Let's divide 40889731 by 750
The aim is to understand the frequency of 750 in 40889731.

Advancing to step 1:
750 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
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 / 750

Step 2:
750 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 750

Step 3:
When dividing 408 by 750, we get 0 with a remainder of 408.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 408 and we're left with 408.
Take the next digit (8) from the dividend and append it to 408, then repeat: 4088 / 750

Moving on to step 4:
The number 750 fits into 4088 5 times, leaving a remainder of 338.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 3750 from 4088 and we're left with 338.
Grab the next digit (9) from the dividend, add it to 338, then carry on: 3389 / 750

Moving on to step 5:
750 can be fit into 3389 4 times, resulting in a remainder of 389.
Use 4 as the next digit of our solution. 
Result so far: 54.0
The remainder is 389 after subtracting 3000 from 3389.
Fetch the next digit (7) from the dividend, attach it to 389 and continue: 3897 / 750

Advancing to step 6:
3897 divided by 750 is 5 with a remainder of 147.
Use 5 as the next digit of our solution. 
Result so far: 545.0
Subtracting 3750 from 3897 leaves us with 147.
Take the next digit (3) from the dividend and append it to 147, then repeat: 1473 / 750

On to step 7:
750 goes into 1473 1 times with a remainder of 723.
The next digit of our result is 1. 
Result so far: 5451.0
If we take 750 away from 1473, we end up with 723.
Append the next digit (1) from the dividend to 723 and continue with: 7231 / 750

Going ahead to step 8:
750 can be fit into 7231 9 times, resulting in a remainder of 481.
The next digit of our result is 9. 
Result so far: 54519.0
The remainder is 481 after subtracting 6750 from 7231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

On to step 9:
750 can be fit into 4810 6 times, resulting in a remainder of 310.
The number 6 becomes the next digit in our result. 
Result so far: 54519.6
Subtract 4500 from 4810 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 10:
When dividing 3100 by 750, we get 4 with a remainder of 100.
Put 4 as the next digit of the answer. 
Result so far: 54519.64
Subtract 3000 from 3100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
If we divide 1000 by 750, we get 1 and a remainder of 250.
Put 1 as the next digit of the answer. 
Result so far: 54519.641
Subtract 750 from 1000 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 12:
2500 divided by 750 is 3 with a remainder of 250.
Put 3 as the next digit of the answer. 
Result so far: 54519.6413
The remainder is 250 after subtracting 2250 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 13:
If we divide 2500 by 750, we get 3 and a remainder of 250.
Put 3 as the next digit of the answer. 
Result so far: 54519.64133
If we take 2250 away from 2500, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The final result is 54519.64133 with a remainder of 0.00025.
