We're dividing 631104 by 78 
We want to figure out the number of times 631104 can be divided by 78.

Let's proceed to step 1:
78 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 78

Step 2:
63 divided by 78 is 0 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.
Bring next digit (1) of the dividend behind the 63 and repeat the process: 631 / 78

Moving on to step 3:
78 goes into 631 8 times with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 624 from 631 to get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 78

Moving on to step 4:
71 divided by 78 is 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 80.0
If we subtract 0 from 71, we get 71.
Bring next digit (0) of the dividend behind the 71 and repeat the process: 710 / 78

Advancing to step 5:
78 can be fit into 710 9 times, resulting in a remainder of 8.
The next digit of our result is 9. 
Result so far: 809.0
If we subtract 702 from 710, we get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 78

Going ahead to step 6:
84 divided by 78 is 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 8091.0
If we take 78 away from 84, we end up 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.

Going ahead to step 7:
78 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 8091.0
Subtracting 0 from 60 leaves us with 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 8:
78 goes into 600 7 times with a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 8091.07
Subtracting 546 from 600 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 9:
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: 8091.076
If we take 468 away from 540, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 10:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 8091.0769
Subtract 702 from 720 to 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 11:
180 divided by 78 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 8091.07692
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
When dividing 240 by 78, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 8091.076923
If we subtract 234 from 240, we get 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 13:
The number 78 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 8091.076923
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
The number 78 fits into 600 7 times, leaving a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 8091.07692307
If we subtract 546 from 600, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 8091.07692307 and a remainder of 5.4e-08.
