We're dividing 821401 by 53 
Let's see how many times 53 fits into 821401.

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.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 53

Going ahead to step 2:
The number 53 fits into 82 1 times, leaving a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 53 from 82, we get 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 53

On to step 3:
The number 53 fits into 291 5 times, leaving a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 265 from 291 leaves us with 26.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 53

On to step 4:
The number 53 fits into 264 4 times, leaving a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 154.0
If we take 212 away from 264, we end up with 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 53

Going ahead to step 5:
If we divide 520 by 53, we get 9 and a remainder of 43.
The next digit of our result is 9. 
Result so far: 1549.0
The remainder is 43 after subtracting 477 from 520.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 53

Let's proceed to step 6:
53 goes into 431 8 times with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 15498.0
Deduct 424 from 431 and we're left 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.

Moving on to step 7:
53 goes into 70 1 times with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 15498.1
Subtracting 53 from 70 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 8:
53 can be fit into 170 3 times, resulting in a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 15498.13
Subtracting 159 from 170 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
53 goes into 110 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 15498.132
The remainder is 4 after subtracting 106 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
40 divided by 53 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 15498.132
Subtract 0 from 40 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.

Step 11:
The number 53 fits into 400 7 times, leaving a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 15498.13207
Deduct 371 from 400 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 12:
53 goes into 290 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 15498.132075
Subtract 265 from 290 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 13:
If we divide 250 by 53, we get 4 and a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 15498.1320754
If we subtract 212 from 250, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 14:
When dividing 380 by 53, we get 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 15498.13207547
Subtract 371 from 380 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 15498.13207547 with a balance of 9e-09.
