Let's divide 58666781 by 143
The aim is to understand the frequency of 143 in 58666781.

Step 1:
The number 143 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 143

Advancing to step 2:
If we divide 58 by 143, we get 0 and a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Bring next digit (6) of the dividend behind the 58 and repeat the process: 586 / 143

Step 3:
If we divide 586 by 143, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 572 from 586 leaves us with 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 143

On to step 4:
The number 143 fits into 146 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Deduct 143 from 146 and we're left with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 143

On to step 5:
36 divided by 143 is 0 with a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 410.0
If we take 0 away from 36, we end up with 36.
Append the next digit (7) from the dividend to 36 and continue with: 367 / 143

Moving on to step 6:
143 can be fit into 367 2 times, resulting in a remainder of 81.
The number 2 becomes the next digit in our result. 
Result so far: 4102.0
The remainder is 81 after subtracting 286 from 367.
Take the next digit (8) from the dividend and append it to 81, then repeat: 818 / 143

Advancing to step 7:
The number 143 fits into 818 5 times, leaving a remainder of 103.
Use 5 as the next digit of our solution. 
Result so far: 41025.0
If we take 715 away from 818, we end up with 103.
Bring next digit (1) of the dividend behind the 103 and repeat the process: 1031 / 143

Going ahead to step 8:
If we divide 1031 by 143, we get 7 and a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 410257.0
Deduct 1001 from 1031 and we're left 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.

Going ahead to step 9:
300 divided by 143 is 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 410257.2
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.

Let's proceed to step 10:
143 goes into 140 0 times with a remainder of 140.
The next digit of our result is 0. 
Result so far: 410257.2
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.

Step 11:
143 goes into 1400 9 times with a remainder of 113.
Put 9 as the next digit of the answer. 
Result so far: 410257.209
The remainder is 113 after subtracting 1287 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Let's proceed to step 12:
If we divide 1130 by 143, we get 7 and a remainder of 129.
Use 7 as the next digit of our solution. 
Result so far: 410257.2097
The remainder is 129 after subtracting 1001 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 13:
143 can be fit into 1290 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 410257.20979
Deduct 1287 from 1290 and we're left with 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 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 410257.20979
If we subtract 0 from 30, we get 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:
If we divide 300 by 143, we get 2 and a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 410257.2097902
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.

Step 16:
143 goes into 140 0 times with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 410257.2097902
Subtract 0 from 140 to 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.

In conclusion, the division gives 410257.2097902 with a balance of 1.4e-07.
