Let's divide 52587358 by 821
We're looking to find how many times 821 goes into 52587358.

Step 1:
5 divided by 821 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 821

Going ahead to step 2:
If we divide 52 by 821, we get 0 and a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Grab the next digit (5) from the dividend, add it to 52, then carry on: 525 / 821

On to step 3:
821 goes into 525 0 times with a remainder of 525.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 525 to get 525.
Include the next digit (8) from the dividend after 525, then repeat: 5258 / 821

Step 4:
When dividing 5258 by 821, we get 6 with a remainder of 332.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 4926 from 5258 to get 332.
Take the next digit (7) from the dividend and append it to 332, then repeat: 3327 / 821

Going ahead to step 5:
The number 821 fits into 3327 4 times, leaving a remainder of 43.
The next digit of our result is 4. 
Result so far: 64.0
Subtracting 3284 from 3327 leaves us with 43.
Bring next digit (3) of the dividend behind the 43 and repeat the process: 433 / 821

Going ahead to step 6:
433 divided by 821 is 0 with a remainder of 433.
The next digit of our result is 0. 
Result so far: 640.0
Subtracting 0 from 433 leaves us with 433.
Include the next digit (5) from the dividend after 433, then repeat: 4335 / 821

Going ahead to step 7:
821 goes into 4335 5 times with a remainder of 230.
Record the quotient 5 as the next digit in the result. 
Result so far: 6405.0
Subtracting 4105 from 4335 leaves us with 230.
Bring next digit (8) of the dividend behind the 230 and repeat the process: 2308 / 821

Let's proceed to step 8:
If we divide 2308 by 821, we get 2 and a remainder of 666.
The number 2 becomes the next digit in our result. 
Result so far: 64052.0
Subtract 1642 from 2308 to get 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Moving on to step 9:
The number 821 fits into 6660 8 times, leaving a remainder of 92.
Write down 8 as next digit of the result. 
Result so far: 64052.8
If we subtract 6568 from 6660, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 10:
If we divide 920 by 821, we get 1 and a remainder of 99.
The next digit of our result is 1. 
Result so far: 64052.81
Subtracting 821 from 920 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 11:
821 can be fit into 990 1 times, resulting in a remainder of 169.
Record the quotient 1 as the next digit in the result. 
Result so far: 64052.811
Subtracting 821 from 990 leaves us with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

The quotient of the division is 64052.811, and the remainder is 0.0169.
