75246351 divided by 75 
The aim is to understand the frequency of 75 in 75246351.

Moving on to step 1:
When dividing 7 by 75, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 75

Going ahead to step 2:
75 goes into 75 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 75 from 75 and we're left with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 75

Let's proceed to step 3:
If we divide 2 by 75, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 2, we get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 75

On to step 4:
24 divided by 75 is 0 with a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Subtracting 0 from 24 leaves us with 24.
Append the next digit (6) from the dividend to 24 and continue with: 246 / 75

Step 5:
246 divided by 75 is 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 1003.0
Deduct 225 from 246 and we're left with 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 75

On to step 6:
When dividing 213 by 75, we get 2 with a remainder of 63.
Put 2 as the next digit of the answer. 
Result so far: 10032.0
Deduct 150 from 213 and we're left with 63.
Take the next digit (5) from the dividend and append it to 63, then repeat: 635 / 75

Going ahead to step 7:
If we divide 635 by 75, we get 8 and a remainder of 35.
The next digit of our result is 8. 
Result so far: 100328.0
The remainder is 35 after subtracting 600 from 635.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 75

On to step 8:
If we divide 351 by 75, we get 4 and a remainder of 51.
Use 4 as the next digit of our solution. 
Result so far: 1003284.0
Deduct 300 from 351 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 9:
If we divide 510 by 75, we get 6 and a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 1003284.6
Deduct 450 from 510 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
The number 75 fits into 600 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 1003284.68
Deduct 600 from 600 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.

Going ahead to step 11:
If we divide 0 by 75, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1003284.68
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.

Going ahead to step 12:
75 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1003284.68
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 quotient of the division is 1003284.68, and the remainder is 0.0.
