491440 ÷ 78 
Our goal is to divide 491440 by 78.

Advancing to step 1:
4 divided by 78 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 78

On to step 2:
When dividing 49 by 78, we get 0 with a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Include the next digit (1) from the dividend after 49, then repeat: 491 / 78

Step 3:
If we divide 491 by 78, we get 6 and a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 468 from 491 to get 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 78

Moving on to step 4:
If we divide 234 by 78, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtracting 234 from 234 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 78

Advancing to step 5:
78 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 630.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 78

Going ahead to step 6:
If we divide 40 by 78, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 6300.0
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.

Let's proceed to step 7:
400 divided by 78 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 6300.5
If we take 390 away from 400, we end up 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 8:
78 goes into 100 1 times with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 6300.51
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 9:
220 divided by 78 is 2 with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 6300.512
Subtract 156 from 220 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
If we divide 640 by 78, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 6300.5128
The remainder is 16 after subtracting 624 from 640.
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 11:
If we divide 160 by 78, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 6300.51282
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.

On to step 12:
If we divide 40 by 78, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 6300.51282
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.

Advancing to step 13:
78 goes into 400 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 6300.5128205
Subtracting 390 from 400 leaves us 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.

Step 14:
The number 78 fits into 100 1 times, leaving a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 6300.51282051
Deduct 78 from 100 and we're left 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.

The final outcome is 6300.51282051, with a leftover of 2.2e-08.
