31373 divided by 81 
Our goal is to divide 31373 by 81.

Let's proceed to step 1:
The number 81 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 81

Moving on to step 2:
The number 81 fits into 31 0 times, leaving a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Bring next digit (3) of the dividend behind the 31 and repeat the process: 313 / 81

Going ahead to step 3:
If we divide 313 by 81, we get 3 and a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 243 from 313 and we're left with 70.
Take the next digit (7) from the dividend and append it to 70, then repeat: 707 / 81

Moving on to step 4:
81 goes into 707 8 times with a remainder of 59.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we take 648 away from 707, we end up with 59.
Take the next digit (3) from the dividend and append it to 59, then repeat: 593 / 81

Step 5:
81 goes into 593 7 times with a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 387.0
Deduct 567 from 593 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 6:
The number 81 fits into 260 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 387.3
If we subtract 243 from 260, we 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.

Moving on to step 7:
81 goes into 170 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 387.32
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
81 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 387.32
If we take 0 away from 80, we end up 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.

Step 9:
81 can be fit into 800 9 times, resulting in a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 387.3209
Subtracting 729 from 800 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 10:
710 divided by 81 is 8 with a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 387.32098
Subtract 648 from 710 to 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.

Advancing to step 11:
When dividing 620 by 81, we get 7 with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 387.320987
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.

On to step 12:
81 can be fit into 530 6 times, resulting in a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 387.3209876
If we take 486 away from 530, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 13:
When dividing 440 by 81, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 387.32098765
Deduct 405 from 440 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 387.32098765, and the remainder is 3.5e-08.
