286124 divided by 51 
We want to figure out the number of times 286124 can be divided by 51.

Moving on 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

Going ahead to step 2:
When dividing 28 by 51, we get 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 51

On to step 3:
51 can be fit into 286 5 times, resulting in a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 255 from 286 leaves us with 31.
Append the next digit (1) from the dividend to 31 and continue with: 311 / 51

On to step 4:
51 can be fit into 311 6 times, resulting in a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
Deduct 306 from 311 and we're left with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 51

Step 5:
51 can be fit into 52 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 561.0
The remainder is 1 after subtracting 51 from 52.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 51

Step 6:
The number 51 fits into 14 0 times, leaving a remainder of 14.
The next digit of our result is 0. 
Result so far: 5610.0
Deduct 0 from 14 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
51 goes into 140 2 times with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 5610.2
Subtracting 102 from 140 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 8:
51 can be fit into 380 7 times, resulting in a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 5610.27
If we subtract 357 from 380, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 9:
When dividing 230 by 51, we get 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 5610.274
Subtract 204 from 230 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 10:
The number 51 fits into 260 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 5610.2745
Subtracting 255 from 260 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
51 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 5610.2745
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
If we divide 500 by 51, we get 9 and a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 5610.274509
The remainder is 41 after subtracting 459 from 500.
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 13:
If we divide 410 by 51, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 5610.2745098
Subtract 408 from 410 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 14:
20 divided by 51 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 5610.2745098
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 5610.2745098, with a leftover of 2e-08.
