We look at the division of 43970724 by 501 
The aim is to understand the frequency of 501 in 43970724.

Moving on to step 1:
501 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 501

Going ahead to step 2:
If we divide 43 by 501, we get 0 and a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Fetch the next digit (9) from the dividend, attach it to 43 and continue: 439 / 501

Advancing to step 3:
If we divide 439 by 501, we get 0 and a remainder of 439.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 439 and we're left with 439.
Take the next digit (7) from the dividend and append it to 439, then repeat: 4397 / 501

Advancing to step 4:
501 goes into 4397 8 times with a remainder of 389.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 4008 from 4397 to get 389.
Append the next digit (0) from the dividend to 389 and continue with: 3890 / 501

Moving on to step 5:
501 goes into 3890 7 times with a remainder of 383.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Deduct 3507 from 3890 and we're left with 383.
Append the next digit (7) from the dividend to 383 and continue with: 3837 / 501

On to step 6:
501 can be fit into 3837 7 times, resulting in a remainder of 330.
Use 7 as the next digit of our solution. 
Result so far: 877.0
The remainder is 330 after subtracting 3507 from 3837.
Include the next digit (2) from the dividend after 330, then repeat: 3302 / 501

Moving on to step 7:
When dividing 3302 by 501, we get 6 with a remainder of 296.
The number 6 becomes the next digit in our result. 
Result so far: 8776.0
If we subtract 3006 from 3302, we get 296.
Bring next digit (4) of the dividend behind the 296 and repeat the process: 2964 / 501

Let's proceed to step 8:
The number 501 fits into 2964 5 times, leaving a remainder of 459.
Write down 5 as next digit of the result. 
Result so far: 87765.0
Subtract 2505 from 2964 to get 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Step 9:
When dividing 4590 by 501, we get 9 with a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 87765.9
The remainder is 81 after subtracting 4509 from 4590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 10:
When dividing 810 by 501, we get 1 with a remainder of 309.
Record the quotient 1 as the next digit in the result. 
Result so far: 87765.91
The remainder is 309 after subtracting 501 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

On to step 11:
501 goes into 3090 6 times with a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 87765.916
If we take 3006 away from 3090, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 12:
When dividing 840 by 501, we get 1 with a remainder of 339.
Use 1 as the next digit of our solution. 
Result so far: 87765.9161
The remainder is 339 after subtracting 501 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Going ahead to step 13:
When dividing 3390 by 501, we get 6 with a remainder of 384.
Use 6 as the next digit of our solution. 
Result so far: 87765.91616
Deduct 3006 from 3390 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 14:
501 can be fit into 3840 7 times, resulting in a remainder of 333.
The number 7 becomes the next digit in our result. 
Result so far: 87765.916167
Subtracting 3507 from 3840 leaves us with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Moving on to step 15:
The number 501 fits into 3330 6 times, leaving a remainder of 324.
Write down 6 as next digit of the result. 
Result so far: 87765.9161676
The remainder is 324 after subtracting 3006 from 3330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 16:
When dividing 3240 by 501, we get 6 with a remainder of 234.
The number 6 becomes the next digit in our result. 
Result so far: 87765.91616766
Subtract 3006 from 3240 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

After the division, we end up with 87765.91616766 and a remainder of 2.34e-07.
