47151782 ÷ 686 
Let's see how many times 686 fits into 47151782.

Going ahead to step 1:
When dividing 4 by 686, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 686

Moving on to step 2:
686 goes into 47 0 times with a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 47, we end up with 47.
Take the next digit (1) from the dividend and append it to 47, then repeat: 471 / 686

Step 3:
471 divided by 686 is 0 with a remainder of 471.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 471, we get 471.
Grab the next digit (5) from the dividend, add it to 471, then carry on: 4715 / 686

On to step 4:
686 can be fit into 4715 6 times, resulting in a remainder of 599.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 4116 from 4715, we get 599.
Bring next digit (1) of the dividend behind the 599 and repeat the process: 5991 / 686

Advancing to step 5:
If we divide 5991 by 686, we get 8 and a remainder of 503.
Put 8 as the next digit of the answer. 
Result so far: 68.0
The remainder is 503 after subtracting 5488 from 5991.
Take the next digit (7) from the dividend and append it to 503, then repeat: 5037 / 686

Moving on to step 6:
686 goes into 5037 7 times with a remainder of 235.
Record the quotient 7 as the next digit in the result. 
Result so far: 687.0
If we subtract 4802 from 5037, we get 235.
Include the next digit (8) from the dividend after 235, then repeat: 2358 / 686

On to step 7:
The number 686 fits into 2358 3 times, leaving a remainder of 300.
The number 3 becomes the next digit in our result. 
Result so far: 6873.0
Subtracting 2058 from 2358 leaves us with 300.
Fetch the next digit (2) from the dividend, attach it to 300 and continue: 3002 / 686

Moving on to step 8:
If we divide 3002 by 686, we get 4 and a remainder of 258.
Write down 4 as next digit of the result. 
Result so far: 68734.0
If we subtract 2744 from 3002, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 9:
2580 divided by 686 is 3 with a remainder of 522.
The number 3 becomes the next digit in our result. 
Result so far: 68734.3
The remainder is 522 after subtracting 2058 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Step 10:
5220 divided by 686 is 7 with a remainder of 418.
The number 7 becomes the next digit in our result. 
Result so far: 68734.37
The remainder is 418 after subtracting 4802 from 5220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Step 11:
686 can be fit into 4180 6 times, resulting in a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 68734.376
Deduct 4116 from 4180 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
686 can be fit into 640 0 times, resulting in a remainder of 640.
Use 0 as the next digit of our solution. 
Result so far: 68734.376
Subtract 0 from 640 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 13:
When dividing 6400 by 686, we get 9 with a remainder of 226.
The number 9 becomes the next digit in our result. 
Result so far: 68734.37609
If we subtract 6174 from 6400, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 14:
If we divide 2260 by 686, we get 3 and a remainder of 202.
The next digit of our result is 3. 
Result so far: 68734.376093
Subtract 2058 from 2260 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 15:
686 can be fit into 2020 2 times, resulting in a remainder of 648.
Put 2 as the next digit of the answer. 
Result so far: 68734.3760932
Deduct 1372 from 2020 and we're left with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

On to step 16:
The number 686 fits into 6480 9 times, leaving a remainder of 306.
Record the quotient 9 as the next digit in the result. 
Result so far: 68734.37609329
Deduct 6174 from 6480 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

The final result is 68734.37609329 with a remainder of 3.06e-07.
