Let's divide 310146 by 78
Our goal is to divide 310146 by 78.

Let's proceed to step 1:
3 divided by 78 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 78

Let's proceed to step 2:
When dividing 31 by 78, we get 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 78

Let's proceed to step 3:
If we divide 310 by 78, we get 3 and a remainder of 76.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 234 from 310, we get 76.
Fetch the next digit (1) from the dividend, attach it to 76 and continue: 761 / 78

Step 4:
When dividing 761 by 78, we get 9 with a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we subtract 702 from 761, we get 59.
Bring next digit (4) of the dividend behind the 59 and repeat the process: 594 / 78

Going ahead to step 5:
When dividing 594 by 78, we get 7 with a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 397.0
Subtract 546 from 594 to get 48.
Take the next digit (6) from the dividend and append it to 48, then repeat: 486 / 78

Step 6:
78 goes into 486 6 times with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 3976.0
Deduct 468 from 486 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.

Moving on to step 7:
78 can be fit into 180 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 3976.2
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 8:
When dividing 240 by 78, we get 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3976.23
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.

Step 9:
78 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 3976.23
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 10:
78 can be fit into 600 7 times, resulting in a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 3976.2307
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.

Moving on to step 11:
540 divided by 78 is 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 3976.23076
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 12:
720 divided by 78 is 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 3976.230769
If we subtract 702 from 720, 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.

Step 13:
78 can be fit into 180 2 times, resulting in a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 3976.2307692
If we take 156 away from 180, we end up 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.

Advancing to step 14:
240 divided by 78 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 3976.23076923
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.

The quotient of the division is 3976.23076923, and the remainder is 6e-09.
