Let's divide 31364913 by 78
We want to divide 31364913 by 78.

Step 1:
3 divided by 78 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 78

On to step 2:
The number 78 fits into 31 0 times, leaving a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 78

Going ahead to step 3:
78 can be fit into 313 4 times, resulting in a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 1 after subtracting 312 from 313.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 78

Moving on to step 4:
78 can be fit into 16 0 times, resulting in a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtract 0 from 16 to get 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 78

Going ahead to step 5:
164 divided by 78 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 402.0
Subtracting 156 from 164 leaves us with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 78

Step 6:
78 can be fit into 89 1 times, resulting in a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 4021.0
If we take 78 away from 89, we end up with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 78

Step 7:
78 can be fit into 111 1 times, resulting in a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 40211.0
If we take 78 away from 111, we end up with 33.
Include the next digit (3) from the dividend after 33, then repeat: 333 / 78

On to step 8:
78 goes into 333 4 times with a remainder of 21.
Write down 4 as next digit of the result. 
Result so far: 402114.0
Deduct 312 from 333 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
When dividing 210 by 78, we get 2 with a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 402114.2
If we subtract 156 from 210, 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.

Going ahead to step 10:
78 goes into 540 6 times with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 402114.26
Deduct 468 from 540 and we're left 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.

Step 11:
The number 78 fits into 720 9 times, leaving a remainder of 18.
The next digit of our result is 9. 
Result so far: 402114.269
If we take 702 away from 720, we end up 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.

Step 12:
78 goes into 180 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 402114.2692
If we subtract 156 from 180, we 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.

On to step 13:
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: 402114.26923
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 14:
If we divide 60 by 78, we get 0 and a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 402114.26923
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.

Advancing to step 15:
600 divided by 78 is 7 with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 402114.2692307
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 16:
78 can be fit into 540 6 times, resulting in a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 402114.26923076
Deduct 468 from 540 and we're left 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.

After the division, we end up with 402114.26923076 and a remainder of 7.2e-08.
