Let's divide 51093777 by 75
The aim is to understand the frequency of 75 in 51093777.

On to step 1:
If we divide 5 by 75, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 75

Step 2:
The number 75 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Take the next digit (0) from the dividend and append it to 51, then repeat: 510 / 75

Moving on to step 3:
If we divide 510 by 75, we get 6 and a remainder of 60.
The next digit of our result is 6. 
Result so far: 6.0
If we take 450 away from 510, we end up with 60.
Bring next digit (9) of the dividend behind the 60 and repeat the process: 609 / 75

On to step 4:
609 divided by 75 is 8 with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Subtract 600 from 609 to get 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 75

Moving on to step 5:
If we divide 93 by 75, we get 1 and a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 681.0
If we subtract 75 from 93, we get 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 75

Going ahead to step 6:
The number 75 fits into 187 2 times, leaving a remainder of 37.
The next digit of our result is 2. 
Result so far: 6812.0
If we take 150 away from 187, we end up with 37.
Take the next digit (7) from the dividend and append it to 37, then repeat: 377 / 75

On to step 7:
75 goes into 377 5 times with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 68125.0
Subtracting 375 from 377 leaves us with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 75

Advancing to step 8:
75 can be fit into 27 0 times, resulting in a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 681250.0
Subtract 0 from 27 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
75 goes into 270 3 times with a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 681250.3
Subtracting 225 from 270 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
If we divide 450 by 75, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 681250.36
Subtract 450 from 450 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.

Let's proceed to step 11:
When dividing 0 by 75, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 681250.36
Subtracting 0 from 0 leaves us 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.

Moving on to step 12:
75 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 681250.36
If we take 0 away from 0, we end up 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.

The quotient of the division is 681250.36, and the remainder is 0.0.
