We're dividing 81458022 by 491 
Let's see how many times 491 fits into 81458022.

Moving on to step 1:
491 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 491

Advancing to step 2:
When dividing 81 by 491, we get 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Fetch the next digit (4) from the dividend, attach it to 81 and continue: 814 / 491

Moving on to step 3:
814 divided by 491 is 1 with a remainder of 323.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 491 from 814, we get 323.
Fetch the next digit (5) from the dividend, attach it to 323 and continue: 3235 / 491

Moving on to step 4:
3235 divided by 491 is 6 with a remainder of 289.
The next digit of our result is 6. 
Result so far: 16.0
Subtract 2946 from 3235 to get 289.
Fetch the next digit (8) from the dividend, attach it to 289 and continue: 2898 / 491

Moving on to step 5:
The number 491 fits into 2898 5 times, leaving a remainder of 443.
Put 5 as the next digit of the answer. 
Result so far: 165.0
If we take 2455 away from 2898, we end up with 443.
Grab the next digit (0) from the dividend, add it to 443, then carry on: 4430 / 491

Going ahead to step 6:
When dividing 4430 by 491, we get 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 1659.0
Deduct 4419 from 4430 and we're left with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 491

On to step 7:
When dividing 112 by 491, we get 0 with a remainder of 112.
The next digit of our result is 0. 
Result so far: 16590.0
Subtracting 0 from 112 leaves us with 112.
Take the next digit (2) from the dividend and append it to 112, then repeat: 1122 / 491

On to step 8:
The number 491 fits into 1122 2 times, leaving a remainder of 140.
The next digit of our result is 2. 
Result so far: 165902.0
Subtracting 982 from 1122 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 9:
491 can be fit into 1400 2 times, resulting in a remainder of 418.
The number 2 becomes the next digit in our result. 
Result so far: 165902.2
Deduct 982 from 1400 and we're left with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Step 10:
When dividing 4180 by 491, we get 8 with a remainder of 252.
The next digit of our result is 8. 
Result so far: 165902.28
Subtract 3928 from 4180 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 11:
The number 491 fits into 2520 5 times, leaving a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 165902.285
If we take 2455 away from 2520, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 12:
The number 491 fits into 650 1 times, leaving a remainder of 159.
The next digit of our result is 1. 
Result so far: 165902.2851
The remainder is 159 after subtracting 491 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Advancing to step 13:
When dividing 1590 by 491, we get 3 with a remainder of 117.
The number 3 becomes the next digit in our result. 
Result so far: 165902.28513
If we take 1473 away from 1590, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 14:
When dividing 1170 by 491, we get 2 with a remainder of 188.
The number 2 becomes the next digit in our result. 
Result so far: 165902.285132
If we take 982 away from 1170, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 15:
491 goes into 1880 3 times with a remainder of 407.
The next digit of our result is 3. 
Result so far: 165902.2851323
Deduct 1473 from 1880 and we're left with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Step 16:
4070 divided by 491 is 8 with a remainder of 142.
Put 8 as the next digit of the answer. 
Result so far: 165902.28513238
If we subtract 3928 from 4070, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

After the division, we end up with 165902.28513238 and a remainder of 1.42e-07.
