Let's divide 81675970 by 490
Our goal is to divide 81675970 by 490.

Moving on to step 1:
When dividing 8 by 490, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 490

Step 2:
490 goes into 81 0 times with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Include the next digit (6) from the dividend after 81, then repeat: 816 / 490

Step 3:
490 can be fit into 816 1 times, resulting in a remainder of 326.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 326 after subtracting 490 from 816.
Bring next digit (7) of the dividend behind the 326 and repeat the process: 3267 / 490

Let's proceed to step 4:
The number 490 fits into 3267 6 times, leaving a remainder of 327.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we subtract 2940 from 3267, we get 327.
Fetch the next digit (5) from the dividend, attach it to 327 and continue: 3275 / 490

On to step 5:
If we divide 3275 by 490, we get 6 and a remainder of 335.
Record the quotient 6 as the next digit in the result. 
Result so far: 166.0
Subtracting 2940 from 3275 leaves us with 335.
Fetch the next digit (9) from the dividend, attach it to 335 and continue: 3359 / 490

Step 6:
3359 divided by 490 is 6 with a remainder of 419.
The number 6 becomes the next digit in our result. 
Result so far: 1666.0
Subtracting 2940 from 3359 leaves us with 419.
Grab the next digit (7) from the dividend, add it to 419, then carry on: 4197 / 490

On to step 7:
The number 490 fits into 4197 8 times, leaving a remainder of 277.
The next digit of our result is 8. 
Result so far: 16668.0
The remainder is 277 after subtracting 3920 from 4197.
Fetch the next digit (0) from the dividend, attach it to 277 and continue: 2770 / 490

Moving on to step 8:
490 can be fit into 2770 5 times, resulting in a remainder of 320.
Use 5 as the next digit of our solution. 
Result so far: 166685.0
Subtract 2450 from 2770 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 9:
If we divide 3200 by 490, we get 6 and a remainder of 260.
The next digit of our result is 6. 
Result so far: 166685.6
The remainder is 260 after subtracting 2940 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 10:
If we divide 2600 by 490, we get 5 and a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 166685.65
The remainder is 150 after subtracting 2450 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 11:
1500 divided by 490 is 3 with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 166685.653
The remainder is 30 after subtracting 1470 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
The number 490 fits into 300 0 times, leaving a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 166685.653
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 13:
490 goes into 3000 6 times with a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 166685.65306
Subtract 2940 from 3000 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
When dividing 600 by 490, we get 1 with a remainder of 110.
The number 1 becomes the next digit in our result. 
Result so far: 166685.653061
If we take 490 away from 600, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 15:
1100 divided by 490 is 2 with a remainder of 120.
The number 2 becomes the next digit in our result. 
Result so far: 166685.6530612
Subtracting 980 from 1100 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 16:
1200 divided by 490 is 2 with a remainder of 220.
Put 2 as the next digit of the answer. 
Result so far: 166685.65306122
If we take 980 away from 1200, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

After the division, we end up with 166685.65306122 and a remainder of 2.2e-07.
