We divide 686249 by 51
We're looking to find how many times 51 goes into 686249.

Let's proceed to step 1:
6 divided by 51 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 51

On to step 2:
The number 51 fits into 68 1 times, leaving a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 51 from 68, we get 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 51

Moving on to step 3:
176 divided by 51 is 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 153 from 176 to get 23.
Take the next digit (2) from the dividend and append it to 23, then repeat: 232 / 51

Moving on to step 4:
51 goes into 232 4 times with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
If we take 204 away from 232, we end up with 28.
Grab the next digit (4) from the dividend, add it to 28, then carry on: 284 / 51

Going ahead to step 5:
51 can be fit into 284 5 times, resulting in a remainder of 29.
The next digit of our result is 5. 
Result so far: 1345.0
If we subtract 255 from 284, we get 29.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 51

Advancing to step 6:
299 divided by 51 is 5 with a remainder of 44.
Use 5 as the next digit of our solution. 
Result so far: 13455.0
Subtract 255 from 299 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 7:
When dividing 440 by 51, we get 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 13455.8
If we subtract 408 from 440, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
If we divide 320 by 51, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 13455.86
The remainder is 14 after subtracting 306 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
51 goes into 140 2 times with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 13455.862
Deduct 102 from 140 and we're left 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 10:
51 can be fit into 380 7 times, resulting in a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 13455.8627
The remainder is 23 after subtracting 357 from 380.
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 11:
If we divide 230 by 51, we get 4 and a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 13455.86274
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.

Going ahead to step 12:
260 divided by 51 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 13455.862745
If we subtract 255 from 260, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
50 divided by 51 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 13455.862745
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.

On to step 14:
51 can be fit into 500 9 times, resulting in a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 13455.86274509
Subtract 459 from 500 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 result is 13455.86274509 with a remainder of 4.1e-08.
