We divide 170492 by 81
We want to divide 170492 by 81.

Step 1:
If we divide 1 by 81, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 81

Let's proceed to step 2:
17 divided by 81 is 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 81

Step 3:
The number 81 fits into 170 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 162 from 170 and we're left with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 81

On to step 4:
When dividing 84 by 81, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 81 away from 84, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 81

Advancing to step 5:
The number 81 fits into 39 0 times, leaving a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 210.0
Deduct 0 from 39 and we're left with 39.
Append the next digit (2) from the dividend to 39 and continue with: 392 / 81

On to step 6:
The number 81 fits into 392 4 times, leaving a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 2104.0
Subtracting 324 from 392 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 7:
When dividing 680 by 81, we get 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 2104.8
If we take 648 away from 680, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 8:
The number 81 fits into 320 3 times, leaving a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 2104.83
If we take 243 away from 320, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 9:
81 goes into 770 9 times with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 2104.839
If we take 729 away from 770, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 10:
If we divide 410 by 81, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 2104.8395
If we subtract 405 from 410, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
81 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 2104.8395
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
81 can be fit into 500 6 times, resulting in a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 2104.839506
Subtracting 486 from 500 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 13:
The number 81 fits into 140 1 times, leaving a remainder of 59.
The next digit of our result is 1. 
Result so far: 2104.8395061
If we take 81 away from 140, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 14:
When dividing 590 by 81, we get 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 2104.83950617
The remainder is 23 after subtracting 567 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 2104.83950617, with a leftover of 2.3e-08.
