We divide 66431591 by 750
The aim is to understand the frequency of 750 in 66431591.

Advancing to step 1:
750 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 750

On to step 2:
66 divided by 750 is 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 750

Going ahead to step 3:
When dividing 664 by 750, we get 0 with a remainder of 664.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 664 to get 664.
Append the next digit (3) from the dividend to 664 and continue with: 6643 / 750

Moving on to step 4:
750 can be fit into 6643 8 times, resulting in a remainder of 643.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 6000 from 6643 and we're left with 643.
Grab the next digit (1) from the dividend, add it to 643, then carry on: 6431 / 750

Going ahead to step 5:
750 can be fit into 6431 8 times, resulting in a remainder of 431.
Write down 8 as next digit of the result. 
Result so far: 88.0
Deduct 6000 from 6431 and we're left with 431.
Take the next digit (5) from the dividend and append it to 431, then repeat: 4315 / 750

Going ahead to step 6:
4315 divided by 750 is 5 with a remainder of 565.
The next digit of our result is 5. 
Result so far: 885.0
The remainder is 565 after subtracting 3750 from 4315.
Fetch the next digit (9) from the dividend, attach it to 565 and continue: 5659 / 750

Let's proceed to step 7:
5659 divided by 750 is 7 with a remainder of 409.
Use 7 as the next digit of our solution. 
Result so far: 8857.0
Deduct 5250 from 5659 and we're left with 409.
Append the next digit (1) from the dividend to 409 and continue with: 4091 / 750

Step 8:
When dividing 4091 by 750, we get 5 with a remainder of 341.
Record the quotient 5 as the next digit in the result. 
Result so far: 88575.0
The remainder is 341 after subtracting 3750 from 4091.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Step 9:
If we divide 3410 by 750, we get 4 and a remainder of 410.
The next digit of our result is 4. 
Result so far: 88575.4
If we take 3000 away from 3410, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 10:
4100 divided by 750 is 5 with a remainder of 350.
The number 5 becomes the next digit in our result. 
Result so far: 88575.45
Subtracting 3750 from 4100 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 11:
The number 750 fits into 3500 4 times, leaving a remainder of 500.
The next digit of our result is 4. 
Result so far: 88575.454
If we subtract 3000 from 3500, 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.

Step 12:
5000 divided by 750 is 6 with a remainder of 500.
Use 6 as the next digit of our solution. 
Result so far: 88575.4546
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:
The number 750 fits into 5000 6 times, leaving a remainder of 500.
Write down 6 as next digit of the result. 
Result so far: 88575.45466
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.

The quotient of the division is 88575.45466, and the remainder is 0.0005.
