52821877 ÷ 810 
Our goal is to divide 52821877 by 810.

Going ahead to step 1:
The number 810 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 810

Let's proceed to step 2:
When dividing 52 by 810, we get 0 with 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.
Include the next digit (8) from the dividend after 52, then repeat: 528 / 810

Step 3:
If we divide 528 by 810, we get 0 and a remainder of 528.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 528 after subtracting 0 from 528.
Append the next digit (2) from the dividend to 528 and continue with: 5282 / 810

Going ahead to step 4:
810 can be fit into 5282 6 times, resulting in a remainder of 422.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 4860 from 5282 and we're left with 422.
Take the next digit (1) from the dividend and append it to 422, then repeat: 4221 / 810

Let's proceed to step 5:
810 goes into 4221 5 times with a remainder of 171.
The next digit of our result is 5. 
Result so far: 65.0
If we take 4050 away from 4221, we end up with 171.
Append the next digit (8) from the dividend to 171 and continue with: 1718 / 810

Going ahead to step 6:
1718 divided by 810 is 2 with a remainder of 98.
Put 2 as the next digit of the answer. 
Result so far: 652.0
Subtracting 1620 from 1718 leaves us with 98.
Append the next digit (7) from the dividend to 98 and continue with: 987 / 810

Advancing to step 7:
If we divide 987 by 810, we get 1 and a remainder of 177.
Use 1 as the next digit of our solution. 
Result so far: 6521.0
If we take 810 away from 987, we end up with 177.
Include the next digit (7) from the dividend after 177, then repeat: 1777 / 810

Let's proceed to step 8:
810 goes into 1777 2 times with a remainder of 157.
Record the quotient 2 as the next digit in the result. 
Result so far: 65212.0
Deduct 1620 from 1777 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 9:
The number 810 fits into 1570 1 times, leaving a remainder of 760.
The next digit of our result is 1. 
Result so far: 65212.1
Deduct 810 from 1570 and we're left with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 10:
The number 810 fits into 7600 9 times, leaving a remainder of 310.
Write down 9 as next digit of the result. 
Result so far: 65212.19
The remainder is 310 after subtracting 7290 from 7600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 11:
810 can be fit into 3100 3 times, resulting in a remainder of 670.
Write down 3 as next digit of the result. 
Result so far: 65212.193
Deduct 2430 from 3100 and we're left with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

On to step 12:
810 can be fit into 6700 8 times, resulting in a remainder of 220.
Use 8 as the next digit of our solution. 
Result so far: 65212.1938
The remainder is 220 after subtracting 6480 from 6700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 13:
When dividing 2200 by 810, we get 2 with a remainder of 580.
The next digit of our result is 2. 
Result so far: 65212.19382
The remainder is 580 after subtracting 1620 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 14:
When dividing 5800 by 810, we get 7 with a remainder of 130.
Write down 7 as next digit of the result. 
Result so far: 65212.193827
The remainder is 130 after subtracting 5670 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 15:
810 goes into 1300 1 times with a remainder of 490.
The next digit of our result is 1. 
Result so far: 65212.1938271
Subtract 810 from 1300 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 16:
If we divide 4900 by 810, we get 6 and a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 65212.19382716
Subtract 4860 from 4900 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 65212.19382716, with a leftover of 4e-08.
