Let's divide 80513967 by 490
We want to figure out the number of times 80513967 can be divided by 490.

Going ahead to step 1:
490 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 490

Let's proceed to step 2:
80 divided by 490 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Take the next digit (5) from the dividend and append it to 80, then repeat: 805 / 490

Step 3:
490 can be fit into 805 1 times, resulting in a remainder of 315.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 490 from 805 and we're left with 315.
Bring next digit (1) of the dividend behind the 315 and repeat the process: 3151 / 490

Step 4:
490 goes into 3151 6 times with a remainder of 211.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 2940 from 3151 to get 211.
Grab the next digit (3) from the dividend, add it to 211, then carry on: 2113 / 490

Advancing to step 5:
The number 490 fits into 2113 4 times, leaving a remainder of 153.
The number 4 becomes the next digit in our result. 
Result so far: 164.0
The remainder is 153 after subtracting 1960 from 2113.
Fetch the next digit (9) from the dividend, attach it to 153 and continue: 1539 / 490

Step 6:
The number 490 fits into 1539 3 times, leaving a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 1643.0
Subtract 1470 from 1539 to get 69.
Append the next digit (6) from the dividend to 69 and continue with: 696 / 490

Going ahead to step 7:
490 can be fit into 696 1 times, resulting in a remainder of 206.
Put 1 as the next digit of the answer. 
Result so far: 16431.0
The remainder is 206 after subtracting 490 from 696.
Grab the next digit (7) from the dividend, add it to 206, then carry on: 2067 / 490

Advancing to step 8:
2067 divided by 490 is 4 with a remainder of 107.
The next digit of our result is 4. 
Result so far: 164314.0
Subtracting 1960 from 2067 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 9:
If we divide 1070 by 490, we get 2 and a remainder of 90.
Put 2 as the next digit of the answer. 
Result so far: 164314.2
If we take 980 away from 1070, 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.

On to step 10:
The number 490 fits into 900 1 times, leaving a remainder of 410.
The next digit of our result is 1. 
Result so far: 164314.21
The remainder is 410 after subtracting 490 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 11:
The number 490 fits into 4100 8 times, leaving a remainder of 180.
The number 8 becomes the next digit in our result. 
Result so far: 164314.218
If we take 3920 away from 4100, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 12:
1800 divided by 490 is 3 with a remainder of 330.
Record the quotient 3 as the next digit in the result. 
Result so far: 164314.2183
The remainder is 330 after subtracting 1470 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 13:
If we divide 3300 by 490, we get 6 and a remainder of 360.
The number 6 becomes the next digit in our result. 
Result so far: 164314.21836
The remainder is 360 after subtracting 2940 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 14:
490 can be fit into 3600 7 times, resulting in a remainder of 170.
Write down 7 as next digit of the result. 
Result so far: 164314.218367
If we take 3430 away from 3600, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 15:
The number 490 fits into 1700 3 times, leaving a remainder of 230.
Record the quotient 3 as the next digit in the result. 
Result so far: 164314.2183673
The remainder is 230 after subtracting 1470 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 16:
2300 divided by 490 is 4 with a remainder of 340.
The number 4 becomes the next digit in our result. 
Result so far: 164314.21836734
Subtract 1960 from 2300 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Our division results in 164314.21836734 with a remaining 3.4e-07.
