We look at the division of 649123 by 78 
We want to divide 649123 by 78.

On to step 1:
The number 78 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 78

Advancing to step 2:
The number 78 fits into 64 0 times, leaving a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Fetch the next digit (9) from the dividend, attach it to 64 and continue: 649 / 78

Moving on to step 3:
When dividing 649 by 78, we get 8 with a remainder of 25.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 25 after subtracting 624 from 649.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 78

Let's proceed to step 4:
78 goes into 251 3 times with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 83.0
Subtracting 234 from 251 leaves us with 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 78

Let's proceed to step 5:
When dividing 172 by 78, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 832.0
Subtract 156 from 172 to get 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 78

Going ahead to step 6:
163 divided by 78 is 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 8322.0
If we subtract 156 from 163, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
If we divide 70 by 78, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 8322.0
If we subtract 0 from 70, we get 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 8:
The number 78 fits into 700 8 times, leaving a remainder of 76.
The next digit of our result is 8. 
Result so far: 8322.08
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.

Let's proceed to step 9:
When dividing 760 by 78, we get 9 with a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 8322.089
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.

Advancing 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: 8322.0897
The remainder is 34 after subtracting 546 from 580.
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:
The number 78 fits into 340 4 times, leaving a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 8322.08974
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
78 goes into 280 3 times with a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 8322.089743
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.

Step 13:
78 goes into 460 5 times with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 8322.0897435
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.

Step 14:
The number 78 fits into 700 8 times, leaving a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 8322.08974358
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.

The final result is 8322.08974358 with a remainder of 7.6e-08.
