.0
The remainder is 31 after subtracting 1209 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
The number 403 fits into 310 0 times, leaving a remainder of 310.
The number 0 becomes the next digit in our result. 
Result so far: 124533.0
Subtracting 0 from 310 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 10:
3100 divided by 403 is 7 with a remainder of 279.
The next digit of our result is 7. 
Result so far: 124533.07
The remainder is 279 after subtracting 2821 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

On to step 11:
The number 403 fits into 2790 6 times, leaving a remainder of 372.
The next digit of our result is 6. 
Result so far: 124533.076
If we take 2418 away from 2790, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 12:
3720 divided by 403 is 9 with a remainder of 93.
Write down 9 as next digit of the result. 
Result so far: 124533.0769
Subtract 3627 from 3720 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Let's proceed to step 13:
When dividing 930 by 403, we get 2 with a remainder of 124.
The number 2 becomes the next digit in our result. 
Result so far: 124533.07692
If we subtract 806 from 930, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 14:
If we divide 1240 by 403, we get 3 and a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 124533.076923
Deduct 1209 from 1240 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 15:
310 divided by 403 is 0 with a remainder of 310.
Record the quotient 0 as the next digit in the result. 
Result so far: 124533.076923
Subtracting 0 from 310 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 16:
403 goes into 3100 7 times with a remainder of 279.
Write down 7 as next digit of the result. 
Result so far: 124533.07692307
Subtract 2821 from 3100 to get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

The final outcome is 124533.07692307, with a leftover of 2.79e-07.
