We look at the division of 84835580 by 823 
Our goal is to divide 84835580 by 823.

Advancing to step 1:
When dividing 8 by 823, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 823

Going ahead to step 2:
823 can be fit into 84 0 times, resulting in a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Take the next digit (8) from the dividend and append it to 84, then repeat: 848 / 823

Advancing to step 3:
848 divided by 823 is 1 with a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 823 from 848, we get 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 823

Moving on to step 4:
The number 823 fits into 253 0 times, leaving a remainder of 253.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 253 to get 253.
Grab the next digit (5) from the dividend, add it to 253, then carry on: 2535 / 823

Advancing to step 5:
823 can be fit into 2535 3 times, resulting in a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
Deduct 2469 from 2535 and we're left with 66.
Bring next digit (5) of the dividend behind the 66 and repeat the process: 665 / 823

On to step 6:
The number 823 fits into 665 0 times, leaving a remainder of 665.
The number 0 becomes the next digit in our result. 
Result so far: 1030.0
If we take 0 away from 665, we end up with 665.
Take the next digit (8) from the dividend and append it to 665, then repeat: 6658 / 823

Let's proceed to step 7:
When dividing 6658 by 823, we get 8 with a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 10308.0
Subtracting 6584 from 6658 leaves us with 74.
Append the next digit (0) from the dividend to 74 and continue with: 740 / 823

Let's proceed to step 8:
If we divide 740 by 823, we get 0 and a remainder of 740.
Record the quotient 0 as the next digit in the result. 
Result so far: 103080.0
If we subtract 0 from 740, we get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

On to step 9:
The number 823 fits into 7400 8 times, leaving a remainder of 816.
The next digit of our result is 8. 
Result so far: 103080.8
Deduct 6584 from 7400 and we're left with 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Let's proceed to step 10:
If we divide 8160 by 823, we get 9 and a remainder of 753.
The next digit of our result is 9. 
Result so far: 103080.89
If we take 7407 away from 8160, we end up with 753.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7530, and continue the process.

Advancing to step 11:
The number 823 fits into 7530 9 times, leaving a remainder of 123.
Write down 9 as next digit of the result. 
Result so far: 103080.899
Subtracting 7407 from 7530 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

The final result is 103080.899 with a remainder of 0.0123.
