43679408 divided by 686 
Let's see how many times 686 fits into 43679408.

Let's proceed to step 1:
If we divide 4 by 686, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 686

Step 2:
When dividing 43 by 686, we get 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (6) from the dividend, attach it to 43 and continue: 436 / 686

Step 3:
When dividing 436 by 686, we get 0 with a remainder of 436.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 436, we end up with 436.
Bring next digit (7) of the dividend behind the 436 and repeat the process: 4367 / 686

Moving on to step 4:
The number 686 fits into 4367 6 times, leaving a remainder of 251.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 4116 from 4367, we get 251.
Take the next digit (9) from the dividend and append it to 251, then repeat: 2519 / 686

On to step 5:
When dividing 2519 by 686, we get 3 with a remainder of 461.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Subtract 2058 from 2519 to get 461.
Append the next digit (4) from the dividend to 461 and continue with: 4614 / 686

Let's proceed to step 6:
4614 divided by 686 is 6 with a remainder of 498.
The next digit of our result is 6. 
Result so far: 636.0
If we subtract 4116 from 4614, we get 498.
Fetch the next digit (0) from the dividend, attach it to 498 and continue: 4980 / 686

Step 7:
When dividing 4980 by 686, we get 7 with a remainder of 178.
The number 7 becomes the next digit in our result. 
Result so far: 6367.0
The remainder is 178 after subtracting 4802 from 4980.
Append the next digit (8) from the dividend to 178 and continue with: 1788 / 686

Step 8:
686 can be fit into 1788 2 times, resulting in a remainder of 416.
Write down 2 as next digit of the result. 
Result so far: 63672.0
The remainder is 416 after subtracting 1372 from 1788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 9:
686 goes into 4160 6 times with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 63672.6
Subtracting 4116 from 4160 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
If we divide 440 by 686, we get 0 and a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 63672.6
If we take 0 away from 440, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 11:
If we divide 4400 by 686, we get 6 and a remainder of 284.
Use 6 as the next digit of our solution. 
Result so far: 63672.606
The remainder is 284 after subtracting 4116 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 12:
The number 686 fits into 2840 4 times, leaving a remainder of 96.
Write down 4 as next digit of the result. 
Result so far: 63672.6064
The remainder is 96 after subtracting 2744 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 13:
686 can be fit into 960 1 times, resulting in a remainder of 274.
Write down 1 as next digit of the result. 
Result so far: 63672.60641
Subtract 686 from 960 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 14:
The number 686 fits into 2740 3 times, leaving a remainder of 682.
The next digit of our result is 3. 
Result so far: 63672.606413
Deduct 2058 from 2740 and we're left with 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Moving on to step 15:
When dividing 6820 by 686, we get 9 with a remainder of 646.
The next digit of our result is 9. 
Result so far: 63672.6064139
If we take 6174 away from 6820, we end up with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Step 16:
6460 divided by 686 is 9 with a remainder of 286.
The next digit of our result is 9. 
Result so far: 63672.60641399
If we subtract 6174 from 6460, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Our division results in 63672.60641399 with a remaining 2.86e-07.
