631507 ÷ 78 
Let's see how many times 78 fits into 631507.

Let's proceed to step 1:
The number 78 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 78

Going ahead to step 2:
78 goes into 63 0 times with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Fetch the next digit (1) from the dividend, attach it to 63 and continue: 631 / 78

Let's proceed to step 3:
When dividing 631 by 78, we get 8 with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 624 from 631 and we're left with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 78

Step 4:
When dividing 75 by 78, we get 0 with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Subtract 0 from 75 to get 75.
Bring next digit (0) of the dividend behind the 75 and repeat the process: 750 / 78

On to step 5:
78 can be fit into 750 9 times, resulting in a remainder of 48.
The next digit of our result is 9. 
Result so far: 809.0
Subtract 702 from 750 to get 48.
Append the next digit (7) from the dividend to 48 and continue with: 487 / 78

Moving on to step 6:
If we divide 487 by 78, we get 6 and a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 8096.0
If we subtract 468 from 487, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
190 divided by 78 is 2 with a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 8096.2
Subtract 156 from 190 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
78 can be fit into 340 4 times, resulting in a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 8096.24
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
78 goes into 280 3 times with a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 8096.243
Deduct 234 from 280 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
If we divide 460 by 78, we get 5 and a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 8096.2435
Deduct 390 from 460 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
When dividing 700 by 78, we get 8 with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 8096.24358
If we subtract 624 from 700, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 12:
78 can be fit into 760 9 times, resulting in a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 8096.243589
The remainder is 58 after subtracting 702 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 13:
If we divide 580 by 78, we get 7 and a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 8096.2435897
If we take 546 away from 580, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 14:
78 goes into 340 4 times with a remainder of 28.
The next digit of our result is 4. 
Result so far: 8096.24358974
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 8096.24358974, and the remainder is 2.8e-08.
