Let's divide 151723 by 81
We want to figure out the number of times 151723 can be divided by 81.

Advancing to step 1:
1 divided by 81 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 81

Moving on to step 2:
The number 81 fits into 15 0 times, leaving a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 81

Let's proceed to step 3:
81 goes into 151 1 times with a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 81 from 151 to get 70.
Take the next digit (7) from the dividend and append it to 70, then repeat: 707 / 81

Advancing to step 4:
81 can be fit into 707 8 times, resulting in a remainder of 59.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 648 from 707 and we're left with 59.
Append the next digit (2) from the dividend to 59 and continue with: 592 / 81

Advancing to step 5:
81 goes into 592 7 times with a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 187.0
If we subtract 567 from 592, we get 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 81

On to step 6:
81 can be fit into 253 3 times, resulting in a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 1873.0
If we take 243 away from 253, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
If we divide 100 by 81, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1873.1
If we subtract 81 from 100, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 8:
When dividing 190 by 81, we get 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 1873.12
The remainder is 28 after subtracting 162 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
280 divided by 81 is 3 with a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 1873.123
Subtracting 243 from 280 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 10:
81 goes into 370 4 times with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 1873.1234
Deduct 324 from 370 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 11:
The number 81 fits into 460 5 times, leaving a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 1873.12345
Deduct 405 from 460 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 12:
81 goes into 550 6 times with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 1873.123456
The remainder is 64 after subtracting 486 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
81 goes into 640 7 times with a remainder of 73.
The next digit of our result is 7. 
Result so far: 1873.1234567
The remainder is 73 after subtracting 567 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 14:
81 goes into 730 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 1873.12345679
The remainder is 1 after subtracting 729 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 1873.12345679 with a remainder of 1e-09.
