80210677 ÷ 142 
We're looking to find how many times 142 goes into 80210677.

Step 1:
When dividing 8 by 142, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 142

On to step 2:
142 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Grab the next digit (2) from the dividend, add it to 80, then carry on: 802 / 142

On to step 3:
142 can be fit into 802 5 times, resulting in a remainder of 92.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 710 from 802 and we're left with 92.
Grab the next digit (1) from the dividend, add it to 92, then carry on: 921 / 142

Let's proceed to step 4:
142 goes into 921 6 times with a remainder of 69.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
If we take 852 away from 921, we end up with 69.
Append the next digit (0) from the dividend to 69 and continue with: 690 / 142

Advancing to step 5:
If we divide 690 by 142, we get 4 and a remainder of 122.
The number 4 becomes the next digit in our result. 
Result so far: 564.0
Deduct 568 from 690 and we're left with 122.
Fetch the next digit (6) from the dividend, attach it to 122 and continue: 1226 / 142

On to step 6:
142 can be fit into 1226 8 times, resulting in a remainder of 90.
Write down 8 as next digit of the result. 
Result so far: 5648.0
The remainder is 90 after subtracting 1136 from 1226.
Take the next digit (7) from the dividend and append it to 90, then repeat: 907 / 142

Going ahead to step 7:
The number 142 fits into 907 6 times, leaving a remainder of 55.
The next digit of our result is 6. 
Result so far: 56486.0
The remainder is 55 after subtracting 852 from 907.
Append the next digit (7) from the dividend to 55 and continue with: 557 / 142

Moving on to step 8:
142 can be fit into 557 3 times, resulting in a remainder of 131.
The number 3 becomes the next digit in our result. 
Result so far: 564863.0
Subtract 426 from 557 to get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

On to step 9:
If we divide 1310 by 142, we get 9 and a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 564863.9
If we take 1278 away from 1310, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
When dividing 320 by 142, we get 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 564863.92
Subtract 284 from 320 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
360 divided by 142 is 2 with a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 564863.922
If we subtract 284 from 360, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 564863.922 and a remainder of 0.0076.
