We're dividing 72844331 by 975 
The aim is to understand the frequency of 975 in 72844331.

Advancing to step 1:
The number 975 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 975

Going ahead to step 2:
When dividing 72 by 975, we get 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Take the next digit (8) from the dividend and append it to 72, then repeat: 728 / 975

Advancing to step 3:
975 goes into 728 0 times with a remainder of 728.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 728 leaves us with 728.
Take the next digit (4) from the dividend and append it to 728, then repeat: 7284 / 975

Moving on to step 4:
975 can be fit into 7284 7 times, resulting in a remainder of 459.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 6825 from 7284 leaves us with 459.
Include the next digit (4) from the dividend after 459, then repeat: 4594 / 975

Moving on to step 5:
975 can be fit into 4594 4 times, resulting in a remainder of 694.
Write down 4 as next digit of the result. 
Result so far: 74.0
Subtracting 3900 from 4594 leaves us with 694.
Fetch the next digit (3) from the dividend, attach it to 694 and continue: 6943 / 975

Advancing to step 6:
If we divide 6943 by 975, we get 7 and a remainder of 118.
Use 7 as the next digit of our solution. 
Result so far: 747.0
If we take 6825 away from 6943, we end up with 118.
Grab the next digit (3) from the dividend, add it to 118, then carry on: 1183 / 975

Moving on to step 7:
1183 divided by 975 is 1 with a remainder of 208.
The next digit of our result is 1. 
Result so far: 7471.0
If we subtract 975 from 1183, we get 208.
Grab the next digit (1) from the dividend, add it to 208, then carry on: 2081 / 975

On to step 8:
If we divide 2081 by 975, we get 2 and a remainder of 131.
The next digit of our result is 2. 
Result so far: 74712.0
Subtracting 1950 from 2081 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 9:
975 can be fit into 1310 1 times, resulting in a remainder of 335.
Write down 1 as next digit of the result. 
Result so far: 74712.1
Subtracting 975 from 1310 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 10:
When dividing 3350 by 975, we get 3 with a remainder of 425.
Record the quotient 3 as the next digit in the result. 
Result so far: 74712.13
Deduct 2925 from 3350 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Going ahead to step 11:
4250 divided by 975 is 4 with a remainder of 350.
Use 4 as the next digit of our solution. 
Result so far: 74712.134
Deduct 3900 from 4250 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 12:
975 goes into 3500 3 times with a remainder of 575.
The next digit of our result is 3. 
Result so far: 74712.1343
Subtract 2925 from 3500 to get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Step 13:
975 goes into 5750 5 times with a remainder of 875.
Write down 5 as next digit of the result. 
Result so far: 74712.13435
If we take 4875 away from 5750, we end up with 875.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8750, and continue the process.

On to step 14:
8750 divided by 975 is 8 with a remainder of 950.
The next digit of our result is 8. 
Result so far: 74712.134358
If we take 7800 away from 8750, we end up with 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9500, and continue the process.

Let's proceed to step 15:
975 can be fit into 9500 9 times, resulting in a remainder of 725.
Put 9 as the next digit of the answer. 
Result so far: 74712.1343589
If we subtract 8775 from 9500, we get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

On to step 16:
When dividing 7250 by 975, we get 7 with a remainder of 425.
Write down 7 as next digit of the result. 
Result so far: 74712.13435897
Subtract 6825 from 7250 to get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

The final result is 74712.13435897 with a remainder of 4.25e-07.
