691836 ÷ 75 
The aim is to understand the frequency of 75 in 691836.

On to step 1:
The number 75 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 75

Let's proceed to step 2:
69 divided by 75 is 0 with a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Include the next digit (1) from the dividend after 69, then repeat: 691 / 75

Let's proceed to step 3:
75 goes into 691 9 times with a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 675 from 691 to get 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 75

Step 4:
If we divide 168 by 75, we get 2 and a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 92.0
Deduct 150 from 168 and we're left with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 75

Let's proceed to step 5:
75 goes into 183 2 times with a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 922.0
Subtracting 150 from 183 leaves us with 33.
Include the next digit (6) from the dividend after 33, then repeat: 336 / 75

Advancing to step 6:
The number 75 fits into 336 4 times, leaving a remainder of 36.
The next digit of our result is 4. 
Result so far: 9224.0
If we take 300 away from 336, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 7:
360 divided by 75 is 4 with a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 9224.4
If we take 300 away from 360, we end up 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.

Moving on to step 8:
If we divide 600 by 75, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 9224.48
Subtract 600 from 600 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.

Advancing to step 9:
75 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9224.48
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.

On to step 10:
When dividing 0 by 75, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9224.48
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.

Our division results in 9224.48 with a remaining 0.0.
