We look at the division of 72049260 by 143 
The aim is to understand the frequency of 143 in 72049260.

Moving on to step 1:
143 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 143

Going ahead to step 2:
143 can be fit into 72 0 times, resulting in a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Grab the next digit (0) from the dividend, add it to 72, then carry on: 720 / 143

Going ahead to step 3:
When dividing 720 by 143, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 715 away from 720, we end up with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 143

Going ahead to step 4:
The number 143 fits into 54 0 times, leaving a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
If we subtract 0 from 54, we get 54.
Fetch the next digit (9) from the dividend, attach it to 54 and continue: 549 / 143

Let's proceed to step 5:
143 goes into 549 3 times with a remainder of 120.
Put 3 as the next digit of the answer. 
Result so far: 503.0
If we take 429 away from 549, we end up with 120.
Append the next digit (2) from the dividend to 120 and continue with: 1202 / 143

On to step 6:
143 goes into 1202 8 times with a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 5038.0
Subtracting 1144 from 1202 leaves us with 58.
Include the next digit (6) from the dividend after 58, then repeat: 586 / 143

On to step 7:
143 goes into 586 4 times with a remainder of 14.
The next digit of our result is 4. 
Result so far: 50384.0
Subtract 572 from 586 to get 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 143

Moving on to step 8:
If we divide 140 by 143, we get 0 and a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 503840.0
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.

Let's proceed to step 9:
143 goes into 1400 9 times with a remainder of 113.
Write down 9 as next digit of the result. 
Result so far: 503840.9
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.

Let's proceed to step 10:
If we divide 1130 by 143, we get 7 and a remainder of 129.
Put 7 as the next digit of the answer. 
Result so far: 503840.97
Deduct 1001 from 1130 and we're left 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 11:
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: 503840.979
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 12:
30 divided by 143 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 503840.979
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.

On to step 13:
The number 143 fits into 300 2 times, leaving a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 503840.97902
If we subtract 286 from 300, we get 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 14:
If we divide 140 by 143, we get 0 and a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 503840.97902
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.

On to step 15:
If we divide 1400 by 143, we get 9 and a remainder of 113.
Use 9 as the next digit of our solution. 
Result so far: 503840.9790209
Subtract 1287 from 1400 to 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.

Advancing to step 16:
143 goes into 1130 7 times with a remainder of 129.
Use 7 as the next digit of our solution. 
Result so far: 503840.97902097
Deduct 1001 from 1130 and we're left 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.

The quotient of the division is 503840.97902097, and the remainder is 1.29e-07.
