40512587 ÷ 293 
The aim is to understand the frequency of 293 in 40512587.

Advancing to step 1:
If we divide 4 by 293, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 293

On to step 2:
The number 293 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Bring next digit (5) of the dividend behind the 40 and repeat the process: 405 / 293

On to step 3:
If we divide 405 by 293, we get 1 and a remainder of 112.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 293 from 405, we get 112.
Grab the next digit (1) from the dividend, add it to 112, then carry on: 1121 / 293

Going ahead to step 4:
If we divide 1121 by 293, we get 3 and a remainder of 242.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 242 after subtracting 879 from 1121.
Take the next digit (2) from the dividend and append it to 242, then repeat: 2422 / 293

Moving on to step 5:
When dividing 2422 by 293, we get 8 with a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 138.0
Subtract 2344 from 2422 to get 78.
Take the next digit (5) from the dividend and append it to 78, then repeat: 785 / 293

On to step 6:
785 divided by 293 is 2 with a remainder of 199.
Use 2 as the next digit of our solution. 
Result so far: 1382.0
If we take 586 away from 785, we end up with 199.
Grab the next digit (8) from the dividend, add it to 199, then carry on: 1998 / 293

Advancing to step 7:
293 goes into 1998 6 times with a remainder of 240.
Record the quotient 6 as the next digit in the result. 
Result so far: 13826.0
If we take 1758 away from 1998, we end up with 240.
Append the next digit (7) from the dividend to 240 and continue with: 2407 / 293

Moving on to step 8:
293 can be fit into 2407 8 times, resulting in a remainder of 63.
Use 8 as the next digit of our solution. 
Result so far: 138268.0
The remainder is 63 after subtracting 2344 from 2407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 9:
630 divided by 293 is 2 with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 138268.2
Deduct 586 from 630 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 10:
The number 293 fits into 440 1 times, leaving a remainder of 147.
The next digit of our result is 1. 
Result so far: 138268.21
Deduct 293 from 440 and we're left with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Advancing to step 11:
If we divide 1470 by 293, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 138268.215
Subtracting 1465 from 1470 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
The number 293 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 138268.215
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
500 divided by 293 is 1 with a remainder of 207.
Record the quotient 1 as the next digit in the result. 
Result so far: 138268.21501
Deduct 293 from 500 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Advancing to step 14:
The number 293 fits into 2070 7 times, leaving a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 138268.215017
Subtracting 2051 from 2070 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 15:
293 can be fit into 190 0 times, resulting in a remainder of 190.
Write down 0 as next digit of the result. 
Result so far: 138268.215017
Deduct 0 from 190 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 16:
The number 293 fits into 1900 6 times, leaving a remainder of 142.
Write down 6 as next digit of the result. 
Result so far: 138268.21501706
Subtract 1758 from 1900 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Our division results in 138268.21501706 with a remaining 1.42e-07.
