We look at the division of 1252068 by 142 
The aim is to understand the frequency of 142 in 1252068.

Advancing to step 1:
The number 142 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 142

Moving on to step 2:
When dividing 12 by 142, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 142

Going ahead to step 3:
The number 142 fits into 125 0 times, leaving a remainder of 125.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 125 and we're left with 125.
Bring next digit (2) of the dividend behind the 125 and repeat the process: 1252 / 142

Going ahead to step 4:
142 can be fit into 1252 8 times, resulting in a remainder of 116.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 1136 from 1252 and we're left with 116.
Bring next digit (0) of the dividend behind the 116 and repeat the process: 1160 / 142

Moving on to step 5:
142 goes into 1160 8 times with a remainder of 24.
The next digit of our result is 8. 
Result so far: 88.0
The remainder is 24 after subtracting 1136 from 1160.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 142

Step 6:
If we divide 246 by 142, we get 1 and a remainder of 104.
Record the quotient 1 as the next digit in the result. 
Result so far: 881.0
If we subtract 142 from 246, we get 104.
Grab the next digit (8) from the dividend, add it to 104, then carry on: 1048 / 142

Let's proceed to step 7:
1048 divided by 142 is 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 8817.0
The remainder is 54 after subtracting 994 from 1048.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
The number 142 fits into 540 3 times, leaving a remainder of 114.
The number 3 becomes the next digit in our result. 
Result so far: 8817.3
Subtracting 426 from 540 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 9:
If we divide 1140 by 142, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 8817.38
Deduct 1136 from 1140 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
If we divide 40 by 142, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 8817.38
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
400 divided by 142 is 2 with a remainder of 116.
Put 2 as the next digit of the answer. 
Result so far: 8817.3802
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 12:
The number 142 fits into 1160 8 times, leaving a remainder of 24.
The next digit of our result is 8. 
Result so far: 8817.38028
If we subtract 1136 from 1160, we get 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 13:
When dividing 240 by 142, we get 1 with a remainder of 98.
Put 1 as the next digit of the answer. 
Result so far: 8817.380281
Deduct 142 from 240 and we're left with 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 14:
142 goes into 980 6 times with a remainder of 128.
Put 6 as the next digit of the answer. 
Result so far: 8817.3802816
Subtracting 852 from 980 leaves us 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.

On to step 15:
The number 142 fits into 1280 9 times, leaving a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 8817.38028169
If we subtract 1278 from 1280, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 8817.38028169, with a leftover of 2e-09.
