We're dividing 18937121 by 142 
Let's see how many times 142 fits into 18937121.

Moving on to step 1:
142 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 142

Advancing to step 2:
142 can be fit into 18 0 times, resulting in a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 142

Advancing to step 3:
142 goes into 189 1 times with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 142 from 189 to get 47.
Take the next digit (3) from the dividend and append it to 47, then repeat: 473 / 142

Let's proceed to step 4:
473 divided by 142 is 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 426 from 473 leaves us with 47.
Grab the next digit (7) from the dividend, add it to 47, then carry on: 477 / 142

Moving on to step 5:
If we divide 477 by 142, we get 3 and a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 133.0
If we subtract 426 from 477, we get 51.
Bring next digit (1) of the dividend behind the 51 and repeat the process: 511 / 142

Advancing to step 6:
The number 142 fits into 511 3 times, leaving a remainder of 85.
Use 3 as the next digit of our solution. 
Result so far: 1333.0
Subtract 426 from 511 to get 85.
Append the next digit (2) from the dividend to 85 and continue with: 852 / 142

On to step 7:
The number 142 fits into 852 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 13336.0
Subtract 852 from 852 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 142

Moving on to step 8:
1 divided by 142 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 133360.0
Deduct 0 from 1 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
When dividing 10 by 142, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 133360.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
142 can be fit into 100 0 times, resulting in a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 133360.0
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 133360.0 and a remainder of 0.1.
