Let's divide 64216220 by 975
The aim is to understand the frequency of 975 in 64216220.

Going ahead to step 1:
If we divide 6 by 975, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 975

Going ahead to step 2:
64 divided by 975 is 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Append the next digit (2) from the dividend to 64 and continue with: 642 / 975

Advancing to step 3:
The number 975 fits into 642 0 times, leaving a remainder of 642.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 642 and we're left with 642.
Append the next digit (1) from the dividend to 642 and continue with: 6421 / 975

Going ahead to step 4:
975 can be fit into 6421 6 times, resulting in a remainder of 571.
The next digit of our result is 6. 
Result so far: 6.0
If we take 5850 away from 6421, we end up with 571.
Include the next digit (6) from the dividend after 571, then repeat: 5716 / 975

Advancing to step 5:
When dividing 5716 by 975, we get 5 with a remainder of 841.
The next digit of our result is 5. 
Result so far: 65.0
The remainder is 841 after subtracting 4875 from 5716.
Append the next digit (2) from the dividend to 841 and continue with: 8412 / 975

Step 6:
8412 divided by 975 is 8 with a remainder of 612.
Use 8 as the next digit of our solution. 
Result so far: 658.0
Subtracting 7800 from 8412 leaves us with 612.
Include the next digit (2) from the dividend after 612, then repeat: 6122 / 975

Advancing to step 7:
975 can be fit into 6122 6 times, resulting in a remainder of 272.
Write down 6 as next digit of the result. 
Result so far: 6586.0
If we subtract 5850 from 6122, we get 272.
Bring next digit (0) of the dividend behind the 272 and repeat the process: 2720 / 975

Step 8:
The number 975 fits into 2720 2 times, leaving a remainder of 770.
The next digit of our result is 2. 
Result so far: 65862.0
The remainder is 770 after subtracting 1950 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Step 9:
975 goes into 7700 7 times with a remainder of 875.
Write down 7 as next digit of the result. 
Result so far: 65862.7
If we subtract 6825 from 7700, we get 875.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8750, and continue the process.

Step 10:
The number 975 fits into 8750 8 times, leaving a remainder of 950.
The next digit of our result is 8. 
Result so far: 65862.78
Subtracting 7800 from 8750 leaves us 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.

Step 11:
9500 divided by 975 is 9 with a remainder of 725.
Record the quotient 9 as the next digit in the result. 
Result so far: 65862.789
Subtracting 8775 from 9500 leaves us with 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Moving on to step 12:
When dividing 7250 by 975, we get 7 with a remainder of 425.
Record the quotient 7 as the next digit in the result. 
Result so far: 65862.7897
If we take 6825 away from 7250, we end up 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.

Moving on to step 13:
975 goes into 4250 4 times with a remainder of 350.
Record the quotient 4 as the next digit in the result. 
Result so far: 65862.78974
Subtracting 3900 from 4250 leaves us 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.

Step 14:
The number 975 fits into 3500 3 times, leaving a remainder of 575.
The number 3 becomes the next digit in our result. 
Result so far: 65862.789743
If we take 2925 away from 3500, we end up with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Moving on to step 15:
5750 divided by 975 is 5 with a remainder of 875.
Put 5 as the next digit of the answer. 
Result so far: 65862.7897435
Subtracting 4875 from 5750 leaves us 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.

Moving on to step 16:
975 goes into 8750 8 times with a remainder of 950.
Use 8 as the next digit of our solution. 
Result so far: 65862.78974358
The remainder is 950 after subtracting 7800 from 8750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9500, and continue the process.

After the division, we end up with 65862.78974358 and a remainder of 9.5e-07.
