We look at the division of 77781047 by 491 
We want to figure out the number of times 77781047 can be divided by 491.

Let's proceed to step 1:
7 divided by 491 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 491

Moving on to step 2:
491 goes into 77 0 times with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 491

Moving on to step 3:
777 divided by 491 is 1 with a remainder of 286.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 491 from 777 and we're left with 286.
Take the next digit (8) from the dividend and append it to 286, then repeat: 2868 / 491

Let's proceed to step 4:
When dividing 2868 by 491, we get 5 with a remainder of 413.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 2455 from 2868, we get 413.
Take the next digit (1) from the dividend and append it to 413, then repeat: 4131 / 491

Advancing to step 5:
491 goes into 4131 8 times with a remainder of 203.
The next digit of our result is 8. 
Result so far: 158.0
Deduct 3928 from 4131 and we're left with 203.
Take the next digit (0) from the dividend and append it to 203, then repeat: 2030 / 491

Advancing to step 6:
The number 491 fits into 2030 4 times, leaving a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 1584.0
Subtract 1964 from 2030 to get 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 491

On to step 7:
491 goes into 664 1 times with a remainder of 173.
Record the quotient 1 as the next digit in the result. 
Result so far: 15841.0
Subtracting 491 from 664 leaves us with 173.
Include the next digit (7) from the dividend after 173, then repeat: 1737 / 491

Moving on to step 8:
If we divide 1737 by 491, we get 3 and a remainder of 264.
Put 3 as the next digit of the answer. 
Result so far: 158413.0
The remainder is 264 after subtracting 1473 from 1737.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 9:
The number 491 fits into 2640 5 times, leaving a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 158413.5
Subtracting 2455 from 2640 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 10:
When dividing 1850 by 491, we get 3 with a remainder of 377.
Use 3 as the next digit of our solution. 
Result so far: 158413.53
If we subtract 1473 from 1850, we get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Moving on to step 11:
491 goes into 3770 7 times with a remainder of 333.
Put 7 as the next digit of the answer. 
Result so far: 158413.537
If we subtract 3437 from 3770, we get 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

On to step 12:
3330 divided by 491 is 6 with a remainder of 384.
Put 6 as the next digit of the answer. 
Result so far: 158413.5376
Subtract 2946 from 3330 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 13:
491 can be fit into 3840 7 times, resulting in a remainder of 403.
Use 7 as the next digit of our solution. 
Result so far: 158413.53767
If we take 3437 away from 3840, we end up with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Step 14:
The number 491 fits into 4030 8 times, leaving a remainder of 102.
Record the quotient 8 as the next digit in the result. 
Result so far: 158413.537678
Subtracting 3928 from 4030 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 15:
491 can be fit into 1020 2 times, resulting in a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 158413.5376782
Subtract 982 from 1020 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 16:
If we divide 380 by 491, we get 0 and a remainder of 380.
The next digit of our result is 0. 
Result so far: 158413.5376782
Deduct 0 from 380 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Our division results in 158413.5376782 with a remaining 3.8e-07.
