Let's divide 142265 by 81
Let's see how many times 81 fits into 142265.

Going ahead to step 1:
The number 81 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 81

Moving on to step 2:
14 divided by 81 is 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 81

Let's proceed to step 3:
81 can be fit into 142 1 times, resulting in a remainder of 61.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 81 from 142 and we're left with 61.
Append the next digit (2) from the dividend to 61 and continue with: 612 / 81

Going ahead to step 4:
When dividing 612 by 81, we get 7 with a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 45 after subtracting 567 from 612.
Append the next digit (6) from the dividend to 45 and continue with: 456 / 81

Going ahead to step 5:
When dividing 456 by 81, we get 5 with a remainder of 51.
Record the quotient 5 as the next digit in the result. 
Result so far: 175.0
The remainder is 51 after subtracting 405 from 456.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 81

Moving on to step 6:
81 can be fit into 515 6 times, resulting in a remainder of 29.
Put 6 as the next digit of the answer. 
Result so far: 1756.0
Subtract 486 from 515 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
When dividing 290 by 81, we get 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 1756.3
If we subtract 243 from 290, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 8:
81 can be fit into 470 5 times, resulting in a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 1756.35
If we take 405 away from 470, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 9:
The number 81 fits into 650 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 1756.358
If we take 648 away from 650, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
If we divide 20 by 81, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1756.358
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
81 goes into 200 2 times with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 1756.35802
If we take 162 away from 200, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
81 can be fit into 380 4 times, resulting in a remainder of 56.
The next digit of our result is 4. 
Result so far: 1756.358024
Subtract 324 from 380 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 13:
The number 81 fits into 560 6 times, leaving a remainder of 74.
The next digit of our result is 6. 
Result so far: 1756.3580246
If we take 486 away from 560, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 14:
740 divided by 81 is 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 1756.35802469
Subtract 729 from 740 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 1756.35802469 with a remaining 1.1e-08.
