78433349 ÷ 750 
The aim is to understand the frequency of 750 in 78433349.

On to step 1:
When dividing 7 by 750, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 750

Let's proceed to step 2:
If we divide 78 by 750, we get 0 and a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Append the next digit (4) from the dividend to 78 and continue with: 784 / 750

Moving on to step 3:
If we divide 784 by 750, we get 1 and a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 750 from 784, we get 34.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 750

Step 4:
When dividing 343 by 750, we get 0 with a remainder of 343.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 343 to get 343.
Append the next digit (3) from the dividend to 343 and continue with: 3433 / 750

Let's proceed to step 5:
The number 750 fits into 3433 4 times, leaving a remainder of 433.
Use 4 as the next digit of our solution. 
Result so far: 104.0
If we take 3000 away from 3433, we end up with 433.
Take the next digit (3) from the dividend and append it to 433, then repeat: 4333 / 750

Moving on to step 6:
750 goes into 4333 5 times with a remainder of 583.
Write down 5 as next digit of the result. 
Result so far: 1045.0
Subtracting 3750 from 4333 leaves us with 583.
Take the next digit (4) from the dividend and append it to 583, then repeat: 5834 / 750

Moving on to step 7:
5834 divided by 750 is 7 with a remainder of 584.
Use 7 as the next digit of our solution. 
Result so far: 10457.0
Subtract 5250 from 5834 to get 584.
Grab the next digit (9) from the dividend, add it to 584, then carry on: 5849 / 750

Going ahead to step 8:
If we divide 5849 by 750, we get 7 and a remainder of 599.
Use 7 as the next digit of our solution. 
Result so far: 104577.0
Subtract 5250 from 5849 to get 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Let's proceed to step 9:
If we divide 5990 by 750, we get 7 and a remainder of 740.
The next digit of our result is 7. 
Result so far: 104577.7
Deduct 5250 from 5990 and we're left with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

On to step 10:
750 can be fit into 7400 9 times, resulting in a remainder of 650.
Use 9 as the next digit of our solution. 
Result so far: 104577.79
Deduct 6750 from 7400 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Advancing to step 11:
750 can be fit into 6500 8 times, resulting in a remainder of 500.
The next digit of our result is 8. 
Result so far: 104577.798
The remainder is 500 after subtracting 6000 from 6500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 12:
The number 750 fits into 5000 6 times, leaving a remainder of 500.
The next digit of our result is 6. 
Result so far: 104577.7986
If we subtract 4500 from 5000, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 13:
750 can be fit into 5000 6 times, resulting in a remainder of 500.
The number 6 becomes the next digit in our result. 
Result so far: 104577.79866
Subtracting 4500 from 5000 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Our division results in 104577.79866 with a remaining 0.0005.
