We look at the division of 20422019 by 852 
Let's see how many times 852 fits into 20422019.

Advancing to step 1:
The number 852 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 852

Let's proceed to step 2:
The number 852 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 852

Let's proceed to step 3:
The number 852 fits into 204 0 times, leaving a remainder of 204.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 204 leaves us with 204.
Include the next digit (2) from the dividend after 204, then repeat: 2042 / 852

Moving on to step 4:
When dividing 2042 by 852, we get 2 with a remainder of 338.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1704 from 2042 leaves us with 338.
Bring next digit (2) of the dividend behind the 338 and repeat the process: 3382 / 852

On to step 5:
If we divide 3382 by 852, we get 3 and a remainder of 826.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Deduct 2556 from 3382 and we're left with 826.
Grab the next digit (0) from the dividend, add it to 826, then carry on: 8260 / 852

Step 6:
8260 divided by 852 is 9 with a remainder of 592.
Record the quotient 9 as the next digit in the result. 
Result so far: 239.0
If we subtract 7668 from 8260, we get 592.
Bring next digit (1) of the dividend behind the 592 and repeat the process: 5921 / 852

Going ahead to step 7:
The number 852 fits into 5921 6 times, leaving a remainder of 809.
Write down 6 as next digit of the result. 
Result so far: 2396.0
If we subtract 5112 from 5921, we get 809.
Append the next digit (9) from the dividend to 809 and continue with: 8099 / 852

Going ahead to step 8:
If we divide 8099 by 852, we get 9 and a remainder of 431.
Put 9 as the next digit of the answer. 
Result so far: 23969.0
If we take 7668 away from 8099, we end up with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Let's proceed to step 9:
If we divide 4310 by 852, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 23969.5
The remainder is 50 after subtracting 4260 from 4310.
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:
The number 852 fits into 500 0 times, leaving a remainder of 500.
The next digit of our result is 0. 
Result so far: 23969.5
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 11:
852 can be fit into 5000 5 times, resulting in a remainder of 740.
Record the quotient 5 as the next digit in the result. 
Result so far: 23969.505
If we subtract 4260 from 5000, we get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Advancing to step 12:
The number 852 fits into 7400 8 times, leaving a remainder of 584.
Put 8 as the next digit of the answer. 
Result so far: 23969.5058
Subtracting 6816 from 7400 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Moving on to step 13:
5840 divided by 852 is 6 with a remainder of 728.
The number 6 becomes the next digit in our result. 
Result so far: 23969.50586
Deduct 5112 from 5840 and we're left with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Step 14:
The number 852 fits into 7280 8 times, leaving a remainder of 464.
The number 8 becomes the next digit in our result. 
Result so far: 23969.505868
The remainder is 464 after subtracting 6816 from 7280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 15:
If we divide 4640 by 852, we get 5 and a remainder of 380.
The next digit of our result is 5. 
Result so far: 23969.5058685
Subtracting 4260 from 4640 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 16:
If we divide 3800 by 852, we get 4 and a remainder of 392.
The number 4 becomes the next digit in our result. 
Result so far: 23969.50586854
Deduct 3408 from 3800 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

The final outcome is 23969.50586854, with a leftover of 3.92e-07.
