We're dividing 66510113 by 142 
We want to divide 66510113 by 142.

On to step 1:
6 divided by 142 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 142

Let's proceed to step 2:
If we divide 66 by 142, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Include the next digit (5) from the dividend after 66, then repeat: 665 / 142

Moving on to step 3:
The number 142 fits into 665 4 times, leaving a remainder of 97.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 568 from 665, we get 97.
Append the next digit (1) from the dividend to 97 and continue with: 971 / 142

Advancing to step 4:
The number 142 fits into 971 6 times, leaving a remainder of 119.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Subtracting 852 from 971 leaves us with 119.
Append the next digit (0) from the dividend to 119 and continue with: 1190 / 142

Advancing to step 5:
The number 142 fits into 1190 8 times, leaving a remainder of 54.
The next digit of our result is 8. 
Result so far: 468.0
Subtracting 1136 from 1190 leaves us with 54.
Bring next digit (1) of the dividend behind the 54 and repeat the process: 541 / 142

Going ahead to step 6:
When dividing 541 by 142, we get 3 with a remainder of 115.
The number 3 becomes the next digit in our result. 
Result so far: 4683.0
Subtracting 426 from 541 leaves us with 115.
Grab the next digit (1) from the dividend, add it to 115, then carry on: 1151 / 142

Going ahead to step 7:
142 can be fit into 1151 8 times, resulting in a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 46838.0
If we take 1136 away from 1151, we end up with 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 142

Going ahead to step 8:
If we divide 153 by 142, we get 1 and a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 468381.0
Subtract 142 from 153 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
If we divide 110 by 142, we get 0 and a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 468381.0
If we subtract 0 from 110, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 10:
When dividing 1100 by 142, we get 7 with a remainder of 106.
The number 7 becomes the next digit in our result. 
Result so far: 468381.07
If we subtract 994 from 1100, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 11:
1060 divided by 142 is 7 with a remainder of 66.
The next digit of our result is 7. 
Result so far: 468381.077
The remainder is 66 after subtracting 994 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

In conclusion, the division gives 468381.077 with a balance of 0.0066.
