We divide 649389 by 75
The aim is to understand the frequency of 75 in 649389.

Advancing to step 1:
6 divided by 75 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 75

Going ahead to step 2:
When dividing 64 by 75, we get 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Append the next digit (9) from the dividend to 64 and continue with: 649 / 75

Step 3:
75 goes into 649 8 times with a remainder of 49.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 600 from 649 leaves us with 49.
Take the next digit (3) from the dividend and append it to 49, then repeat: 493 / 75

Moving on to step 4:
75 can be fit into 493 6 times, resulting in a remainder of 43.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtracting 450 from 493 leaves us with 43.
Bring next digit (8) of the dividend behind the 43 and repeat the process: 438 / 75

Step 5:
The number 75 fits into 438 5 times, leaving a remainder of 63.
Write down 5 as next digit of the result. 
Result so far: 865.0
Subtracting 375 from 438 leaves us with 63.
Append the next digit (9) from the dividend to 63 and continue with: 639 / 75

On to step 6:
639 divided by 75 is 8 with a remainder of 39.
Use 8 as the next digit of our solution. 
Result so far: 8658.0
The remainder is 39 after subtracting 600 from 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 7:
If we divide 390 by 75, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 8658.5
If we take 375 away from 390, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
When dividing 150 by 75, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 8658.52
Subtracting 150 from 150 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 9:
75 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8658.52
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.

Advancing to step 10:
The number 75 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8658.52
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 final outcome is 8658.52, with a leftover of 0.0.
