We look at the division of 71366739 by 142 
The aim is to understand the frequency of 142 in 71366739.

Going ahead to step 1:
142 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 142

Advancing to step 2:
142 goes into 71 0 times with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Bring next digit (3) of the dividend behind the 71 and repeat the process: 713 / 142

Step 3:
When dividing 713 by 142, we get 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 710 away from 713, we end up with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 142

Step 4:
142 goes into 36 0 times with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
If we take 0 away from 36, we end up with 36.
Append the next digit (6) from the dividend to 36 and continue with: 366 / 142

Advancing to step 5:
366 divided by 142 is 2 with a remainder of 82.
Use 2 as the next digit of our solution. 
Result so far: 502.0
If we subtract 284 from 366, we get 82.
Include the next digit (7) from the dividend after 82, then repeat: 827 / 142

Step 6:
142 can be fit into 827 5 times, resulting in a remainder of 117.
Use 5 as the next digit of our solution. 
Result so far: 5025.0
Subtract 710 from 827 to get 117.
Append the next digit (3) from the dividend to 117 and continue with: 1173 / 142

Let's proceed to step 7:
When dividing 1173 by 142, we get 8 with a remainder of 37.
Record the quotient 8 as the next digit in the result. 
Result so far: 50258.0
Deduct 1136 from 1173 and we're left with 37.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 142

On to step 8:
379 divided by 142 is 2 with a remainder of 95.
Write down 2 as next digit of the result. 
Result so far: 502582.0
If we take 284 away from 379, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 9:
950 divided by 142 is 6 with a remainder of 98.
Put 6 as the next digit of the answer. 
Result so far: 502582.6
If we subtract 852 from 950, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 10:
980 divided by 142 is 6 with a remainder of 128.
Write down 6 as next digit of the result. 
Result so far: 502582.66
The remainder is 128 after subtracting 852 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final outcome is 502582.66, with a leftover of 0.128.
