72430256 divided by 501 
The aim is to understand the frequency of 501 in 72430256.

On to step 1:
7 divided by 501 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 501

Moving on to step 2:
501 can be fit into 72 0 times, resulting in a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Take the next digit (4) from the dividend and append it to 72, then repeat: 724 / 501

Moving on to step 3:
724 divided by 501 is 1 with a remainder of 223.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 223 after subtracting 501 from 724.
Grab the next digit (3) from the dividend, add it to 223, then carry on: 2233 / 501

Moving on to step 4:
2233 divided by 501 is 4 with a remainder of 229.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 2004 from 2233, we get 229.
Include the next digit (0) from the dividend after 229, then repeat: 2290 / 501

Going ahead to step 5:
2290 divided by 501 is 4 with a remainder of 286.
Write down 4 as next digit of the result. 
Result so far: 144.0
The remainder is 286 after subtracting 2004 from 2290.
Fetch the next digit (2) from the dividend, attach it to 286 and continue: 2862 / 501

Going ahead to step 6:
501 goes into 2862 5 times with a remainder of 357.
Write down 5 as next digit of the result. 
Result so far: 1445.0
If we subtract 2505 from 2862, we get 357.
Include the next digit (5) from the dividend after 357, then repeat: 3575 / 501

Advancing to step 7:
If we divide 3575 by 501, we get 7 and a remainder of 68.
The number 7 becomes the next digit in our result. 
Result so far: 14457.0
Subtracting 3507 from 3575 leaves us with 68.
Fetch the next digit (6) from the dividend, attach it to 68 and continue: 686 / 501

Let's proceed to step 8:
The number 501 fits into 686 1 times, leaving a remainder of 185.
Put 1 as the next digit of the answer. 
Result so far: 144571.0
Subtract 501 from 686 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 9:
501 can be fit into 1850 3 times, resulting in a remainder of 347.
The next digit of our result is 3. 
Result so far: 144571.3
Deduct 1503 from 1850 and we're left with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Let's proceed to step 10:
If we divide 3470 by 501, we get 6 and a remainder of 464.
Use 6 as the next digit of our solution. 
Result so far: 144571.36
If we subtract 3006 from 3470, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Going ahead to step 11:
If we divide 4640 by 501, we get 9 and a remainder of 131.
Use 9 as the next digit of our solution. 
Result so far: 144571.369
Deduct 4509 from 4640 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 12:
The number 501 fits into 1310 2 times, leaving a remainder of 308.
Record the quotient 2 as the next digit in the result. 
Result so far: 144571.3692
If we subtract 1002 from 1310, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 13:
When dividing 3080 by 501, we get 6 with a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 144571.36926
The remainder is 74 after subtracting 3006 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 14:
If we divide 740 by 501, we get 1 and a remainder of 239.
The number 1 becomes the next digit in our result. 
Result so far: 144571.369261
Deduct 501 from 740 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Advancing to step 15:
The number 501 fits into 2390 4 times, leaving a remainder of 386.
Record the quotient 4 as the next digit in the result. 
Result so far: 144571.3692614
If we take 2004 away from 2390, we end up with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Going ahead to step 16:
The number 501 fits into 3860 7 times, leaving a remainder of 353.
Use 7 as the next digit of our solution. 
Result so far: 144571.36926147
The remainder is 353 after subtracting 3507 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

The final result is 144571.36926147 with a remainder of 3.53e-07.
