Let's divide 140453 by 81
Let's see how many times 81 fits into 140453.

On to step 1:
81 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 81

Moving on to step 2:
When dividing 14 by 81, we get 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 81

Moving on to step 3:
If we divide 140 by 81, we get 1 and a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 81 from 140 and we're left with 59.
Append the next digit (4) from the dividend to 59 and continue with: 594 / 81

Step 4:
If we divide 594 by 81, we get 7 and a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 27 after subtracting 567 from 594.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 81

Let's proceed to step 5:
If we divide 275 by 81, we get 3 and a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 173.0
Subtract 243 from 275 to get 32.
Append the next digit (3) from the dividend to 32 and continue with: 323 / 81

Step 6:
When dividing 323 by 81, we get 3 with a remainder of 80.
Use 3 as the next digit of our solution. 
Result so far: 1733.0
Subtracting 243 from 323 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 7:
800 divided by 81 is 9 with a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 1733.9
The remainder is 71 after subtracting 729 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 8:
When dividing 710 by 81, we get 8 with a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 1733.98
If we subtract 648 from 710, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 9:
The number 81 fits into 620 7 times, leaving a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 1733.987
Deduct 567 from 620 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 10:
If we divide 530 by 81, we get 6 and a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 1733.9876
Subtract 486 from 530 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
440 divided by 81 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 1733.98765
The remainder is 35 after subtracting 405 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
350 divided by 81 is 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 1733.987654
The remainder is 26 after subtracting 324 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
The number 81 fits into 260 3 times, leaving a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 1733.9876543
Subtract 243 from 260 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 14:
The number 81 fits into 170 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 1733.98765432
Deduct 162 from 170 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 1733.98765432 with a remaining 8e-09.
