We look at the division of 866851 by 53 
We want to divide 866851 by 53.

Moving on to step 1:
If we divide 8 by 53, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 53

Step 2:
When dividing 86 by 53, we get 1 with a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 53 from 86 and we're left with 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 53

Going ahead to step 3:
336 divided by 53 is 6 with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 318 from 336, we get 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 53

Advancing to step 4:
53 can be fit into 188 3 times, resulting in a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 163.0
Subtract 159 from 188 to get 29.
Append the next digit (5) from the dividend to 29 and continue with: 295 / 53

Advancing to step 5:
If we divide 295 by 53, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 1635.0
Subtract 265 from 295 to get 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 53

Advancing to step 6:
If we divide 301 by 53, we get 5 and a remainder of 36.
The number 5 becomes the next digit in our result. 
Result so far: 16355.0
If we take 265 away from 301, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
When dividing 360 by 53, we get 6 with a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 16355.6
If we subtract 318 from 360, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
When dividing 420 by 53, we get 7 with a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 16355.67
Subtract 371 from 420 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
If we divide 490 by 53, we get 9 and a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 16355.679
Subtract 477 from 490 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 10:
When dividing 130 by 53, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 16355.6792
The remainder is 24 after subtracting 106 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
If we divide 240 by 53, we get 4 and a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 16355.67924
If we take 212 away from 240, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 12:
53 goes into 280 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 16355.679245
The remainder is 15 after subtracting 265 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
53 can be fit into 150 2 times, resulting in a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 16355.6792452
If we subtract 106 from 150, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 14:
The number 53 fits into 440 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 16355.67924528
The remainder is 16 after subtracting 424 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 16355.67924528 with a remainder of 1.6e-08.
