We're dividing 80726891 by 490 
We want to divide 80726891 by 490.

Going ahead to step 1:
When dividing 8 by 490, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 490

Going ahead to step 2:
The number 490 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Take the next digit (7) from the dividend and append it to 80, then repeat: 807 / 490

Step 3:
When dividing 807 by 490, we get 1 with a remainder of 317.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 490 from 807 to get 317.
Grab the next digit (2) from the dividend, add it to 317, then carry on: 3172 / 490

Moving on to step 4:
The number 490 fits into 3172 6 times, leaving a remainder of 232.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 2940 from 3172 to get 232.
Bring next digit (6) of the dividend behind the 232 and repeat the process: 2326 / 490

Let's proceed to step 5:
If we divide 2326 by 490, we get 4 and a remainder of 366.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
The remainder is 366 after subtracting 1960 from 2326.
Include the next digit (8) from the dividend after 366, then repeat: 3668 / 490

Going ahead to step 6:
490 goes into 3668 7 times with a remainder of 238.
The number 7 becomes the next digit in our result. 
Result so far: 1647.0
Deduct 3430 from 3668 and we're left with 238.
Fetch the next digit (9) from the dividend, attach it to 238 and continue: 2389 / 490

Advancing to step 7:
2389 divided by 490 is 4 with a remainder of 429.
Put 4 as the next digit of the answer. 
Result so far: 16474.0
Deduct 1960 from 2389 and we're left with 429.
Grab the next digit (1) from the dividend, add it to 429, then carry on: 4291 / 490

On to step 8:
4291 divided by 490 is 8 with a remainder of 371.
The next digit of our result is 8. 
Result so far: 164748.0
Subtract 3920 from 4291 to get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Step 9:
When dividing 3710 by 490, we get 7 with a remainder of 280.
Record the quotient 7 as the next digit in the result. 
Result so far: 164748.7
Subtract 3430 from 3710 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 10:
When dividing 2800 by 490, we get 5 with a remainder of 350.
Record the quotient 5 as the next digit in the result. 
Result so far: 164748.75
The remainder is 350 after subtracting 2450 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 11:
490 goes into 3500 7 times with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 164748.757
Subtract 3430 from 3500 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 12:
700 divided by 490 is 1 with a remainder of 210.
Record the quotient 1 as the next digit in the result. 
Result so far: 164748.7571
If we subtract 490 from 700, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 13:
490 goes into 2100 4 times with a remainder of 140.
Record the quotient 4 as the next digit in the result. 
Result so far: 164748.75714
Subtract 1960 from 2100 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 14:
490 goes into 1400 2 times with a remainder of 420.
Use 2 as the next digit of our solution. 
Result so far: 164748.757142
Deduct 980 from 1400 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 15:
4200 divided by 490 is 8 with a remainder of 280.
The number 8 becomes the next digit in our result. 
Result so far: 164748.7571428
If we take 3920 away from 4200, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 16:
If we divide 2800 by 490, we get 5 and a remainder of 350.
Record the quotient 5 as the next digit in the result. 
Result so far: 164748.75714285
Subtract 2450 from 2800 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

The quotient of the division is 164748.75714285, and the remainder is 3.5e-07.
