Let's divide 20992 by 86
We're looking to find how many times 86 goes into 20992.

Going ahead to step 1:
2 divided by 86 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 86

Moving on to step 2:
The number 86 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 86

Moving on to step 3:
86 goes into 209 2 times with a remainder of 37.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 172 from 209 and we're left with 37.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 86

On to step 4:
86 goes into 379 4 times with a remainder of 35.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Deduct 344 from 379 and we're left with 35.
Fetch the next digit (2) from the dividend, attach it to 35 and continue: 352 / 86

Moving on to step 5:
352 divided by 86 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 244.0
If we take 344 away from 352, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 6:
80 divided by 86 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 244.0
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 7:
86 goes into 800 9 times with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 244.09
Subtract 774 from 800 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
86 goes into 260 3 times with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 244.093
Subtract 258 from 260 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
When dividing 20 by 86, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 244.093
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
86 can be fit into 200 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 244.09302
Subtracting 172 from 200 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
If we divide 280 by 86, we get 3 and a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 244.093023
The remainder is 22 after subtracting 258 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 12:
86 goes into 220 2 times with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 244.0930232
Subtract 172 from 220 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 13:
86 can be fit into 480 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 244.09302325
Subtract 430 from 480 to 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.

After the division, we end up with 244.09302325 and a remainder of 5e-08.
