We look at the division of 81313039 by 142 
We're looking to find how many times 142 goes into 81313039.

Moving on to step 1:
142 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 142

Let's proceed to step 2:
The number 142 fits into 81 0 times, leaving a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Fetch the next digit (3) from the dividend, attach it to 81 and continue: 813 / 142

Advancing to step 3:
142 goes into 813 5 times with a remainder of 103.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 710 from 813 leaves us with 103.
Include the next digit (1) from the dividend after 103, then repeat: 1031 / 142

Moving on to step 4:
If we divide 1031 by 142, we get 7 and a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Subtract 994 from 1031 to get 37.
Append the next digit (3) from the dividend to 37 and continue with: 373 / 142

On to step 5:
The number 142 fits into 373 2 times, leaving a remainder of 89.
Put 2 as the next digit of the answer. 
Result so far: 572.0
If we take 284 away from 373, we end up with 89.
Grab the next digit (0) from the dividend, add it to 89, then carry on: 890 / 142

Moving on to step 6:
The number 142 fits into 890 6 times, leaving a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 5726.0
Subtract 852 from 890 to get 38.
Fetch the next digit (3) from the dividend, attach it to 38 and continue: 383 / 142

Moving on to step 7:
When dividing 383 by 142, we get 2 with a remainder of 99.
The number 2 becomes the next digit in our result. 
Result so far: 57262.0
If we take 284 away from 383, we end up with 99.
Fetch the next digit (9) from the dividend, attach it to 99 and continue: 999 / 142

Let's proceed to step 8:
When dividing 999 by 142, we get 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 572627.0
Subtract 994 from 999 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
When dividing 50 by 142, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 572627.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
142 can be fit into 500 3 times, resulting in a remainder of 74.
Put 3 as the next digit of the answer. 
Result so far: 572627.03
If we take 426 away from 500, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 11:
The number 142 fits into 740 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 572627.035
Subtracting 710 from 740 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
300 divided by 142 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 572627.0352
Deduct 284 from 300 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
160 divided by 142 is 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 572627.03521
The remainder is 18 after subtracting 142 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 14:
When dividing 180 by 142, we get 1 with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 572627.035211
The remainder is 38 after subtracting 142 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 572627.035211, and the remainder is 3.8e-06.
