We're dividing 81066389 by 828 
We're looking to find how many times 828 goes into 81066389.

On to step 1:
When dividing 8 by 828, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 828

Step 2:
When dividing 81 by 828, we get 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Grab the next digit (0) from the dividend, add it to 81, then carry on: 810 / 828

Step 3:
828 goes into 810 0 times with a remainder of 810.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 810 to get 810.
Append the next digit (6) from the dividend to 810 and continue with: 8106 / 828

On to step 4:
828 goes into 8106 9 times with a remainder of 654.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 7452 from 8106 leaves us with 654.
Take the next digit (6) from the dividend and append it to 654, then repeat: 6546 / 828

Step 5:
828 can be fit into 6546 7 times, resulting in a remainder of 750.
The next digit of our result is 7. 
Result so far: 97.0
Deduct 5796 from 6546 and we're left with 750.
Include the next digit (3) from the dividend after 750, then repeat: 7503 / 828

On to step 6:
828 goes into 7503 9 times with a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 979.0
If we take 7452 away from 7503, we end up with 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 828

Moving on to step 7:
828 goes into 518 0 times with a remainder of 518.
The next digit of our result is 0. 
Result so far: 9790.0
The remainder is 518 after subtracting 0 from 518.
Append the next digit (9) from the dividend to 518 and continue with: 5189 / 828

Moving on to step 8:
828 can be fit into 5189 6 times, resulting in a remainder of 221.
The number 6 becomes the next digit in our result. 
Result so far: 97906.0
If we subtract 4968 from 5189, we get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Let's proceed to step 9:
If we divide 2210 by 828, we get 2 and a remainder of 554.
The next digit of our result is 2. 
Result so far: 97906.2
Subtracting 1656 from 2210 leaves us with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Moving on to step 10:
5540 divided by 828 is 6 with a remainder of 572.
The number 6 becomes the next digit in our result. 
Result so far: 97906.26
If we subtract 4968 from 5540, we get 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Let's proceed to step 11:
When dividing 5720 by 828, we get 6 with a remainder of 752.
The number 6 becomes the next digit in our result. 
Result so far: 97906.266
The remainder is 752 after subtracting 4968 from 5720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

The final outcome is 97906.266, with a leftover of 0.0752.
