We're dividing 2021865 by 852 
Our goal is to divide 2021865 by 852.

Going ahead to step 1:
The number 852 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 852

Let's proceed to step 2:
20 divided by 852 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 852

On to step 3:
852 goes into 202 0 times with a remainder of 202.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 202 and we're left with 202.
Include the next digit (1) from the dividend after 202, then repeat: 2021 / 852

Let's proceed to step 4:
2021 divided by 852 is 2 with a remainder of 317.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1704 from 2021 and we're left with 317.
Take the next digit (8) from the dividend and append it to 317, then repeat: 3178 / 852

On to step 5:
When dividing 3178 by 852, we get 3 with a remainder of 622.
The next digit of our result is 3. 
Result so far: 23.0
If we subtract 2556 from 3178, we get 622.
Grab the next digit (6) from the dividend, add it to 622, then carry on: 6226 / 852

On to step 6:
852 can be fit into 6226 7 times, resulting in a remainder of 262.
The next digit of our result is 7. 
Result so far: 237.0
Subtract 5964 from 6226 to get 262.
Include the next digit (5) from the dividend after 262, then repeat: 2625 / 852

Going ahead to step 7:
852 goes into 2625 3 times with a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 2373.0
Deduct 2556 from 2625 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 8:
690 divided by 852 is 0 with a remainder of 690.
Record the quotient 0 as the next digit in the result. 
Result so far: 2373.0
If we subtract 0 from 690, we get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Let's proceed to step 9:
If we divide 6900 by 852, we get 8 and a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 2373.08
Subtracting 6816 from 6900 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 10:
852 goes into 840 0 times with a remainder of 840.
Use 0 as the next digit of our solution. 
Result so far: 2373.08
The remainder is 840 after subtracting 0 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Advancing to step 11:
852 can be fit into 8400 9 times, resulting in a remainder of 732.
Put 9 as the next digit of the answer. 
Result so far: 2373.0809
If we subtract 7668 from 8400, we get 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Going ahead to step 12:
The number 852 fits into 7320 8 times, leaving a remainder of 504.
Record the quotient 8 as the next digit in the result. 
Result so far: 2373.08098
Subtract 6816 from 7320 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Moving on to step 13:
852 can be fit into 5040 5 times, resulting in a remainder of 780.
The next digit of our result is 5. 
Result so far: 2373.080985
Deduct 4260 from 5040 and we're left with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Step 14:
The number 852 fits into 7800 9 times, leaving a remainder of 132.
Use 9 as the next digit of our solution. 
Result so far: 2373.0809859
If we subtract 7668 from 7800, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 15:
852 goes into 1320 1 times with a remainder of 468.
The number 1 becomes the next digit in our result. 
Result so far: 2373.08098591
Subtracting 852 from 1320 leaves us with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

The final result is 2373.08098591 with a remainder of 4.68e-07.
