Let's divide 406648 by 78
We're looking to find how many times 78 goes into 406648.

Advancing to step 1:
4 divided by 78 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 78

Let's proceed to step 2:
78 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Grab the next digit (6) from the dividend, add it to 40, then carry on: 406 / 78

Going ahead to step 3:
78 can be fit into 406 5 times, resulting in a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 390 from 406, we get 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 78

Let's proceed to step 4:
166 divided by 78 is 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 52.0
Deduct 156 from 166 and we're left with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 78

Advancing to step 5:
The number 78 fits into 104 1 times, leaving a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 521.0
If we subtract 78 from 104, we get 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 78

Going ahead to step 6:
78 can be fit into 268 3 times, resulting in a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 5213.0
If we subtract 234 from 268, 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.

Step 7:
78 goes into 340 4 times with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 5213.4
If we take 312 away from 340, we end up 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.

On to step 8:
78 can be fit into 280 3 times, resulting in a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 5213.43
Subtracting 234 from 280 leaves us 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.

Advancing to step 9:
When dividing 460 by 78, we get 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 5213.435
Deduct 390 from 460 and we're left 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.

On to step 10:
If we divide 700 by 78, we get 8 and a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 5213.4358
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.

Advancing to step 11:
If we divide 760 by 78, we get 9 and a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 5213.43589
If we take 702 away from 760, we end up 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 12:
The number 78 fits into 580 7 times, leaving a remainder of 34.
The next digit of our result is 7. 
Result so far: 5213.435897
Deduct 546 from 580 and we're left 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.

Going ahead to step 13:
78 goes into 340 4 times with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 5213.4358974
Subtract 312 from 340 to 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 14:
If we divide 280 by 78, we get 3 and a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 5213.43589743
If we take 234 away from 280, we end up 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.

Our division results in 5213.43589743 with a remaining 4.6e-08.
