173874 ÷ 81 
We want to divide 173874 by 81.

Step 1:
81 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 81

Moving on to step 2:
If we divide 17 by 81, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 81

Let's proceed to step 3:
The number 81 fits into 173 2 times, leaving a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 162 from 173, we get 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 81

Let's proceed to step 4:
81 can be fit into 118 1 times, resulting in a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 81 from 118 to get 37.
Bring next digit (7) of the dividend behind the 37 and repeat the process: 377 / 81

Advancing to step 5:
81 goes into 377 4 times with a remainder of 53.
The number 4 becomes the next digit in our result. 
Result so far: 214.0
If we subtract 324 from 377, we get 53.
Fetch the next digit (4) from the dividend, attach it to 53 and continue: 534 / 81

Advancing to step 6:
When dividing 534 by 81, we get 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 2146.0
The remainder is 48 after subtracting 486 from 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 7:
81 can be fit into 480 5 times, resulting in a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 2146.5
Deduct 405 from 480 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 8:
750 divided by 81 is 9 with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 2146.59
Deduct 729 from 750 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 9:
When dividing 210 by 81, we get 2 with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 2146.592
The remainder is 48 after subtracting 162 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
81 can be fit into 480 5 times, resulting in a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 2146.5925
Subtract 405 from 480 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 11:
750 divided by 81 is 9 with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 2146.59259
The remainder is 21 after subtracting 729 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 12:
81 can be fit into 210 2 times, resulting in a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 2146.592592
The remainder is 48 after subtracting 162 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
If we divide 480 by 81, we get 5 and a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 2146.5925925
Deduct 405 from 480 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 14:
The number 81 fits into 750 9 times, leaving a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 2146.59259259
Subtract 729 from 750 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The quotient of the division is 2146.59259259, and the remainder is 2.1e-08.
