We divide 51657964 by 78
We want to divide 51657964 by 78.

On to step 1:
When dividing 5 by 78, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 78

Going ahead to step 2:
51 divided by 78 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Include the next digit (6) from the dividend after 51, then repeat: 516 / 78

Step 3:
78 goes into 516 6 times with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 48 after subtracting 468 from 516.
Grab the next digit (5) from the dividend, add it to 48, then carry on: 485 / 78

Let's proceed to step 4:
The number 78 fits into 485 6 times, leaving a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 66.0
If we take 468 away from 485, we end up with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 78

Step 5:
If we divide 177 by 78, we get 2 and a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 662.0
Deduct 156 from 177 and we're left with 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 78

Step 6:
When dividing 219 by 78, we get 2 with a remainder of 63.
Record the quotient 2 as the next digit in the result. 
Result so far: 6622.0
If we subtract 156 from 219, we get 63.
Bring next digit (6) of the dividend behind the 63 and repeat the process: 636 / 78

On to step 7:
The number 78 fits into 636 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 66228.0
If we subtract 624 from 636, we get 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 78

Going ahead to step 8:
The number 78 fits into 124 1 times, leaving a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 662281.0
If we subtract 78 from 124, we 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.

Advancing to step 9:
460 divided by 78 is 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 662281.5
If we take 390 away from 460, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
700 divided by 78 is 8 with a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 662281.58
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.

Let's proceed to step 11:
78 can be fit into 760 9 times, resulting in a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 662281.589
If we subtract 702 from 760, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 12:
580 divided by 78 is 7 with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 662281.5897
If we take 546 away from 580, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 13:
78 can be fit into 340 4 times, resulting in a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 662281.58974
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.

Moving on to step 14:
When dividing 280 by 78, we get 3 with a remainder of 46.
The next digit of our result is 3. 
Result so far: 662281.589743
The remainder is 46 after subtracting 234 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 15:
460 divided by 78 is 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 662281.5897435
Subtracting 390 from 460 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 16:
700 divided by 78 is 8 with a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 662281.58974358
Deduct 624 from 700 and we're left 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.

Our division results in 662281.58974358 with a remaining 7.6e-08.
