We're dividing 81131725 by 490 
Let's see how many times 490 fits into 81131725.

Advancing to step 1:
The number 490 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 490

Moving on to step 2:
The number 490 fits into 81 0 times, leaving a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Grab the next digit (1) from the dividend, add it to 81, then carry on: 811 / 490

Moving on to step 3:
490 goes into 811 1 times with a remainder of 321.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 490 from 811, we get 321.
Bring next digit (3) of the dividend behind the 321 and repeat the process: 3213 / 490

Step 4:
If we divide 3213 by 490, we get 6 and a remainder of 273.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 273 after subtracting 2940 from 3213.
Bring next digit (1) of the dividend behind the 273 and repeat the process: 2731 / 490

Going ahead to step 5:
490 goes into 2731 5 times with a remainder of 281.
Record the quotient 5 as the next digit in the result. 
Result so far: 165.0
If we take 2450 away from 2731, we end up with 281.
Append the next digit (7) from the dividend to 281 and continue with: 2817 / 490

Moving on to step 6:
The number 490 fits into 2817 5 times, leaving a remainder of 367.
Record the quotient 5 as the next digit in the result. 
Result so far: 1655.0
Subtracting 2450 from 2817 leaves us with 367.
Bring next digit (2) of the dividend behind the 367 and repeat the process: 3672 / 490

Going ahead to step 7:
490 goes into 3672 7 times with a remainder of 242.
Put 7 as the next digit of the answer. 
Result so far: 16557.0
Deduct 3430 from 3672 and we're left with 242.
Bring next digit (5) of the dividend behind the 242 and repeat the process: 2425 / 490

Step 8:
2425 divided by 490 is 4 with a remainder of 465.
Put 4 as the next digit of the answer. 
Result so far: 165574.0
Subtracting 1960 from 2425 leaves us with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Going ahead to step 9:
490 goes into 4650 9 times with a remainder of 240.
The next digit of our result is 9. 
Result so far: 165574.9
If we subtract 4410 from 4650, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 10:
When dividing 2400 by 490, we get 4 with a remainder of 440.
Record the quotient 4 as the next digit in the result. 
Result so far: 165574.94
Deduct 1960 from 2400 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 11:
When dividing 4400 by 490, we get 8 with a remainder of 480.
The number 8 becomes the next digit in our result. 
Result so far: 165574.948
Deduct 3920 from 4400 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 12:
If we divide 4800 by 490, we get 9 and a remainder of 390.
Put 9 as the next digit of the answer. 
Result so far: 165574.9489
If we subtract 4410 from 4800, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 13:
3900 divided by 490 is 7 with a remainder of 470.
The next digit of our result is 7. 
Result so far: 165574.94897
Deduct 3430 from 3900 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

On to step 14:
490 can be fit into 4700 9 times, resulting in a remainder of 290.
The number 9 becomes the next digit in our result. 
Result so far: 165574.948979
If we take 4410 away from 4700, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 15:
2900 divided by 490 is 5 with a remainder of 450.
Use 5 as the next digit of our solution. 
Result so far: 165574.9489795
If we subtract 2450 from 2900, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 16:
490 goes into 4500 9 times with a remainder of 90.
Write down 9 as next digit of the result. 
Result so far: 165574.94897959
If we take 4410 away from 4500, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final result is 165574.94897959 with a remainder of 9e-08.
