Let's divide 51431462 by 686
We want to figure out the number of times 51431462 can be divided by 686.

Step 1:
686 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 686

Advancing to step 2:
686 goes into 51 0 times with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Take the next digit (4) from the dividend and append it to 51, then repeat: 514 / 686

Going ahead to step 3:
When dividing 514 by 686, we get 0 with a remainder of 514.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 514 leaves us with 514.
Grab the next digit (3) from the dividend, add it to 514, then carry on: 5143 / 686

Going ahead to step 4:
686 goes into 5143 7 times with a remainder of 341.
The next digit of our result is 7. 
Result so far: 7.0
If we take 4802 away from 5143, we end up with 341.
Append the next digit (1) from the dividend to 341 and continue with: 3411 / 686

Moving on to step 5:
686 goes into 3411 4 times with a remainder of 667.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
If we take 2744 away from 3411, we end up with 667.
Take the next digit (4) from the dividend and append it to 667, then repeat: 6674 / 686

Advancing to step 6:
The number 686 fits into 6674 9 times, leaving a remainder of 500.
Put 9 as the next digit of the answer. 
Result so far: 749.0
Deduct 6174 from 6674 and we're left with 500.
Bring next digit (6) of the dividend behind the 500 and repeat the process: 5006 / 686

Going ahead to step 7:
When dividing 5006 by 686, we get 7 with a remainder of 204.
Write down 7 as next digit of the result. 
Result so far: 7497.0
Subtracting 4802 from 5006 leaves us with 204.
Fetch the next digit (2) from the dividend, attach it to 204 and continue: 2042 / 686

On to step 8:
686 goes into 2042 2 times with a remainder of 670.
The next digit of our result is 2. 
Result so far: 74972.0
If we take 1372 away from 2042, we end up with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Step 9:
6700 divided by 686 is 9 with a remainder of 526.
Record the quotient 9 as the next digit in the result. 
Result so far: 74972.9
If we subtract 6174 from 6700, we get 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Step 10:
686 goes into 5260 7 times with a remainder of 458.
Put 7 as the next digit of the answer. 
Result so far: 74972.97
Subtracting 4802 from 5260 leaves us with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Let's proceed to step 11:
If we divide 4580 by 686, we get 6 and a remainder of 464.
Write down 6 as next digit of the result. 
Result so far: 74972.976
Deduct 4116 from 4580 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Going ahead to step 12:
686 can be fit into 4640 6 times, resulting in a remainder of 524.
The next digit of our result is 6. 
Result so far: 74972.9766
The remainder is 524 after subtracting 4116 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

In conclusion, the division gives 74972.9766 with a balance of 0.00524.
