72193510 divided by 142 
We want to figure out the number of times 72193510 can be divided by 142.

On to step 1:
142 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 142

Let's proceed to step 2:
If we divide 72 by 142, we get 0 and a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Take the next digit (1) from the dividend and append it to 72, then repeat: 721 / 142

Advancing to step 3:
The number 142 fits into 721 5 times, leaving a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 710 from 721 leaves us with 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 142

Let's proceed to step 4:
If we divide 119 by 142, we get 0 and a remainder of 119.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Deduct 0 from 119 and we're left with 119.
Fetch the next digit (3) from the dividend, attach it to 119 and continue: 1193 / 142

Going ahead to step 5:
The number 142 fits into 1193 8 times, leaving a remainder of 57.
The next digit of our result is 8. 
Result so far: 508.0
Subtracting 1136 from 1193 leaves us with 57.
Take the next digit (5) from the dividend and append it to 57, then repeat: 575 / 142

Step 6:
575 divided by 142 is 4 with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 5084.0
Deduct 568 from 575 and we're left with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 142

Advancing to step 7:
142 can be fit into 71 0 times, resulting in a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 50840.0
If we subtract 0 from 71, we get 71.
Grab the next digit (0) from the dividend, add it to 71, then carry on: 710 / 142

Moving on to step 8:
142 goes into 710 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 508405.0
If we take 710 away from 710, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
142 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 508405.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
0 divided by 142 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 508405.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 508405.0 and a remainder of 0.0.
