Let's divide 600021 by 53
We're looking to find how many times 53 goes into 600021.

Advancing to step 1:
When dividing 6 by 53, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 53

Moving on to step 2:
60 divided by 53 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 53 from 60 leaves us with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 53

Going ahead to step 3:
53 can be fit into 70 1 times, resulting in a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 17 after subtracting 53 from 70.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 53

Step 4:
When dividing 170 by 53, we get 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
Deduct 159 from 170 and we're left with 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 53

Let's proceed to step 5:
112 divided by 53 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 1132.0
Subtracting 106 from 112 leaves us with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 53

Advancing to step 6:
53 can be fit into 61 1 times, resulting in a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 11321.0
Subtract 53 from 61 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
When dividing 80 by 53, we get 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 11321.1
Subtracting 53 from 80 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 8:
If we divide 270 by 53, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 11321.15
Subtracting 265 from 270 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
50 divided by 53 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 11321.15
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
If we divide 500 by 53, we get 9 and a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 11321.1509
The remainder is 23 after subtracting 477 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 11:
230 divided by 53 is 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 11321.15094
Subtract 212 from 230 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
The number 53 fits into 180 3 times, leaving a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 11321.150943
If we take 159 away from 180, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 13:
If we divide 210 by 53, we get 3 and a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 11321.1509433
If we take 159 away from 210, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final result is 11321.1509433 with a remainder of 5.1e-07.
