We look at the division of 20390838 by 85 
We're looking to find how many times 85 goes into 20390838.

On to step 1:
When dividing 2 by 85, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 85

On to step 2:
The number 85 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 85

Moving on to step 3:
85 can be fit into 203 2 times, resulting in a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 170 from 203, we get 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 85

Step 4:
339 divided by 85 is 3 with a remainder of 84.
Put 3 as the next digit of the answer. 
Result so far: 23.0
The remainder is 84 after subtracting 255 from 339.
Include the next digit (0) from the dividend after 84, then repeat: 840 / 85

Going ahead to step 5:
85 goes into 840 9 times with a remainder of 75.
Write down 9 as next digit of the result. 
Result so far: 239.0
If we take 765 away from 840, we end up with 75.
Fetch the next digit (8) from the dividend, attach it to 75 and continue: 758 / 85

On to step 6:
758 divided by 85 is 8 with a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 2398.0
The remainder is 78 after subtracting 680 from 758.
Take the next digit (3) from the dividend and append it to 78, then repeat: 783 / 85

Advancing to step 7:
85 goes into 783 9 times with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 23989.0
If we take 765 away from 783, we end up with 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 85

Advancing to step 8:
85 can be fit into 188 2 times, resulting in a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 239892.0
Subtract 170 from 188 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.

Let's proceed to step 9:
When dividing 180 by 85, we get 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 239892.2
The remainder is 10 after subtracting 170 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
The number 85 fits into 100 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 239892.21
Subtract 85 from 100 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
The number 85 fits into 150 1 times, leaving a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 239892.211
If we take 85 away from 150, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final outcome is 239892.211, with a leftover of 0.0065.
