800490 ÷ 84 
We want to figure out the number of times 800490 can be divided by 84.

Let's proceed to step 1:
When dividing 8 by 84, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 84

On to step 2:
84 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Append the next digit (0) from the dividend to 80 and continue with: 800 / 84

Going ahead to step 3:
84 goes into 800 9 times with a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 756 from 800, we get 44.
Append the next digit (4) from the dividend to 44 and continue with: 444 / 84

Going ahead to step 4:
The number 84 fits into 444 5 times, leaving a remainder of 24.
The next digit of our result is 5. 
Result so far: 95.0
The remainder is 24 after subtracting 420 from 444.
Bring next digit (9) of the dividend behind the 24 and repeat the process: 249 / 84

On to step 5:
The number 84 fits into 249 2 times, leaving a remainder of 81.
Record the quotient 2 as the next digit in the result. 
Result so far: 952.0
The remainder is 81 after subtracting 168 from 249.
Bring next digit (0) of the dividend behind the 81 and repeat the process: 810 / 84

Let's proceed to step 6:
If we divide 810 by 84, we get 9 and a remainder of 54.
The next digit of our result is 9. 
Result so far: 9529.0
Deduct 756 from 810 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 7:
540 divided by 84 is 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 9529.6
The remainder is 36 after subtracting 504 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
84 can be fit into 360 4 times, resulting in a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 9529.64
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
If we divide 240 by 84, we get 2 and a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 9529.642
Subtract 168 from 240 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 10:
84 goes into 720 8 times with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 9529.6428
Subtracting 672 from 720 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
When dividing 480 by 84, we get 5 with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 9529.64285
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
84 goes into 600 7 times with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 9529.642857
If we subtract 588 from 600, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
When dividing 120 by 84, we get 1 with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 9529.6428571
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
When dividing 360 by 84, we get 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 9529.64285714
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 9529.64285714, with a leftover of 2.4e-08.
