We look at the division of 94087181 by 143 
The aim is to understand the frequency of 143 in 94087181.

Going ahead to step 1:
143 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 143

Moving on to step 2:
94 divided by 143 is 0 with a remainder of 94.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 94 after subtracting 0 from 94.
Fetch the next digit (0) from the dividend, attach it to 94 and continue: 940 / 143

Going ahead to step 3:
If we divide 940 by 143, we get 6 and a remainder of 82.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 82 after subtracting 858 from 940.
Fetch the next digit (8) from the dividend, attach it to 82 and continue: 828 / 143

On to step 4:
143 goes into 828 5 times with a remainder of 113.
Put 5 as the next digit of the answer. 
Result so far: 65.0
Subtracting 715 from 828 leaves us with 113.
Fetch the next digit (7) from the dividend, attach it to 113 and continue: 1137 / 143

On to step 5:
When dividing 1137 by 143, we get 7 with a remainder of 136.
Record the quotient 7 as the next digit in the result. 
Result so far: 657.0
If we take 1001 away from 1137, we end up with 136.
Take the next digit (1) from the dividend and append it to 136, then repeat: 1361 / 143

Moving on to step 6:
The number 143 fits into 1361 9 times, leaving a remainder of 74.
The number 9 becomes the next digit in our result. 
Result so far: 6579.0
If we subtract 1287 from 1361, we get 74.
Append the next digit (8) from the dividend to 74 and continue with: 748 / 143

Let's proceed to step 7:
The number 143 fits into 748 5 times, leaving a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 65795.0
The remainder is 33 after subtracting 715 from 748.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 143

Step 8:
331 divided by 143 is 2 with a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 657952.0
Subtract 286 from 331 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
143 goes into 450 3 times with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 657952.3
If we subtract 429 from 450, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 10:
The number 143 fits into 210 1 times, leaving a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 657952.31
If we take 143 away from 210, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 11:
143 can be fit into 670 4 times, resulting in a remainder of 98.
Use 4 as the next digit of our solution. 
Result so far: 657952.314
If we take 572 away from 670, we end up 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.

Advancing to step 12:
The number 143 fits into 980 6 times, leaving a remainder of 122.
Use 6 as the next digit of our solution. 
Result so far: 657952.3146
Deduct 858 from 980 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 13:
143 goes into 1220 8 times with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 657952.31468
The remainder is 76 after subtracting 1144 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 14:
760 divided by 143 is 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 657952.314685
If we take 715 away from 760, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 15:
143 goes into 450 3 times with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 657952.3146853
Deduct 429 from 450 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 16:
When dividing 210 by 143, we get 1 with a remainder of 67.
The number 1 becomes the next digit in our result. 
Result so far: 657952.31468531
The remainder is 67 after subtracting 143 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

After the division, we end up with 657952.31468531 and a remainder of 6.7e-08.
