We look at the division of 870390 by 96 
The aim is to understand the frequency of 96 in 870390.

Moving on to step 1:
The number 96 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 96

Moving on to step 2:
The number 96 fits into 87 0 times, leaving a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Include the next digit (0) from the dividend after 87, then repeat: 870 / 96

Moving on to step 3:
96 can be fit into 870 9 times, resulting in a remainder of 6.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 864 from 870 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 96

Let's proceed to step 4:
63 divided by 96 is 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 90.0
Subtract 0 from 63 to get 63.
Fetch the next digit (9) from the dividend, attach it to 63 and continue: 639 / 96

Step 5:
When dividing 639 by 96, we get 6 with a remainder of 63.
Use 6 as the next digit of our solution. 
Result so far: 906.0
If we take 576 away from 639, we end up with 63.
Grab the next digit (0) from the dividend, add it to 63, then carry on: 630 / 96

Going ahead to step 6:
The number 96 fits into 630 6 times, leaving a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 9066.0
Deduct 576 from 630 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 7:
96 goes into 540 5 times with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 9066.5
The remainder is 60 after subtracting 480 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
When dividing 600 by 96, we get 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 9066.56
Subtracting 576 from 600 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
240 divided by 96 is 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 9066.562
If we take 192 away from 240, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
If we divide 480 by 96, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 9066.5625
Subtracting 480 from 480 leaves us 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.

Let's proceed to step 11:
If we divide 0 by 96, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9066.5625
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.

Step 12:
The number 96 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9066.5625
If we take 0 away from 0, we end up 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.

The final result is 9066.5625 with a remainder of 0.0.
