48269871 ÷ 686 
We want to divide 48269871 by 686.

Going ahead to step 1:
686 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 686

Moving on to step 2:
686 goes into 48 0 times with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 48 to get 48.
Fetch the next digit (2) from the dividend, attach it to 48 and continue: 482 / 686

Step 3:
When dividing 482 by 686, we get 0 with a remainder of 482.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 482 to get 482.
Bring next digit (6) of the dividend behind the 482 and repeat the process: 4826 / 686

Let's proceed to step 4:
4826 divided by 686 is 7 with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 4802 from 4826 and we're left with 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 686

On to step 5:
686 goes into 249 0 times with a remainder of 249.
Put 0 as the next digit of the answer. 
Result so far: 70.0
If we take 0 away from 249, we end up with 249.
Fetch the next digit (8) from the dividend, attach it to 249 and continue: 2498 / 686

Let's proceed to step 6:
If we divide 2498 by 686, we get 3 and a remainder of 440.
Record the quotient 3 as the next digit in the result. 
Result so far: 703.0
Subtracting 2058 from 2498 leaves us with 440.
Fetch the next digit (7) from the dividend, attach it to 440 and continue: 4407 / 686

On to step 7:
The number 686 fits into 4407 6 times, leaving a remainder of 291.
Write down 6 as next digit of the result. 
Result so far: 7036.0
If we take 4116 away from 4407, we end up with 291.
Grab the next digit (1) from the dividend, add it to 291, then carry on: 2911 / 686

On to step 8:
If we divide 2911 by 686, we get 4 and a remainder of 167.
Use 4 as the next digit of our solution. 
Result so far: 70364.0
Subtract 2744 from 2911 to get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Advancing to step 9:
If we divide 1670 by 686, we get 2 and a remainder of 298.
The number 2 becomes the next digit in our result. 
Result so far: 70364.2
If we subtract 1372 from 1670, we get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 10:
686 goes into 2980 4 times with a remainder of 236.
The next digit of our result is 4. 
Result so far: 70364.24
Subtracting 2744 from 2980 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 11:
686 can be fit into 2360 3 times, resulting in a remainder of 302.
Use 3 as the next digit of our solution. 
Result so far: 70364.243
Subtract 2058 from 2360 to get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Let's proceed to step 12:
When dividing 3020 by 686, we get 4 with a remainder of 276.
Put 4 as the next digit of the answer. 
Result so far: 70364.2434
Subtract 2744 from 3020 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 13:
If we divide 2760 by 686, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 70364.24344
Subtracting 2744 from 2760 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 70364.24344 and a remainder of 1.6e-05.
