81476778 divided by 491 
We want to figure out the number of times 81476778 can be divided by 491.

Advancing to step 1:
If we divide 8 by 491, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 491

Let's proceed to step 2:
When dividing 81 by 491, we get 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Include the next digit (4) from the dividend after 81, then repeat: 814 / 491

On to step 3:
491 can be fit into 814 1 times, resulting in a remainder of 323.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 491 away from 814, we end up with 323.
Grab the next digit (7) from the dividend, add it to 323, then carry on: 3237 / 491

Moving on to step 4:
491 goes into 3237 6 times with a remainder of 291.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 291 after subtracting 2946 from 3237.
Include the next digit (6) from the dividend after 291, then repeat: 2916 / 491

Moving on to step 5:
When dividing 2916 by 491, we get 5 with a remainder of 461.
Use 5 as the next digit of our solution. 
Result so far: 165.0
Subtract 2455 from 2916 to get 461.
Fetch the next digit (7) from the dividend, attach it to 461 and continue: 4617 / 491

On to step 6:
4617 divided by 491 is 9 with a remainder of 198.
Put 9 as the next digit of the answer. 
Result so far: 1659.0
Subtracting 4419 from 4617 leaves us with 198.
Fetch the next digit (7) from the dividend, attach it to 198 and continue: 1987 / 491

Advancing to step 7:
491 can be fit into 1987 4 times, resulting in a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 16594.0
Subtracting 1964 from 1987 leaves us with 23.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 491

On to step 8:
491 can be fit into 238 0 times, resulting in a remainder of 238.
Record the quotient 0 as the next digit in the result. 
Result so far: 165940.0
The remainder is 238 after subtracting 0 from 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 9:
491 can be fit into 2380 4 times, resulting in a remainder of 416.
Put 4 as the next digit of the answer. 
Result so far: 165940.4
If we take 1964 away from 2380, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 10:
The number 491 fits into 4160 8 times, leaving a remainder of 232.
Record the quotient 8 as the next digit in the result. 
Result so far: 165940.48
The remainder is 232 after subtracting 3928 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 11:
If we divide 2320 by 491, we get 4 and a remainder of 356.
Put 4 as the next digit of the answer. 
Result so far: 165940.484
Subtract 1964 from 2320 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 12:
491 can be fit into 3560 7 times, resulting in a remainder of 123.
The number 7 becomes the next digit in our result. 
Result so far: 165940.4847
The remainder is 123 after subtracting 3437 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 13:
The number 491 fits into 1230 2 times, leaving a remainder of 248.
Write down 2 as next digit of the result. 
Result so far: 165940.48472
Deduct 982 from 1230 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 14:
2480 divided by 491 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 165940.484725
If we take 2455 away from 2480, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 15:
The number 491 fits into 250 0 times, leaving a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 165940.484725
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 16:
491 goes into 2500 5 times with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 165940.48472505
The remainder is 45 after subtracting 2455 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 165940.48472505, with a leftover of 4.5e-08.
