We look at the division of 287623 by 51 
We want to divide 287623 by 51.

Let's proceed to step 1:
When dividing 2 by 51, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 51

Advancing to step 2:
51 goes into 28 0 times with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 51

Advancing to step 3:
51 goes into 287 5 times with a remainder of 32.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 255 from 287 leaves us with 32.
Take the next digit (6) from the dividend and append it to 32, then repeat: 326 / 51

On to step 4:
51 can be fit into 326 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 56.0
Deduct 306 from 326 and we're left with 20.
Fetch the next digit (2) from the dividend, attach it to 20 and continue: 202 / 51

Going ahead to step 5:
51 can be fit into 202 3 times, resulting in a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 563.0
Subtracting 153 from 202 leaves us with 49.
Bring next digit (3) of the dividend behind the 49 and repeat the process: 493 / 51

Let's proceed to step 6:
The number 51 fits into 493 9 times, leaving a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 5639.0
Subtracting 459 from 493 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 7:
340 divided by 51 is 6 with a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 5639.6
The remainder is 34 after subtracting 306 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
When dividing 340 by 51, we get 6 with a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 5639.66
If we take 306 away from 340, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 5639.66, with a leftover of 0.034.
