658960 divided by 78 
We want to divide 658960 by 78.

On to step 1:
The number 78 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 78

On to step 2:
78 can be fit into 65 0 times, resulting in a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Fetch the next digit (8) from the dividend, attach it to 65 and continue: 658 / 78

Step 3:
78 can be fit into 658 8 times, resulting in a remainder of 34.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 624 from 658 leaves us with 34.
Fetch the next digit (9) from the dividend, attach it to 34 and continue: 349 / 78

Step 4:
When dividing 349 by 78, we get 4 with a remainder of 37.
Use 4 as the next digit of our solution. 
Result so far: 84.0
The remainder is 37 after subtracting 312 from 349.
Bring next digit (6) of the dividend behind the 37 and repeat the process: 376 / 78

Going ahead to step 5:
78 can be fit into 376 4 times, resulting in a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 844.0
The remainder is 64 after subtracting 312 from 376.
Grab the next digit (0) from the dividend, add it to 64, then carry on: 640 / 78

Advancing to step 6:
640 divided by 78 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 8448.0
Subtracting 624 from 640 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
78 goes into 160 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 8448.2
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
78 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 8448.2
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
78 goes into 400 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 8448.205
Deduct 390 from 400 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
The number 78 fits into 100 1 times, leaving a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 8448.2051
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
When dividing 220 by 78, we get 2 with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 8448.20512
If we take 156 away from 220, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
The number 78 fits into 640 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 8448.205128
Subtract 624 from 640 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
The number 78 fits into 160 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 8448.2051282
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
40 divided by 78 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 8448.2051282
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 8448.2051282, with a leftover of 4e-08.
