We're dividing 86170114 by 143 
The aim is to understand the frequency of 143 in 86170114.

Going ahead to step 1:
143 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 143

Advancing to step 2:
The number 143 fits into 86 0 times, leaving a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Bring next digit (1) of the dividend behind the 86 and repeat the process: 861 / 143

On to step 3:
If we divide 861 by 143, we get 6 and a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 858 away from 861, we end up with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 143

Advancing to step 4:
When dividing 37 by 143, we get 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 60.0
If we subtract 0 from 37, we get 37.
Fetch the next digit (0) from the dividend, attach it to 37 and continue: 370 / 143

Advancing to step 5:
143 can be fit into 370 2 times, resulting in a remainder of 84.
Put 2 as the next digit of the answer. 
Result so far: 602.0
The remainder is 84 after subtracting 286 from 370.
Fetch the next digit (1) from the dividend, attach it to 84 and continue: 841 / 143

Moving on to step 6:
If we divide 841 by 143, we get 5 and a remainder of 126.
Record the quotient 5 as the next digit in the result. 
Result so far: 6025.0
Subtracting 715 from 841 leaves us with 126.
Take the next digit (1) from the dividend and append it to 126, then repeat: 1261 / 143

Step 7:
When dividing 1261 by 143, we get 8 with a remainder of 117.
Put 8 as the next digit of the answer. 
Result so far: 60258.0
If we take 1144 away from 1261, we end up with 117.
Fetch the next digit (4) from the dividend, attach it to 117 and continue: 1174 / 143

Let's proceed to step 8:
1174 divided by 143 is 8 with a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 602588.0
The remainder is 30 after subtracting 1144 from 1174.
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 9:
143 can be fit into 300 2 times, resulting in a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 602588.2
Deduct 286 from 300 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
When dividing 140 by 143, we get 0 with a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 602588.2
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 11:
When dividing 1400 by 143, we get 9 with a remainder of 113.
Use 9 as the next digit of our solution. 
Result so far: 602588.209
Deduct 1287 from 1400 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Step 12:
1130 divided by 143 is 7 with a remainder of 129.
Write down 7 as next digit of the result. 
Result so far: 602588.2097
Subtracting 1001 from 1130 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Let's proceed to step 13:
If we divide 1290 by 143, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 602588.20979
If we subtract 1287 from 1290, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
143 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 602588.20979
Subtracting 0 from 30 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.

Advancing to step 15:
When dividing 300 by 143, we get 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 602588.2097902
Subtracting 286 from 300 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 16:
The number 143 fits into 140 0 times, leaving a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 602588.2097902
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final result is 602588.2097902 with a remainder of 1.4e-07.
