Let's divide 8537669 by 143
The aim is to understand the frequency of 143 in 8537669.

Moving on to step 1:
143 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 143

Advancing to step 2:
143 can be fit into 85 0 times, resulting in a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Grab the next digit (3) from the dividend, add it to 85, then carry on: 853 / 143

Let's proceed to step 3:
If we divide 853 by 143, we get 5 and a remainder of 138.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 138 after subtracting 715 from 853.
Fetch the next digit (7) from the dividend, attach it to 138 and continue: 1387 / 143

Moving on to step 4:
143 goes into 1387 9 times with a remainder of 100.
Write down 9 as next digit of the result. 
Result so far: 59.0
The remainder is 100 after subtracting 1287 from 1387.
Include the next digit (6) from the dividend after 100, then repeat: 1006 / 143

Advancing to step 5:
The number 143 fits into 1006 7 times, leaving a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 597.0
Subtracting 1001 from 1006 leaves us with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 143

Step 6:
If we divide 56 by 143, we get 0 and a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 5970.0
If we take 0 away from 56, we end up with 56.
Include the next digit (9) from the dividend after 56, then repeat: 569 / 143

Advancing to step 7:
When dividing 569 by 143, we get 3 with a remainder of 140.
Record the quotient 3 as the next digit in the result. 
Result so far: 59703.0
Subtracting 429 from 569 leaves us 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.

Moving on to step 8:
143 goes into 1400 9 times with a remainder of 113.
Write down 9 as next digit of the result. 
Result so far: 59703.9
If we take 1287 away from 1400, we end up 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.

Advancing to step 9:
143 can be fit into 1130 7 times, resulting in a remainder of 129.
The number 7 becomes the next digit in our result. 
Result so far: 59703.97
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.

Going ahead to step 10:
143 goes into 1290 9 times with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 59703.979
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.

Going ahead to step 11:
When dividing 30 by 143, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 59703.979
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.

Let's proceed to step 12:
When dividing 300 by 143, we get 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 59703.97902
The remainder is 14 after subtracting 286 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
143 goes into 140 0 times with a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 59703.97902
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 14:
143 can be fit into 1400 9 times, resulting in a remainder of 113.
The next digit of our result is 9. 
Result so far: 59703.9790209
If we subtract 1287 from 1400, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 15:
When dividing 1130 by 143, we get 7 with a remainder of 129.
The next digit of our result is 7. 
Result so far: 59703.97902097
If we subtract 1001 from 1130, we get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

The final result is 59703.97902097 with a remainder of 1.29e-07.
