51987631 divided by 287 
Our goal is to divide 51987631 by 287.

Let's proceed to step 1:
If we divide 5 by 287, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 287

On to step 2:
287 goes into 51 0 times with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 287

Step 3:
519 divided by 287 is 1 with a remainder of 232.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 287 from 519 to get 232.
Take the next digit (8) from the dividend and append it to 232, then repeat: 2328 / 287

Let's proceed to step 4:
When dividing 2328 by 287, we get 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 2296 from 2328 leaves us with 32.
Append the next digit (7) from the dividend to 32 and continue with: 327 / 287

Step 5:
287 goes into 327 1 times with a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 181.0
The remainder is 40 after subtracting 287 from 327.
Include the next digit (6) from the dividend after 40, then repeat: 406 / 287

On to step 6:
287 can be fit into 406 1 times, resulting in a remainder of 119.
Write down 1 as next digit of the result. 
Result so far: 1811.0
Deduct 287 from 406 and we're left with 119.
Include the next digit (3) from the dividend after 119, then repeat: 1193 / 287

Let's proceed to step 7:
1193 divided by 287 is 4 with a remainder of 45.
Record the quotient 4 as the next digit in the result. 
Result so far: 18114.0
Subtracting 1148 from 1193 leaves us with 45.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 287

Let's proceed to step 8:
287 can be fit into 451 1 times, resulting in a remainder of 164.
Write down 1 as next digit of the result. 
Result so far: 181141.0
If we take 287 away from 451, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 9:
1640 divided by 287 is 5 with a remainder of 205.
Write down 5 as next digit of the result. 
Result so far: 181141.5
Deduct 1435 from 1640 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 10:
When dividing 2050 by 287, we get 7 with a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 181141.57
If we take 2009 away from 2050, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 11:
When dividing 410 by 287, we get 1 with a remainder of 123.
The number 1 becomes the next digit in our result. 
Result so far: 181141.571
If we take 287 away from 410, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 12:
The number 287 fits into 1230 4 times, leaving a remainder of 82.
The number 4 becomes the next digit in our result. 
Result so far: 181141.5714
Subtracting 1148 from 1230 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 13:
287 can be fit into 820 2 times, resulting in a remainder of 246.
Record the quotient 2 as the next digit in the result. 
Result so far: 181141.57142
Deduct 574 from 820 and we're left with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 14:
The number 287 fits into 2460 8 times, leaving a remainder of 164.
The number 8 becomes the next digit in our result. 
Result so far: 181141.571428
If we take 2296 away from 2460, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 15:
When dividing 1640 by 287, we get 5 with a remainder of 205.
Use 5 as the next digit of our solution. 
Result so far: 181141.5714285
Deduct 1435 from 1640 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 16:
287 goes into 2050 7 times with a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 181141.57142857
Subtract 2009 from 2050 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final outcome is 181141.57142857, with a leftover of 4.1e-08.
