We look at the division of 40101936 by 925 
The aim is to understand the frequency of 925 in 40101936.

Let's proceed to step 1:
The number 925 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 925

Moving on to step 2:
When dividing 40 by 925, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 925

Going ahead to step 3:
925 can be fit into 401 0 times, resulting in a remainder of 401.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 401, we end up with 401.
Grab the next digit (0) from the dividend, add it to 401, then carry on: 4010 / 925

Advancing to step 4:
4010 divided by 925 is 4 with a remainder of 310.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 3700 away from 4010, we end up with 310.
Fetch the next digit (1) from the dividend, attach it to 310 and continue: 3101 / 925

Moving on to step 5:
3101 divided by 925 is 3 with a remainder of 326.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we take 2775 away from 3101, we end up with 326.
Bring next digit (9) of the dividend behind the 326 and repeat the process: 3269 / 925

Advancing to step 6:
The number 925 fits into 3269 3 times, leaving a remainder of 494.
Record the quotient 3 as the next digit in the result. 
Result so far: 433.0
Deduct 2775 from 3269 and we're left with 494.
Bring next digit (3) of the dividend behind the 494 and repeat the process: 4943 / 925

Let's proceed to step 7:
When dividing 4943 by 925, we get 5 with a remainder of 318.
Put 5 as the next digit of the answer. 
Result so far: 4335.0
If we take 4625 away from 4943, we end up with 318.
Include the next digit (6) from the dividend after 318, then repeat: 3186 / 925

Step 8:
The number 925 fits into 3186 3 times, leaving a remainder of 411.
Put 3 as the next digit of the answer. 
Result so far: 43353.0
The remainder is 411 after subtracting 2775 from 3186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Going ahead to step 9:
925 goes into 4110 4 times with a remainder of 410.
Record the quotient 4 as the next digit in the result. 
Result so far: 43353.4
If we subtract 3700 from 4110, we get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 10:
925 can be fit into 4100 4 times, resulting in a remainder of 400.
The next digit of our result is 4. 
Result so far: 43353.44
Subtract 3700 from 4100 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 43353.44 with a remainder of 0.4.
