We're dividing 821395 by 53 
We're looking to find how many times 53 goes into 821395.

Step 1:
53 goes into 8 0 times with 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.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 53

Let's proceed to step 2:
If we divide 82 by 53, we get 1 and a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 53 from 82 to get 29.
Take the next digit (1) from the dividend and append it to 29, then repeat: 291 / 53

Step 3:
The number 53 fits into 291 5 times, leaving a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 265 from 291, we get 26.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 53

Moving on to step 4:
263 divided by 53 is 4 with a remainder of 51.
Write down 4 as next digit of the result. 
Result so far: 154.0
If we subtract 212 from 263, we get 51.
Include the next digit (9) from the dividend after 51, then repeat: 519 / 53

Going ahead to step 5:
519 divided by 53 is 9 with a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 1549.0
If we take 477 away from 519, we end up with 42.
Grab the next digit (5) from the dividend, add it to 42, then carry on: 425 / 53

Let's proceed to step 6:
425 divided by 53 is 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 15498.0
If we subtract 424 from 425, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
10 divided by 53 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 15498.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
100 divided by 53 is 1 with a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 15498.01
The remainder is 47 after subtracting 53 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 9:
When dividing 470 by 53, we get 8 with a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 15498.018
Deduct 424 from 470 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 10:
The number 53 fits into 460 8 times, leaving a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 15498.0188
If we subtract 424 from 460, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 15498.0188, with a leftover of 0.00036.
