We divide 47879839 by 686
We're looking to find how many times 686 goes into 47879839.

Step 1:
686 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 686

Going ahead to step 2:
686 goes into 47 0 times with a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 47 and we're left with 47.
Fetch the next digit (8) from the dividend, attach it to 47 and continue: 478 / 686

Going ahead to step 3:
The number 686 fits into 478 0 times, leaving a remainder of 478.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 478 and we're left with 478.
Bring next digit (7) of the dividend behind the 478 and repeat the process: 4787 / 686

On to step 4:
The number 686 fits into 4787 6 times, leaving a remainder of 671.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 671 after subtracting 4116 from 4787.
Fetch the next digit (9) from the dividend, attach it to 671 and continue: 6719 / 686

Moving on to step 5:
The number 686 fits into 6719 9 times, leaving a remainder of 545.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Subtract 6174 from 6719 to get 545.
Fetch the next digit (8) from the dividend, attach it to 545 and continue: 5458 / 686

Let's proceed to step 6:
When dividing 5458 by 686, we get 7 with a remainder of 656.
Record the quotient 7 as the next digit in the result. 
Result so far: 697.0
If we subtract 4802 from 5458, we get 656.
Grab the next digit (3) from the dividend, add it to 656, then carry on: 6563 / 686

Going ahead to step 7:
The number 686 fits into 6563 9 times, leaving a remainder of 389.
The next digit of our result is 9. 
Result so far: 6979.0
If we take 6174 away from 6563, we end up with 389.
Grab the next digit (9) from the dividend, add it to 389, then carry on: 3899 / 686

Moving on to step 8:
If we divide 3899 by 686, we get 5 and a remainder of 469.
Write down 5 as next digit of the result. 
Result so far: 69795.0
If we take 3430 away from 3899, we end up with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Step 9:
When dividing 4690 by 686, we get 6 with a remainder of 574.
Use 6 as the next digit of our solution. 
Result so far: 69795.6
If we take 4116 away from 4690, we end up with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Step 10:
686 goes into 5740 8 times with a remainder of 252.
Write down 8 as next digit of the result. 
Result so far: 69795.68
The remainder is 252 after subtracting 5488 from 5740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 11:
686 goes into 2520 3 times with a remainder of 462.
Record the quotient 3 as the next digit in the result. 
Result so far: 69795.683
If we take 2058 away from 2520, we end up with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Step 12:
The number 686 fits into 4620 6 times, leaving a remainder of 504.
The number 6 becomes the next digit in our result. 
Result so far: 69795.6836
If we subtract 4116 from 4620, we get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Step 13:
If we divide 5040 by 686, we get 7 and a remainder of 238.
Record the quotient 7 as the next digit in the result. 
Result so far: 69795.68367
Deduct 4802 from 5040 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 14:
When dividing 2380 by 686, we get 3 with a remainder of 322.
Record the quotient 3 as the next digit in the result. 
Result so far: 69795.683673
Subtract 2058 from 2380 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 15:
686 goes into 3220 4 times with a remainder of 476.
The next digit of our result is 4. 
Result so far: 69795.6836734
If we subtract 2744 from 3220, we get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 16:
686 can be fit into 4760 6 times, resulting in a remainder of 644.
Record the quotient 6 as the next digit in the result. 
Result so far: 69795.68367346
Subtracting 4116 from 4760 leaves us with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

The final result is 69795.68367346 with a remainder of 6.44e-07.
