We're dividing 81864609 by 824 
We want to divide 81864609 by 824.

Moving on to step 1:
When dividing 8 by 824, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 824

Moving on to step 2:
824 can be fit into 81 0 times, resulting in a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Take the next digit (8) from the dividend and append it to 81, then repeat: 818 / 824

On to step 3:
When dividing 818 by 824, we get 0 with a remainder of 818.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 818 to get 818.
Bring next digit (6) of the dividend behind the 818 and repeat the process: 8186 / 824

Let's proceed to step 4:
If we divide 8186 by 824, we get 9 and a remainder of 770.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 7416 away from 8186, we end up with 770.
Bring next digit (4) of the dividend behind the 770 and repeat the process: 7704 / 824

Step 5:
824 goes into 7704 9 times with a remainder of 288.
The next digit of our result is 9. 
Result so far: 99.0
If we take 7416 away from 7704, we end up with 288.
Include the next digit (6) from the dividend after 288, then repeat: 2886 / 824

Step 6:
The number 824 fits into 2886 3 times, leaving a remainder of 414.
The number 3 becomes the next digit in our result. 
Result so far: 993.0
Subtract 2472 from 2886 to get 414.
Bring next digit (0) of the dividend behind the 414 and repeat the process: 4140 / 824

Moving on to step 7:
When dividing 4140 by 824, we get 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 9935.0
The remainder is 20 after subtracting 4120 from 4140.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 824

Let's proceed to step 8:
The number 824 fits into 209 0 times, leaving a remainder of 209.
Write down 0 as next digit of the result. 
Result so far: 99350.0
If we subtract 0 from 209, we get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 9:
824 goes into 2090 2 times with a remainder of 442.
The next digit of our result is 2. 
Result so far: 99350.2
If we take 1648 away from 2090, we end up with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Advancing to step 10:
824 goes into 4420 5 times with a remainder of 300.
Record the quotient 5 as the next digit in the result. 
Result so far: 99350.25
Subtracting 4120 from 4420 leaves us 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.

On to step 11:
If we divide 3000 by 824, we get 3 and a remainder of 528.
Record the quotient 3 as the next digit in the result. 
Result so far: 99350.253
If we take 2472 away from 3000, we end up with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 12:
If we divide 5280 by 824, we get 6 and a remainder of 336.
Write down 6 as next digit of the result. 
Result so far: 99350.2536
Deduct 4944 from 5280 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 13:
When dividing 3360 by 824, we get 4 with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 99350.25364
If we take 3296 away from 3360, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 14:
824 can be fit into 640 0 times, resulting in a remainder of 640.
Use 0 as the next digit of our solution. 
Result so far: 99350.25364
Deduct 0 from 640 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 15:
824 can be fit into 6400 7 times, resulting in a remainder of 632.
The next digit of our result is 7. 
Result so far: 99350.2536407
The remainder is 632 after subtracting 5768 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Let's proceed to step 16:
The number 824 fits into 6320 7 times, leaving a remainder of 552.
Use 7 as the next digit of our solution. 
Result so far: 99350.25364077
Subtracting 5768 from 6320 leaves us with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

The quotient of the division is 99350.25364077, and the remainder is 5.52e-07.
