We look at the division of 620243 by 53 
Let's see how many times 53 fits into 620243.

On to step 1:
When dividing 6 by 53, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 53

Step 2:
When dividing 62 by 53, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 53 from 62 to get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 53

Going ahead to step 3:
The number 53 fits into 90 1 times, leaving a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 53 from 90 leaves us with 37.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 53

Step 4:
372 divided by 53 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 117.0
If we take 371 away from 372, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 53

Moving on to step 5:
When dividing 14 by 53, we get 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 1170.0
If we subtract 0 from 14, we get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 53

Let's proceed to step 6:
53 goes into 143 2 times with a remainder of 37.
Record the quotient 2 as the next digit in the result. 
Result so far: 11702.0
Subtract 106 from 143 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 7:
When dividing 370 by 53, we get 6 with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 11702.6
The remainder is 52 after subtracting 318 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 8:
520 divided by 53 is 9 with a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 11702.69
If we take 477 away from 520, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 9:
53 goes into 430 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 11702.698
Subtracting 424 from 430 leaves us 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.

Going ahead to step 10:
When dividing 60 by 53, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 11702.6981
The remainder is 7 after subtracting 53 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 11:
If we divide 70 by 53, we get 1 and a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 11702.69811
If we take 53 away from 70, we end up 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.

The quotient of the division is 11702.69811, and the remainder is 1.7e-05.
