We look at the division of 683731 by 78 
Let's see how many times 78 fits into 683731.

Moving on to step 1:
The number 78 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 78

Let's proceed to step 2:
78 can be fit into 68 0 times, resulting in a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Grab the next digit (3) from the dividend, add it to 68, then carry on: 683 / 78

Advancing to step 3:
683 divided by 78 is 8 with a remainder of 59.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 624 from 683, we get 59.
Fetch the next digit (7) from the dividend, attach it to 59 and continue: 597 / 78

Moving on to step 4:
78 goes into 597 7 times with a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 87.0
The remainder is 51 after subtracting 546 from 597.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 78

Moving on to step 5:
513 divided by 78 is 6 with a remainder of 45.
The next digit of our result is 6. 
Result so far: 876.0
Subtracting 468 from 513 leaves us with 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 78

Advancing to step 6:
78 goes into 451 5 times with a remainder of 61.
Write down 5 as next digit of the result. 
Result so far: 8765.0
If we subtract 390 from 451, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 7:
If we divide 610 by 78, we get 7 and a remainder of 64.
Put 7 as the next digit of the answer. 
Result so far: 8765.7
Subtract 546 from 610 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 8:
The number 78 fits into 640 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 8765.78
Subtracting 624 from 640 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.

Advancing to step 9:
78 can be fit into 160 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 8765.782
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
If we divide 40 by 78, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 8765.782
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
If we divide 400 by 78, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 8765.78205
Subtract 390 from 400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
If we divide 100 by 78, we get 1 and a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 8765.782051
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
78 can be fit into 220 2 times, resulting in a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 8765.7820512
If we take 156 away from 220, we end up 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.

Step 14:
640 divided by 78 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 8765.78205128
If we take 624 away from 640, we end up 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.

The final result is 8765.78205128 with a remainder of 1.6e-08.
