We divide 155806 by 81
We're looking to find how many times 81 goes into 155806.

Step 1:
The number 81 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 81

Going ahead to step 2:
81 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 81

Going ahead to step 3:
81 goes into 155 1 times with a remainder of 74.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 81 from 155 to get 74.
Append the next digit (8) from the dividend to 74 and continue with: 748 / 81

On to step 4:
81 can be fit into 748 9 times, resulting in a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 729 from 748 leaves us with 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 81

Going ahead to step 5:
When dividing 190 by 81, we get 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 192.0
The remainder is 28 after subtracting 162 from 190.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 81

Let's proceed to step 6:
The number 81 fits into 286 3 times, leaving a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 1923.0
Subtracting 243 from 286 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 7:
When dividing 430 by 81, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 1923.5
If we subtract 405 from 430, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
If we divide 250 by 81, we get 3 and a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 1923.53
If we take 243 away from 250, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
81 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 1923.53
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
When dividing 700 by 81, we get 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 1923.5308
The remainder is 52 after subtracting 648 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
81 can be fit into 520 6 times, resulting in a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 1923.53086
Deduct 486 from 520 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 12:
81 can be fit into 340 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 1923.530864
If we subtract 324 from 340, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
160 divided by 81 is 1 with a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 1923.5308641
The remainder is 79 after subtracting 81 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 14:
790 divided by 81 is 9 with a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 1923.53086419
The remainder is 61 after subtracting 729 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Our division results in 1923.53086419 with a remaining 6.1e-08.
