18997579 ÷ 142 
Our goal is to divide 18997579 by 142.

Step 1:
142 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 142

Step 2:
The number 142 fits into 18 0 times, leaving a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 142

On to step 3:
When dividing 189 by 142, we get 1 with a remainder of 47.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 47 after subtracting 142 from 189.
Append the next digit (9) from the dividend to 47 and continue with: 479 / 142

On to step 4:
When dividing 479 by 142, we get 3 with a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 426 away from 479, we end up with 53.
Fetch the next digit (7) from the dividend, attach it to 53 and continue: 537 / 142

On to step 5:
If we divide 537 by 142, we get 3 and a remainder of 111.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
Deduct 426 from 537 and we're left with 111.
Include the next digit (5) from the dividend after 111, then repeat: 1115 / 142

On to step 6:
When dividing 1115 by 142, we get 7 with a remainder of 121.
Use 7 as the next digit of our solution. 
Result so far: 1337.0
If we take 994 away from 1115, we end up with 121.
Bring next digit (7) of the dividend behind the 121 and repeat the process: 1217 / 142

Let's proceed to step 7:
142 can be fit into 1217 8 times, resulting in a remainder of 81.
The number 8 becomes the next digit in our result. 
Result so far: 13378.0
Deduct 1136 from 1217 and we're left with 81.
Include the next digit (9) from the dividend after 81, then repeat: 819 / 142

Let's proceed to step 8:
If we divide 819 by 142, we get 5 and a remainder of 109.
The next digit of our result is 5. 
Result so far: 133785.0
If we subtract 710 from 819, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 9:
142 can be fit into 1090 7 times, resulting in a remainder of 96.
The number 7 becomes the next digit in our result. 
Result so far: 133785.7
Deduct 994 from 1090 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 10:
The number 142 fits into 960 6 times, leaving a remainder of 108.
The next digit of our result is 6. 
Result so far: 133785.76
Subtracting 852 from 960 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 11:
1080 divided by 142 is 7 with a remainder of 86.
The number 7 becomes the next digit in our result. 
Result so far: 133785.767
The remainder is 86 after subtracting 994 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 12:
142 can be fit into 860 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 133785.7676
If we subtract 852 from 860, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
80 divided by 142 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 133785.7676
Subtract 0 from 80 to 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.

Step 14:
When dividing 800 by 142, we get 5 with a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 133785.767605
Deduct 710 from 800 and we're left 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 15:
142 can be fit into 900 6 times, resulting in a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 133785.7676056
If we take 852 away from 900, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 16:
When dividing 480 by 142, we get 3 with a remainder of 54.
Record the quotient 3 as the next digit in the result. 
Result so far: 133785.76760563
If we subtract 426 from 480, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 133785.76760563 with a remainder of 5.4e-08.
