43986456 ÷ 687 
Let's see how many times 687 fits into 43986456.

Moving on to step 1:
The number 687 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 687

Going ahead to step 2:
The number 687 fits into 43 0 times, leaving a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 687

Advancing to step 3:
687 goes into 439 0 times with a remainder of 439.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 439 after subtracting 0 from 439.
Fetch the next digit (8) from the dividend, attach it to 439 and continue: 4398 / 687

On to step 4:
If we divide 4398 by 687, we get 6 and a remainder of 276.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 4122 from 4398 leaves us with 276.
Append the next digit (6) from the dividend to 276 and continue with: 2766 / 687

Going ahead to step 5:
The number 687 fits into 2766 4 times, leaving a remainder of 18.
The next digit of our result is 4. 
Result so far: 64.0
Deduct 2748 from 2766 and we're left with 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 687

Advancing to step 6:
184 divided by 687 is 0 with a remainder of 184.
The number 0 becomes the next digit in our result. 
Result so far: 640.0
The remainder is 184 after subtracting 0 from 184.
Append the next digit (5) from the dividend to 184 and continue with: 1845 / 687

Step 7:
1845 divided by 687 is 2 with a remainder of 471.
Put 2 as the next digit of the answer. 
Result so far: 6402.0
If we subtract 1374 from 1845, we get 471.
Fetch the next digit (6) from the dividend, attach it to 471 and continue: 4716 / 687

Moving on to step 8:
4716 divided by 687 is 6 with a remainder of 594.
Put 6 as the next digit of the answer. 
Result so far: 64026.0
Deduct 4122 from 4716 and we're left with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Going ahead to step 9:
687 goes into 5940 8 times with a remainder of 444.
Write down 8 as next digit of the result. 
Result so far: 64026.8
Subtracting 5496 from 5940 leaves us with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Going ahead to step 10:
If we divide 4440 by 687, we get 6 and a remainder of 318.
Record the quotient 6 as the next digit in the result. 
Result so far: 64026.86
If we subtract 4122 from 4440, we get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 11:
3180 divided by 687 is 4 with a remainder of 432.
Record the quotient 4 as the next digit in the result. 
Result so far: 64026.864
If we subtract 2748 from 3180, we get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 12:
If we divide 4320 by 687, we get 6 and a remainder of 198.
Write down 6 as next digit of the result. 
Result so far: 64026.8646
If we subtract 4122 from 4320, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 13:
The number 687 fits into 1980 2 times, leaving a remainder of 606.
Write down 2 as next digit of the result. 
Result so far: 64026.86462
The remainder is 606 after subtracting 1374 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Advancing to step 14:
When dividing 6060 by 687, we get 8 with a remainder of 564.
The number 8 becomes the next digit in our result. 
Result so far: 64026.864628
Subtract 5496 from 6060 to get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

On to step 15:
When dividing 5640 by 687, we get 8 with a remainder of 144.
Use 8 as the next digit of our solution. 
Result so far: 64026.8646288
Subtracting 5496 from 5640 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

In conclusion, the division gives 64026.8646288 with a balance of 1.44e-06.
