686947 divided by 78 
We want to divide 686947 by 78.

Moving on to step 1:
The number 78 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 78

Step 2:
If we divide 68 by 78, we get 0 and a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Fetch the next digit (6) from the dividend, attach it to 68 and continue: 686 / 78

On to step 3:
686 divided by 78 is 8 with a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 624 from 686 to get 62.
Append the next digit (9) from the dividend to 62 and continue with: 629 / 78

On to step 4:
629 divided by 78 is 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 88.0
Deduct 624 from 629 and we're left with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 78

On to step 5:
54 divided by 78 is 0 with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 880.0
Deduct 0 from 54 and we're left with 54.
Fetch the next digit (7) from the dividend, attach it to 54 and continue: 547 / 78

Step 6:
If we divide 547 by 78, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 8807.0
If we subtract 546 from 547, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
If we divide 10 by 78, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 8807.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
78 goes into 100 1 times with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 8807.01
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
The number 78 fits into 220 2 times, leaving a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 8807.012
The remainder is 64 after subtracting 156 from 220.
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 10:
If we divide 640 by 78, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 8807.0128
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
The number 78 fits into 160 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 8807.01282
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.

Going ahead to step 12:
If we divide 40 by 78, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 8807.01282
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.

Going ahead to step 13:
78 goes into 400 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 8807.0128205
The remainder is 10 after subtracting 390 from 400.
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 14:
100 divided by 78 is 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 8807.01282051
If we take 78 away from 100, we end up 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.

The final outcome is 8807.01282051, with a leftover of 2.2e-08.
