We divide 151819 by 81
Our goal is to divide 151819 by 81.

Advancing 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
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 81

Let's proceed to step 2:
When dividing 15 by 81, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 81

Moving on to step 3:
151 divided by 81 is 1 with a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 81 from 151, we get 70.
Bring next digit (8) of the dividend behind the 70 and repeat the process: 708 / 81

Advancing to step 4:
81 goes into 708 8 times with a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 648 from 708 leaves us with 60.
Include the next digit (1) from the dividend after 60, then repeat: 601 / 81

Advancing to step 5:
When dividing 601 by 81, we get 7 with a remainder of 34.
The next digit of our result is 7. 
Result so far: 187.0
The remainder is 34 after subtracting 567 from 601.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 81

Step 6:
81 goes into 349 4 times with a remainder of 25.
Use 4 as the next digit of our solution. 
Result so far: 1874.0
Subtract 324 from 349 to 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.

On to step 7:
The number 81 fits into 250 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 1874.3
The remainder is 7 after subtracting 243 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
The number 81 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 1874.3
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 9:
700 divided by 81 is 8 with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 1874.308
Deduct 648 from 700 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 10:
The number 81 fits into 520 6 times, leaving a remainder of 34.
The next digit of our result is 6. 
Result so far: 1874.3086
If we take 486 away from 520, we end up 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.

On to step 11:
81 goes into 340 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 1874.30864
Subtracting 324 from 340 leaves us with 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 12:
81 goes into 160 1 times with a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 1874.308641
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.

Going ahead to step 13:
When dividing 790 by 81, we get 9 with a remainder of 61.
The next digit of our result is 9. 
Result so far: 1874.3086419
If we take 729 away from 790, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 14:
If we divide 610 by 81, we get 7 and a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 1874.30864197
Deduct 567 from 610 and we're left 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.

The final outcome is 1874.30864197, with a leftover of 4.3e-08.
