878209 ÷ 53 
We want to figure out the number of times 878209 can be divided by 53.

Let's proceed to step 1:
The number 53 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
Deduct 0 from 8 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 53

Advancing to step 2:
53 can be fit into 87 1 times, resulting in a remainder of 34.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 34 after subtracting 53 from 87.
Include the next digit (8) from the dividend after 34, then repeat: 348 / 53

Going ahead to step 3:
53 can be fit into 348 6 times, resulting in a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we take 318 away from 348, we end up with 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 53

Going ahead to step 4:
If we divide 302 by 53, we get 5 and a remainder of 37.
Put 5 as the next digit of the answer. 
Result so far: 165.0
The remainder is 37 after subtracting 265 from 302.
Include the next digit (0) from the dividend after 37, then repeat: 370 / 53

On to step 5:
53 goes into 370 6 times with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 1656.0
The remainder is 52 after subtracting 318 from 370.
Include the next digit (9) from the dividend after 52, then repeat: 529 / 53

Going ahead to step 6:
53 can be fit into 529 9 times, resulting in a remainder of 52.
Write down 9 as next digit of the result. 
Result so far: 16569.0
Subtracting 477 from 529 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 7:
The number 53 fits into 520 9 times, leaving a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 16569.9
Subtract 477 from 520 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 8:
When dividing 430 by 53, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 16569.98
If we take 424 away from 430, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
53 goes into 60 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 16569.981
If we take 53 away from 60, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
53 can be fit into 70 1 times, resulting in a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 16569.9811
If we subtract 53 from 70, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

In conclusion, the division gives 16569.9811 with a balance of 0.00017.
