20911596 ÷ 85 
We want to divide 20911596 by 85.

Let's proceed to step 1:
2 divided by 85 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 85

Let's proceed to step 2:
85 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 85

Advancing to step 3:
85 can be fit into 209 2 times, resulting in a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 170 from 209 to get 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 85

Moving on to step 4:
85 can be fit into 391 4 times, resulting in a remainder of 51.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Deduct 340 from 391 and we're left with 51.
Take the next digit (1) from the dividend and append it to 51, then repeat: 511 / 85

On to step 5:
511 divided by 85 is 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 246.0
The remainder is 1 after subtracting 510 from 511.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 85

Step 6:
85 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 2460.0
If we subtract 0 from 15, we get 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 85

Going ahead to step 7:
85 goes into 159 1 times with a remainder of 74.
Put 1 as the next digit of the answer. 
Result so far: 24601.0
If we take 85 away from 159, we end up with 74.
Grab the next digit (6) from the dividend, add it to 74, then carry on: 746 / 85

Step 8:
746 divided by 85 is 8 with a remainder of 66.
The next digit of our result is 8. 
Result so far: 246018.0
Subtract 680 from 746 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 9:
When dividing 660 by 85, we get 7 with a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 246018.7
If we subtract 595 from 660, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 10:
If we divide 650 by 85, we get 7 and a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 246018.77
The remainder is 55 after subtracting 595 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final outcome is 246018.77, with a leftover of 0.055.
