19531469 ÷ 142 
We want to divide 19531469 by 142.

Step 1:
The number 142 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 142

Advancing to step 2:
142 can be fit into 19 0 times, resulting in a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 142

Let's proceed to step 3:
If we divide 195 by 142, we get 1 and a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 142 from 195, we get 53.
Append the next digit (3) from the dividend to 53 and continue with: 533 / 142

Let's proceed to step 4:
142 can be fit into 533 3 times, resulting in a remainder of 107.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 426 from 533 leaves us with 107.
Include the next digit (1) from the dividend after 107, then repeat: 1071 / 142

Advancing to step 5:
The number 142 fits into 1071 7 times, leaving a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 137.0
Subtract 994 from 1071 to get 77.
Include the next digit (4) from the dividend after 77, then repeat: 774 / 142

Let's proceed to step 6:
When dividing 774 by 142, we get 5 with a remainder of 64.
The next digit of our result is 5. 
Result so far: 1375.0
The remainder is 64 after subtracting 710 from 774.
Bring next digit (6) of the dividend behind the 64 and repeat the process: 646 / 142

On to step 7:
142 goes into 646 4 times with a remainder of 78.
Record the quotient 4 as the next digit in the result. 
Result so far: 13754.0
If we take 568 away from 646, we end up with 78.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 142

Let's proceed to step 8:
142 can be fit into 789 5 times, resulting in a remainder of 79.
Record the quotient 5 as the next digit in the result. 
Result so far: 137545.0
If we take 710 away from 789, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 9:
The number 142 fits into 790 5 times, leaving a remainder of 80.
The next digit of our result is 5. 
Result so far: 137545.5
The remainder is 80 after subtracting 710 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
142 goes into 800 5 times with a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 137545.55
Subtract 710 from 800 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final outcome is 137545.55, with a leftover of 0.09.
