87449949 divided by 750 
The aim is to understand the frequency of 750 in 87449949.

Step 1:
When dividing 8 by 750, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 750

Moving on to step 2:
87 divided by 750 is 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Take the next digit (4) from the dividend and append it to 87, then repeat: 874 / 750

Step 3:
If we divide 874 by 750, we get 1 and a remainder of 124.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 750 from 874 and we're left with 124.
Bring next digit (4) of the dividend behind the 124 and repeat the process: 1244 / 750

Step 4:
If we divide 1244 by 750, we get 1 and a remainder of 494.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 494 after subtracting 750 from 1244.
Take the next digit (9) from the dividend and append it to 494, then repeat: 4949 / 750

Step 5:
750 can be fit into 4949 6 times, resulting in a remainder of 449.
The next digit of our result is 6. 
Result so far: 116.0
If we subtract 4500 from 4949, we get 449.
Bring next digit (9) of the dividend behind the 449 and repeat the process: 4499 / 750

On to step 6:
If we divide 4499 by 750, we get 5 and a remainder of 749.
Use 5 as the next digit of our solution. 
Result so far: 1165.0
If we take 3750 away from 4499, we end up with 749.
Append the next digit (4) from the dividend to 749 and continue with: 7494 / 750

Step 7:
If we divide 7494 by 750, we get 9 and a remainder of 744.
Write down 9 as next digit of the result. 
Result so far: 11659.0
If we subtract 6750 from 7494, we get 744.
Fetch the next digit (9) from the dividend, attach it to 744 and continue: 7449 / 750

Let's proceed to step 8:
The number 750 fits into 7449 9 times, leaving a remainder of 699.
The next digit of our result is 9. 
Result so far: 116599.0
Subtract 6750 from 7449 to get 699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Moving on to step 9:
If we divide 6990 by 750, we get 9 and a remainder of 240.
Put 9 as the next digit of the answer. 
Result so far: 116599.9
Subtract 6750 from 6990 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 10:
2400 divided by 750 is 3 with a remainder of 150.
Record the quotient 3 as the next digit in the result. 
Result so far: 116599.93
If we take 2250 away from 2400, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 11:
1500 divided by 750 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 116599.932
Deduct 1500 from 1500 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
750 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 116599.932
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 13:
750 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 116599.932
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 116599.932 with a remainder of 0.0.
