We're dividing 51410279 by 143 
Let's see how many times 143 fits into 51410279.

On to step 1:
143 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 143

Going ahead to step 2:
143 can be fit into 51 0 times, resulting in a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Fetch the next digit (4) from the dividend, attach it to 51 and continue: 514 / 143

On to step 3:
When dividing 514 by 143, we get 3 with a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 429 from 514 leaves us with 85.
Bring next digit (1) of the dividend behind the 85 and repeat the process: 851 / 143

Going ahead to step 4:
If we divide 851 by 143, we get 5 and a remainder of 136.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we subtract 715 from 851, we get 136.
Include the next digit (0) from the dividend after 136, then repeat: 1360 / 143

Let's proceed to step 5:
If we divide 1360 by 143, we get 9 and a remainder of 73.
The next digit of our result is 9. 
Result so far: 359.0
Subtracting 1287 from 1360 leaves us with 73.
Append the next digit (2) from the dividend to 73 and continue with: 732 / 143

Moving on to step 6:
If we divide 732 by 143, we get 5 and a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 3595.0
If we subtract 715 from 732, we get 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 143

Step 7:
The number 143 fits into 177 1 times, leaving a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 35951.0
If we take 143 away from 177, we end up with 34.
Fetch the next digit (9) from the dividend, attach it to 34 and continue: 349 / 143

Going ahead to step 8:
The number 143 fits into 349 2 times, leaving a remainder of 63.
The next digit of our result is 2. 
Result so far: 359512.0
The remainder is 63 after subtracting 286 from 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 9:
143 can be fit into 630 4 times, resulting in a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 359512.4
If we take 572 away from 630, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 10:
143 can be fit into 580 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 359512.44
If we subtract 572 from 580, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 359512.44, with a leftover of 0.008.
