Let's divide 81531222 by 852
We want to figure out the number of times 81531222 can be divided by 852.

Let's proceed to step 1:
The number 852 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 852

Advancing to step 2:
When dividing 81 by 852, we get 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Include the next digit (5) from the dividend after 81, then repeat: 815 / 852

On to step 3:
If we divide 815 by 852, we get 0 and a remainder of 815.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 815 to get 815.
Append the next digit (3) from the dividend to 815 and continue with: 8153 / 852

Going ahead to step 4:
852 can be fit into 8153 9 times, resulting in a remainder of 485.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 7668 away from 8153, we end up with 485.
Include the next digit (1) from the dividend after 485, then repeat: 4851 / 852

Step 5:
852 can be fit into 4851 5 times, resulting in a remainder of 591.
Use 5 as the next digit of our solution. 
Result so far: 95.0
Deduct 4260 from 4851 and we're left with 591.
Bring next digit (2) of the dividend behind the 591 and repeat the process: 5912 / 852

Let's proceed to step 6:
If we divide 5912 by 852, we get 6 and a remainder of 800.
Put 6 as the next digit of the answer. 
Result so far: 956.0
If we take 5112 away from 5912, we end up with 800.
Grab the next digit (2) from the dividend, add it to 800, then carry on: 8002 / 852

Going ahead to step 7:
852 goes into 8002 9 times with a remainder of 334.
The next digit of our result is 9. 
Result so far: 9569.0
Subtracting 7668 from 8002 leaves us with 334.
Take the next digit (2) from the dividend and append it to 334, then repeat: 3342 / 852

Going ahead to step 8:
If we divide 3342 by 852, we get 3 and a remainder of 786.
The next digit of our result is 3. 
Result so far: 95693.0
Subtract 2556 from 3342 to get 786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7860, and continue the process.

Let's proceed to step 9:
852 goes into 7860 9 times with a remainder of 192.
The number 9 becomes the next digit in our result. 
Result so far: 95693.9
If we take 7668 away from 7860, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 10:
852 can be fit into 1920 2 times, resulting in a remainder of 216.
The number 2 becomes the next digit in our result. 
Result so far: 95693.92
Deduct 1704 from 1920 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 11:
852 goes into 2160 2 times with a remainder of 456.
Put 2 as the next digit of the answer. 
Result so far: 95693.922
The remainder is 456 after subtracting 1704 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Our division results in 95693.922 with a remaining 0.0456.
