We're dividing 631285 by 78 
Let's see how many times 78 fits into 631285.

Advancing to step 1:
The number 78 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 78

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
Deduct 0 from 63 and we're left with 63.
Grab the next digit (1) from the dividend, add it to 63, then carry on: 631 / 78

On to step 3:
631 divided by 78 is 8 with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 624 from 631 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 78

Step 4:
78 can be fit into 72 0 times, resulting in a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 80.0
If we take 0 away from 72, we end up with 72.
Fetch the next digit (8) from the dividend, attach it to 72 and continue: 728 / 78

Moving on to step 5:
The number 78 fits into 728 9 times, leaving a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 809.0
The remainder is 26 after subtracting 702 from 728.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 78

On to step 6:
78 can be fit into 265 3 times, resulting in a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 8093.0
The remainder is 31 after subtracting 234 from 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
78 goes into 310 3 times with a remainder of 76.
Put 3 as the next digit of the answer. 
Result so far: 8093.3
Deduct 234 from 310 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 8:
78 goes into 760 9 times with a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 8093.39
Subtract 702 from 760 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 9:
78 can be fit into 580 7 times, resulting in a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 8093.397
Deduct 546 from 580 and we're left 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.

Let's proceed to step 10:
78 goes into 340 4 times with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 8093.3974
Deduct 312 from 340 and we're left 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.

Let's proceed to step 11:
If we divide 280 by 78, we get 3 and a remainder of 46.
The next digit of our result is 3. 
Result so far: 8093.39743
If we take 234 away from 280, we end up 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.

Advancing to step 12:
460 divided by 78 is 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 8093.397435
Subtracting 390 from 460 leaves us 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.

Advancing to step 13:
If we divide 700 by 78, we get 8 and a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 8093.3974358
Subtracting 624 from 700 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 14:
78 can be fit into 760 9 times, resulting in a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 8093.39743589
Subtract 702 from 760 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The quotient of the division is 8093.39743589, and the remainder is 5.8e-08.
