45854209 divided by 750 
The aim is to understand the frequency of 750 in 45854209.

On to step 1:
750 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 750

Advancing to step 2:
750 can be fit into 45 0 times, resulting in a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 750

Advancing to step 3:
If we divide 458 by 750, we get 0 and a remainder of 458.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 458 leaves us with 458.
Fetch the next digit (5) from the dividend, attach it to 458 and continue: 4585 / 750

Step 4:
If we divide 4585 by 750, we get 6 and a remainder of 85.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 4500 away from 4585, we end up with 85.
Append the next digit (4) from the dividend to 85 and continue with: 854 / 750

On to step 5:
750 goes into 854 1 times with a remainder of 104.
Put 1 as the next digit of the answer. 
Result so far: 61.0
If we take 750 away from 854, we end up with 104.
Bring next digit (2) of the dividend behind the 104 and repeat the process: 1042 / 750

Moving on to step 6:
If we divide 1042 by 750, we get 1 and a remainder of 292.
Put 1 as the next digit of the answer. 
Result so far: 611.0
If we subtract 750 from 1042, we get 292.
Bring next digit (0) of the dividend behind the 292 and repeat the process: 2920 / 750

Step 7:
The number 750 fits into 2920 3 times, leaving a remainder of 670.
Record the quotient 3 as the next digit in the result. 
Result so far: 6113.0
Deduct 2250 from 2920 and we're left with 670.
Append the next digit (9) from the dividend to 670 and continue with: 6709 / 750

Going ahead to step 8:
750 can be fit into 6709 8 times, resulting in a remainder of 709.
Put 8 as the next digit of the answer. 
Result so far: 61138.0
If we subtract 6000 from 6709, we get 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Let's proceed to step 9:
If we divide 7090 by 750, we get 9 and a remainder of 340.
Write down 9 as next digit of the result. 
Result so far: 61138.9
Subtract 6750 from 7090 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 10:
When dividing 3400 by 750, we get 4 with a remainder of 400.
The next digit of our result is 4. 
Result so far: 61138.94
Subtract 3000 from 3400 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.

Let's proceed to step 11:
750 can be fit into 4000 5 times, resulting in a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 61138.945
The remainder is 250 after subtracting 3750 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 12:
When dividing 2500 by 750, we get 3 with a remainder of 250.
Use 3 as the next digit of our solution. 
Result so far: 61138.9453
Deduct 2250 from 2500 and we're left 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.

Advancing to step 13:
When dividing 2500 by 750, we get 3 with a remainder of 250.
Use 3 as the next digit of our solution. 
Result so far: 61138.94533
Subtracting 2250 from 2500 leaves us 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.

Our division results in 61138.94533 with a remaining 0.00025.
