We look at the division of 491561 by 78 
We want to figure out the number of times 491561 can be divided by 78.

On to step 1:
4 divided by 78 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 78

On to step 2:
The number 78 fits into 49 0 times, leaving a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Append the next digit (1) from the dividend to 49 and continue with: 491 / 78

Moving on to step 3:
491 divided by 78 is 6 with a remainder of 23.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 468 from 491 leaves us with 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 78

Let's proceed to step 4:
The number 78 fits into 235 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
If we take 234 away from 235, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 78

Step 5:
The number 78 fits into 16 0 times, leaving a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 630.0
Subtract 0 from 16 to get 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 78

Step 6:
When dividing 161 by 78, we get 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 6302.0
Deduct 156 from 161 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
78 can be fit into 50 0 times, resulting in a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 6302.0
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
When dividing 500 by 78, we get 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 6302.06
The remainder is 32 after subtracting 468 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
320 divided by 78 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 6302.064
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
78 goes into 80 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 6302.0641
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
The number 78 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 6302.0641
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
78 can be fit into 200 2 times, resulting in a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 6302.064102
Deduct 156 from 200 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
78 can be fit into 440 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 6302.0641025
If we take 390 away from 440, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
The number 78 fits into 500 6 times, leaving a remainder of 32.
The next digit of our result is 6. 
Result so far: 6302.06410256
Deduct 468 from 500 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 6302.06410256, and the remainder is 3.2e-08.
