We look at the division of 80887818 by 542 
We're looking to find how many times 542 goes into 80887818.

On to step 1:
When dividing 8 by 542, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 542

Moving on to step 2:
542 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Grab the next digit (8) from the dividend, add it to 80, then carry on: 808 / 542

Step 3:
If we divide 808 by 542, we get 1 and a remainder of 266.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 542 from 808 to get 266.
Take the next digit (8) from the dividend and append it to 266, then repeat: 2668 / 542

On to step 4:
2668 divided by 542 is 4 with a remainder of 500.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 2168 from 2668 to get 500.
Take the next digit (7) from the dividend and append it to 500, then repeat: 5007 / 542

On to step 5:
When dividing 5007 by 542, we get 9 with a remainder of 129.
Put 9 as the next digit of the answer. 
Result so far: 149.0
Subtracting 4878 from 5007 leaves us with 129.
Fetch the next digit (8) from the dividend, attach it to 129 and continue: 1298 / 542

Moving on to step 6:
1298 divided by 542 is 2 with a remainder of 214.
The number 2 becomes the next digit in our result. 
Result so far: 1492.0
If we subtract 1084 from 1298, we get 214.
Include the next digit (1) from the dividend after 214, then repeat: 2141 / 542

Moving on to step 7:
542 goes into 2141 3 times with a remainder of 515.
The next digit of our result is 3. 
Result so far: 14923.0
If we subtract 1626 from 2141, we get 515.
Take the next digit (8) from the dividend and append it to 515, then repeat: 5158 / 542

On to step 8:
5158 divided by 542 is 9 with a remainder of 280.
Record the quotient 9 as the next digit in the result. 
Result so far: 149239.0
If we subtract 4878 from 5158, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 9:
If we divide 2800 by 542, we get 5 and a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 149239.5
If we take 2710 away from 2800, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 10:
900 divided by 542 is 1 with a remainder of 358.
Use 1 as the next digit of our solution. 
Result so far: 149239.51
Subtracting 542 from 900 leaves us with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

On to step 11:
When dividing 3580 by 542, we get 6 with a remainder of 328.
The number 6 becomes the next digit in our result. 
Result so far: 149239.516
If we subtract 3252 from 3580, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 12:
The number 542 fits into 3280 6 times, leaving a remainder of 28.
The next digit of our result is 6. 
Result so far: 149239.5166
Deduct 3252 from 3280 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 149239.5166 and a remainder of 0.00028.
