We look at the division of 75809154 by 142 
The aim is to understand the frequency of 142 in 75809154.

Moving on to step 1:
142 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 142

Step 2:
The number 142 fits into 75 0 times, leaving a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Include the next digit (8) from the dividend after 75, then repeat: 758 / 142

On to step 3:
The number 142 fits into 758 5 times, leaving a remainder of 48.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 710 from 758, we get 48.
Take the next digit (0) from the dividend and append it to 48, then repeat: 480 / 142

Going ahead to step 4:
If we divide 480 by 142, we get 3 and a remainder of 54.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
The remainder is 54 after subtracting 426 from 480.
Take the next digit (9) from the dividend and append it to 54, then repeat: 549 / 142

Step 5:
The number 142 fits into 549 3 times, leaving a remainder of 123.
Put 3 as the next digit of the answer. 
Result so far: 533.0
Subtract 426 from 549 to get 123.
Bring next digit (1) of the dividend behind the 123 and repeat the process: 1231 / 142

Step 6:
142 can be fit into 1231 8 times, resulting in a remainder of 95.
Use 8 as the next digit of our solution. 
Result so far: 5338.0
If we take 1136 away from 1231, we end up with 95.
Bring next digit (5) of the dividend behind the 95 and repeat the process: 955 / 142

On to step 7:
When dividing 955 by 142, we get 6 with a remainder of 103.
Use 6 as the next digit of our solution. 
Result so far: 53386.0
Deduct 852 from 955 and we're left with 103.
Fetch the next digit (4) from the dividend, attach it to 103 and continue: 1034 / 142

Let's proceed to step 8:
142 can be fit into 1034 7 times, resulting in a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 533867.0
If we subtract 994 from 1034, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
The number 142 fits into 400 2 times, leaving a remainder of 116.
Write down 2 as next digit of the result. 
Result so far: 533867.2
If we take 284 away from 400, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 10:
The number 142 fits into 1160 8 times, leaving a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 533867.28
If we take 1136 away from 1160, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
142 can be fit into 240 1 times, resulting in a remainder of 98.
Write down 1 as next digit of the result. 
Result so far: 533867.281
Subtract 142 from 240 to 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.

On to step 12:
When dividing 980 by 142, we get 6 with a remainder of 128.
Record the quotient 6 as the next digit in the result. 
Result so far: 533867.2816
If we take 852 away from 980, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 13:
1280 divided by 142 is 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 533867.28169
Subtracting 1278 from 1280 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
142 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 533867.28169
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 15:
142 goes into 200 1 times with a remainder of 58.
The next digit of our result is 1. 
Result so far: 533867.2816901
Deduct 142 from 200 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 16:
142 goes into 580 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 533867.28169014
Subtract 568 from 580 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 533867.28169014 and a remainder of 1.2e-08.
