We're dividing 51125506 by 303 
We want to divide 51125506 by 303.

Step 1:
If we divide 5 by 303, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 303

Let's proceed to step 2:
303 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Take the next digit (1) from the dividend and append it to 51, then repeat: 511 / 303

Advancing to step 3:
The number 303 fits into 511 1 times, leaving a remainder of 208.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 303 away from 511, we end up with 208.
Bring next digit (2) of the dividend behind the 208 and repeat the process: 2082 / 303

Step 4:
2082 divided by 303 is 6 with a remainder of 264.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 264 after subtracting 1818 from 2082.
Fetch the next digit (5) from the dividend, attach it to 264 and continue: 2645 / 303

Moving on to step 5:
The number 303 fits into 2645 8 times, leaving a remainder of 221.
Record the quotient 8 as the next digit in the result. 
Result so far: 168.0
If we take 2424 away from 2645, we end up with 221.
Bring next digit (5) of the dividend behind the 221 and repeat the process: 2215 / 303

Moving on to step 6:
When dividing 2215 by 303, we get 7 with a remainder of 94.
Use 7 as the next digit of our solution. 
Result so far: 1687.0
If we take 2121 away from 2215, we end up with 94.
Fetch the next digit (0) from the dividend, attach it to 94 and continue: 940 / 303

Advancing to step 7:
The number 303 fits into 940 3 times, leaving a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 16873.0
Subtracting 909 from 940 leaves us with 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 303

Advancing to step 8:
When dividing 316 by 303, we get 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 168731.0
Subtract 303 from 316 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
130 divided by 303 is 0 with a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 168731.0
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 10:
303 can be fit into 1300 4 times, resulting in a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 168731.04
Subtracting 1212 from 1300 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 11:
303 goes into 880 2 times with a remainder of 274.
Put 2 as the next digit of the answer. 
Result so far: 168731.042
Subtract 606 from 880 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 12:
303 goes into 2740 9 times with a remainder of 13.
The next digit of our result is 9. 
Result so far: 168731.0429
If we take 2727 away from 2740, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 13:
130 divided by 303 is 0 with a remainder of 130.
Record the quotient 0 as the next digit in the result. 
Result so far: 168731.0429
If we take 0 away from 130, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 14:
When dividing 1300 by 303, we get 4 with a remainder of 88.
Record the quotient 4 as the next digit in the result. 
Result so far: 168731.042904
Subtract 1212 from 1300 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 15:
303 can be fit into 880 2 times, resulting in a remainder of 274.
Write down 2 as next digit of the result. 
Result so far: 168731.0429042
Subtract 606 from 880 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 16:
If we divide 2740 by 303, we get 9 and a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 168731.04290429
If we take 2727 away from 2740, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 168731.04290429, with a leftover of 1.3e-08.
