We're dividing 8219936 by 975 
The aim is to understand the frequency of 975 in 8219936.

Going ahead to step 1:
8 divided by 975 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 975

Going ahead to step 2:
If we divide 82 by 975, we get 0 and a remainder of 82.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 82, we get 82.
Take the next digit (1) from the dividend and append it to 82, then repeat: 821 / 975

On to step 3:
821 divided by 975 is 0 with a remainder of 821.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 821 leaves us with 821.
Include the next digit (9) from the dividend after 821, then repeat: 8219 / 975

Going ahead to step 4:
If we divide 8219 by 975, we get 8 and a remainder of 419.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 7800 from 8219 and we're left with 419.
Grab the next digit (9) from the dividend, add it to 419, then carry on: 4199 / 975

Moving on to step 5:
The number 975 fits into 4199 4 times, leaving a remainder of 299.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
Subtracting 3900 from 4199 leaves us with 299.
Take the next digit (3) from the dividend and append it to 299, then repeat: 2993 / 975

Let's proceed to step 6:
When dividing 2993 by 975, we get 3 with a remainder of 68.
The next digit of our result is 3. 
Result so far: 843.0
Subtract 2925 from 2993 to get 68.
Fetch the next digit (6) from the dividend, attach it to 68 and continue: 686 / 975

Advancing to step 7:
975 can be fit into 686 0 times, resulting in a remainder of 686.
Use 0 as the next digit of our solution. 
Result so far: 8430.0
If we subtract 0 from 686, we get 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Going ahead to step 8:
975 can be fit into 6860 7 times, resulting in a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 8430.7
Subtracting 6825 from 6860 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
The number 975 fits into 350 0 times, leaving a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 8430.7
Deduct 0 from 350 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.

Let's proceed to step 10:
The number 975 fits into 3500 3 times, leaving a remainder of 575.
Put 3 as the next digit of the answer. 
Result so far: 8430.703
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.

Let's proceed to step 11:
975 can be fit into 5750 5 times, resulting in a remainder of 875.
The next digit of our result is 5. 
Result so far: 8430.7035
Deduct 4875 from 5750 and we're left 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.

Let's proceed to step 12:
If we divide 8750 by 975, we get 8 and a remainder of 950.
Use 8 as the next digit of our solution. 
Result so far: 8430.70358
Subtract 7800 from 8750 to get 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9500, and continue the process.

Moving on to step 13:
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: 8430.703589
Deduct 8775 from 9500 and we're left 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.

On to step 14:
975 goes into 7250 7 times with a remainder of 425.
Record the quotient 7 as the next digit in the result. 
Result so far: 8430.7035897
Subtracting 6825 from 7250 leaves us 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 15:
If we divide 4250 by 975, we get 4 and a remainder of 350.
The number 4 becomes the next digit in our result. 
Result so far: 8430.70358974
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.

The final outcome is 8430.70358974, with a leftover of 3.5e-07.
