3973 divided by 78 
We want to divide 3973 by 78.

Step 1:
The number 78 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 78

Let's proceed to step 2:
If we divide 39 by 78, we get 0 and a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Take the next digit (7) from the dividend and append it to 39, then repeat: 397 / 78

Advancing to step 3:
78 goes into 397 5 times with a remainder of 7.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 390 from 397 leaves us with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 78

Let's proceed to step 4:
If we divide 73 by 78, we get 0 and a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Deduct 0 from 73 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 5:
78 can be fit into 730 9 times, resulting in a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 50.9
The remainder is 28 after subtracting 702 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 6:
If we divide 280 by 78, we get 3 and a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 50.93
Deduct 234 from 280 and we're left 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.

Step 7:
When dividing 460 by 78, we get 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 50.935
The remainder is 70 after subtracting 390 from 460.
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 8:
If we divide 700 by 78, we get 8 and a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 50.9358
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.

On to step 9:
When dividing 760 by 78, we get 9 with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 50.93589
Deduct 702 from 760 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 10:
If we divide 580 by 78, we get 7 and a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 50.935897
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
340 divided by 78 is 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 50.9358974
If we subtract 312 from 340, we get 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 12:
78 goes into 280 3 times with a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 50.93589743
Subtract 234 from 280 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The quotient of the division is 50.93589743, and the remainder is 4.6e-08.
