Let's divide 75259053 by 975
The aim is to understand the frequency of 975 in 75259053.

Advancing to step 1:
7 divided by 975 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 975

Moving on to step 2:
975 can be fit into 75 0 times, resulting in a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Bring next digit (2) of the dividend behind the 75 and repeat the process: 752 / 975

On to step 3:
752 divided by 975 is 0 with a remainder of 752.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 752 after subtracting 0 from 752.
Append the next digit (5) from the dividend to 752 and continue with: 7525 / 975

Advancing to step 4:
975 goes into 7525 7 times with a remainder of 700.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 700 after subtracting 6825 from 7525.
Include the next digit (9) from the dividend after 700, then repeat: 7009 / 975

Going ahead to step 5:
7009 divided by 975 is 7 with a remainder of 184.
Write down 7 as next digit of the result. 
Result so far: 77.0
Subtracting 6825 from 7009 leaves us with 184.
Fetch the next digit (0) from the dividend, attach it to 184 and continue: 1840 / 975

Let's proceed to step 6:
1840 divided by 975 is 1 with a remainder of 865.
Record the quotient 1 as the next digit in the result. 
Result so far: 771.0
Deduct 975 from 1840 and we're left with 865.
Bring next digit (5) of the dividend behind the 865 and repeat the process: 8655 / 975

Moving on to step 7:
If we divide 8655 by 975, we get 8 and a remainder of 855.
Put 8 as the next digit of the answer. 
Result so far: 7718.0
If we subtract 7800 from 8655, we get 855.
Take the next digit (3) from the dividend and append it to 855, then repeat: 8553 / 975

Advancing to step 8:
If we divide 8553 by 975, we get 8 and a remainder of 753.
The next digit of our result is 8. 
Result so far: 77188.0
The remainder is 753 after subtracting 7800 from 8553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7530, and continue the process.

Moving on to step 9:
When dividing 7530 by 975, we get 7 with a remainder of 705.
Write down 7 as next digit of the result. 
Result so far: 77188.7
Deduct 6825 from 7530 and we're left with 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Let's proceed to step 10:
975 can be fit into 7050 7 times, resulting in a remainder of 225.
The next digit of our result is 7. 
Result so far: 77188.77
If we subtract 6825 from 7050, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

The final result is 77188.77 with a remainder of 0.225.
