We're dividing 87852290 by 821 
We're looking to find how many times 821 goes into 87852290.

Moving on to step 1:
821 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 821

Step 2:
When dividing 87 by 821, we get 0 with a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Grab the next digit (8) from the dividend, add it to 87, then carry on: 878 / 821

Advancing to step 3:
If we divide 878 by 821, we get 1 and a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 821 from 878 leaves us with 57.
Include the next digit (5) from the dividend after 57, then repeat: 575 / 821

Moving on to step 4:
575 divided by 821 is 0 with a remainder of 575.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 575 to get 575.
Take the next digit (2) from the dividend and append it to 575, then repeat: 5752 / 821

Going ahead to step 5:
If we divide 5752 by 821, we get 7 and a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
If we subtract 5747 from 5752, we get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 821

Going ahead to step 6:
The number 821 fits into 52 0 times, leaving a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 1070.0
The remainder is 52 after subtracting 0 from 52.
Append the next digit (9) from the dividend to 52 and continue with: 529 / 821

On to step 7:
The number 821 fits into 529 0 times, leaving a remainder of 529.
Write down 0 as next digit of the result. 
Result so far: 10700.0
Deduct 0 from 529 and we're left with 529.
Include the next digit (0) from the dividend after 529, then repeat: 5290 / 821

Going ahead to step 8:
5290 divided by 821 is 6 with a remainder of 364.
Write down 6 as next digit of the result. 
Result so far: 107006.0
Subtract 4926 from 5290 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 9:
The number 821 fits into 3640 4 times, leaving a remainder of 356.
Put 4 as the next digit of the answer. 
Result so far: 107006.4
Deduct 3284 from 3640 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Advancing to step 10:
If we divide 3560 by 821, we get 4 and a remainder of 276.
The number 4 becomes the next digit in our result. 
Result so far: 107006.44
Subtract 3284 from 3560 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

After the division, we end up with 107006.44 and a remainder of 0.276.
