764109 ÷ 75 
The aim is to understand the frequency of 75 in 764109.

Advancing to step 1:
The number 75 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 75

On to step 2:
The number 75 fits into 76 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 75 from 76 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 75

Let's proceed to step 3:
14 divided by 75 is 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 14, we get 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 75

Let's proceed to step 4:
When dividing 141 by 75, we get 1 with a remainder of 66.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
If we take 75 away from 141, we end up with 66.
Grab the next digit (0) from the dividend, add it to 66, then carry on: 660 / 75

Advancing to step 5:
The number 75 fits into 660 8 times, leaving a remainder of 60.
The next digit of our result is 8. 
Result so far: 1018.0
If we subtract 600 from 660, we get 60.
Fetch the next digit (9) from the dividend, attach it to 60 and continue: 609 / 75

Let's proceed to step 6:
When dividing 609 by 75, we get 8 with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 10188.0
The remainder is 9 after subtracting 600 from 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
If we divide 90 by 75, we get 1 and a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 10188.1
The remainder is 15 after subtracting 75 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
If we divide 150 by 75, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 10188.12
Deduct 150 from 150 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.

Advancing to step 9:
0 divided by 75 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10188.12
If we subtract 0 from 0, we 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 10:
75 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10188.12
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 10188.12, and the remainder is 0.0.
