We divide 12017318 by 143
The aim is to understand the frequency of 143 in 12017318.

Advancing to step 1:
143 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 143

Moving on to step 2:
If we divide 12 by 143, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 143

Step 3:
120 divided by 143 is 0 with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 120, we end up with 120.
Append the next digit (1) from the dividend to 120 and continue with: 1201 / 143

Moving on to step 4:
143 goes into 1201 8 times with a remainder of 57.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 1144 from 1201, we get 57.
Append the next digit (7) from the dividend to 57 and continue with: 577 / 143

Moving on to step 5:
When dividing 577 by 143, we get 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 84.0
Subtracting 572 from 577 leaves us with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 143

Let's proceed to step 6:
The number 143 fits into 53 0 times, leaving a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 840.0
If we subtract 0 from 53, we get 53.
Take the next digit (1) from the dividend and append it to 53, then repeat: 531 / 143

Moving on to step 7:
The number 143 fits into 531 3 times, leaving a remainder of 102.
The next digit of our result is 3. 
Result so far: 8403.0
Deduct 429 from 531 and we're left with 102.
Append the next digit (8) from the dividend to 102 and continue with: 1028 / 143

Going ahead to step 8:
If we divide 1028 by 143, we get 7 and a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 84037.0
If we subtract 1001 from 1028, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
If we divide 270 by 143, we get 1 and a remainder of 127.
Put 1 as the next digit of the answer. 
Result so far: 84037.1
Subtracting 143 from 270 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Let's proceed to step 10:
If we divide 1270 by 143, we get 8 and a remainder of 126.
The number 8 becomes the next digit in our result. 
Result so far: 84037.18
If we take 1144 away from 1270, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 11:
The number 143 fits into 1260 8 times, leaving a remainder of 116.
Write down 8 as next digit of the result. 
Result so far: 84037.188
Deduct 1144 from 1260 and we're left 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.

The final outcome is 84037.188, with a leftover of 0.0116.
