631053 ÷ 78 
We want to divide 631053 by 78.

Moving on to step 1:
78 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 78

Going ahead to step 2:
78 goes into 63 0 times with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Include the next digit (1) from the dividend after 63, then repeat: 631 / 78

Moving on to step 3:
If we divide 631 by 78, we get 8 and a remainder of 7.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 7 after subtracting 624 from 631.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 78

On to step 4:
The number 78 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 80.0
Deduct 0 from 70 and we're left with 70.
Fetch the next digit (5) from the dividend, attach it to 70 and continue: 705 / 78

Going ahead to step 5:
When dividing 705 by 78, we get 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 809.0
If we take 702 away from 705, we end up with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 78

Let's proceed to step 6:
If we divide 33 by 78, we get 0 and a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 8090.0
Subtract 0 from 33 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 7:
The number 78 fits into 330 4 times, leaving a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 8090.4
If we subtract 312 from 330, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
When dividing 180 by 78, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 8090.42
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
When dividing 240 by 78, we get 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 8090.423
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
When dividing 60 by 78, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 8090.423
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
The number 78 fits into 600 7 times, leaving a remainder of 54.
The next digit of our result is 7. 
Result so far: 8090.42307
The remainder is 54 after subtracting 546 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 12:
If we divide 540 by 78, we get 6 and a remainder of 72.
The next digit of our result is 6. 
Result so far: 8090.423076
The remainder is 72 after subtracting 468 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 13:
78 can be fit into 720 9 times, resulting in a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 8090.4230769
Deduct 702 from 720 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
78 can be fit into 180 2 times, resulting in a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 8090.42307692
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 8090.42307692, with a leftover of 2.4e-08.
