We look at the division of 156199 by 81 
We want to divide 156199 by 81.

On to step 1:
81 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 81

Going ahead to step 2:
If we divide 15 by 81, we get 0 and a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 81

Moving on to step 3:
81 can be fit into 156 1 times, resulting in a remainder of 75.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 81 away from 156, we end up with 75.
Append the next digit (1) from the dividend to 75 and continue with: 751 / 81

Moving on to step 4:
81 can be fit into 751 9 times, resulting in a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 22 after subtracting 729 from 751.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 81

Let's proceed to step 5:
229 divided by 81 is 2 with a remainder of 67.
The number 2 becomes the next digit in our result. 
Result so far: 192.0
Subtracting 162 from 229 leaves us with 67.
Bring next digit (9) of the dividend behind the 67 and repeat the process: 679 / 81

Let's proceed to step 6:
When dividing 679 by 81, we get 8 with a remainder of 31.
Put 8 as the next digit of the answer. 
Result so far: 1928.0
Deduct 648 from 679 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
81 goes into 310 3 times with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 1928.3
If we subtract 243 from 310, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 8:
81 goes into 670 8 times with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 1928.38
If we take 648 away from 670, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
When dividing 220 by 81, we get 2 with a remainder of 58.
The next digit of our result is 2. 
Result so far: 1928.382
Subtract 162 from 220 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
When dividing 580 by 81, we get 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 1928.3827
The remainder is 13 after subtracting 567 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
130 divided by 81 is 1 with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 1928.38271
Subtract 81 from 130 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 12:
If we divide 490 by 81, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 1928.382716
Subtracting 486 from 490 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
If we divide 40 by 81, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 1928.382716
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
81 goes into 400 4 times with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 1928.38271604
Deduct 324 from 400 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 1928.38271604 with a remainder of 7.6e-08.
