We divide 636969 by 75
The aim is to understand the frequency of 75 in 636969.

Step 1:
When dividing 6 by 75, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 75

Moving on to step 2:
63 divided by 75 is 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Grab the next digit (6) from the dividend, add it to 63, then carry on: 636 / 75

Step 3:
75 goes into 636 8 times with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 600 away from 636, we end up with 36.
Include the next digit (9) from the dividend after 36, then repeat: 369 / 75

Moving on to step 4:
369 divided by 75 is 4 with a remainder of 69.
Write down 4 as next digit of the result. 
Result so far: 84.0
Deduct 300 from 369 and we're left with 69.
Include the next digit (6) from the dividend after 69, then repeat: 696 / 75

Going ahead to step 5:
The number 75 fits into 696 9 times, leaving a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 849.0
If we subtract 675 from 696, we get 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 75

On to step 6:
The number 75 fits into 219 2 times, leaving a remainder of 69.
Write down 2 as next digit of the result. 
Result so far: 8492.0
Subtract 150 from 219 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 7:
If we divide 690 by 75, we get 9 and a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 8492.9
If we subtract 675 from 690, we get 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:
75 goes into 150 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 8492.92
If we subtract 150 from 150, 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.

On to step 9:
The number 75 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8492.92
Deduct 0 from 0 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 10:
0 divided by 75 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8492.92
Subtract 0 from 0 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.

The final result is 8492.92 with a remainder of 0.0.
