Let's divide 81310981 by 542
We want to divide 81310981 by 542.

Going ahead to step 1:
542 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 542

Let's proceed to step 2:
542 can be fit into 81 0 times, resulting in a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Bring next digit (3) of the dividend behind the 81 and repeat the process: 813 / 542

Step 3:
542 can be fit into 813 1 times, resulting in a remainder of 271.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 542 away from 813, we end up with 271.
Include the next digit (1) from the dividend after 271, then repeat: 2711 / 542

Step 4:
If we divide 2711 by 542, we get 5 and a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 1 after subtracting 2710 from 2711.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 542

Advancing to step 5:
10 divided by 542 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
Subtracting 0 from 10 leaves us with 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 542

Going ahead to step 6:
If we divide 109 by 542, we get 0 and a remainder of 109.
The next digit of our result is 0. 
Result so far: 1500.0
Subtract 0 from 109 to get 109.
Take the next digit (8) from the dividend and append it to 109, then repeat: 1098 / 542

Advancing to step 7:
542 can be fit into 1098 2 times, resulting in a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 15002.0
If we subtract 1084 from 1098, we get 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 542

Step 8:
542 can be fit into 141 0 times, resulting in a remainder of 141.
Put 0 as the next digit of the answer. 
Result so far: 150020.0
If we subtract 0 from 141, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 9:
If we divide 1410 by 542, we get 2 and a remainder of 326.
Record the quotient 2 as the next digit in the result. 
Result so far: 150020.2
Subtract 1084 from 1410 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Moving on to step 10:
3260 divided by 542 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 150020.26
If we take 3252 away from 3260, we end up 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.

Going ahead to step 11:
If we divide 80 by 542, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 150020.26
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
800 divided by 542 is 1 with a remainder of 258.
Record the quotient 1 as the next digit in the result. 
Result so far: 150020.2601
If we take 542 away from 800, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Moving on to step 13:
2580 divided by 542 is 4 with a remainder of 412.
Use 4 as the next digit of our solution. 
Result so far: 150020.26014
The remainder is 412 after subtracting 2168 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Advancing to step 14:
The number 542 fits into 4120 7 times, leaving a remainder of 326.
The number 7 becomes the next digit in our result. 
Result so far: 150020.260147
Subtracting 3794 from 4120 leaves us with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Going ahead to step 15:
542 goes into 3260 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 150020.2601476
If we take 3252 away from 3260, we end up 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.

On to step 16:
If we divide 80 by 542, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 150020.2601476
Deduct 0 from 80 and we're left 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.

Our division results in 150020.2601476 with a remaining 8e-08.
