We divide 1557277 by 750
The aim is to understand the frequency of 750 in 1557277.

Going ahead to step 1:
When dividing 1 by 750, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 750

On to step 2:
750 goes into 15 0 times with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 750

Moving on to step 3:
750 can be fit into 155 0 times, resulting in a remainder of 155.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 155 leaves us with 155.
Bring next digit (7) of the dividend behind the 155 and repeat the process: 1557 / 750

Step 4:
750 can be fit into 1557 2 times, resulting in a remainder of 57.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 57 after subtracting 1500 from 1557.
Fetch the next digit (2) from the dividend, attach it to 57 and continue: 572 / 750

Step 5:
If we divide 572 by 750, we get 0 and a remainder of 572.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 572 and we're left with 572.
Bring next digit (7) of the dividend behind the 572 and repeat the process: 5727 / 750

Going ahead to step 6:
750 can be fit into 5727 7 times, resulting in a remainder of 477.
Use 7 as the next digit of our solution. 
Result so far: 207.0
The remainder is 477 after subtracting 5250 from 5727.
Bring next digit (7) of the dividend behind the 477 and repeat the process: 4777 / 750

Going ahead to step 7:
The number 750 fits into 4777 6 times, leaving a remainder of 277.
The next digit of our result is 6. 
Result so far: 2076.0
If we take 4500 away from 4777, we end up with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Step 8:
When dividing 2770 by 750, we get 3 with a remainder of 520.
The number 3 becomes the next digit in our result. 
Result so far: 2076.3
If we take 2250 away from 2770, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 9:
750 can be fit into 5200 6 times, resulting in a remainder of 700.
The number 6 becomes the next digit in our result. 
Result so far: 2076.36
Subtracting 4500 from 5200 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 10:
750 goes into 7000 9 times with a remainder of 250.
Record the quotient 9 as the next digit in the result. 
Result so far: 2076.369
Deduct 6750 from 7000 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 11:
2500 divided by 750 is 3 with a remainder of 250.
Record the quotient 3 as the next digit in the result. 
Result so far: 2076.3693
Subtract 2250 from 2500 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.

Step 12:
750 goes into 2500 3 times with a remainder of 250.
Use 3 as the next digit of our solution. 
Result so far: 2076.36933
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.

The final result is 2076.36933 with a remainder of 0.00025.
