609863 divided by 75 
The aim is to understand the frequency of 75 in 609863.

Going ahead to step 1:
If we divide 6 by 75, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 75

Let's proceed to step 2:
The number 75 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 60, we get 60.
Bring next digit (9) of the dividend behind the 60 and repeat the process: 609 / 75

Advancing to step 3:
The number 75 fits into 609 8 times, leaving a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 600 from 609 and we're left with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 75

On to step 4:
75 goes into 98 1 times with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 81.0
Deduct 75 from 98 and we're left with 23.
Append the next digit (6) from the dividend to 23 and continue with: 236 / 75

On to step 5:
236 divided by 75 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 813.0
Deduct 225 from 236 and we're left with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 75

On to step 6:
If we divide 113 by 75, we get 1 and a remainder of 38.
The next digit of our result is 1. 
Result so far: 8131.0
If we subtract 75 from 113, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 7:
75 goes into 380 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 8131.5
If we subtract 375 from 380, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
75 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 8131.5
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
The number 75 fits into 500 6 times, leaving a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 8131.506
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
500 divided by 75 is 6 with a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 8131.5066
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 8131.5066, and the remainder is 0.0005.
