We look at the division of 81575680 by 996 
The aim is to understand the frequency of 996 in 81575680.

Going ahead to step 1:
The number 996 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 996

Let's proceed to step 2:
996 goes into 81 0 times with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Append the next digit (5) from the dividend to 81 and continue with: 815 / 996

Step 3:
If we divide 815 by 996, we get 0 and a remainder of 815.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 815, we end up with 815.
Include the next digit (7) from the dividend after 815, then repeat: 8157 / 996

Moving on to step 4:
996 goes into 8157 8 times with a remainder of 189.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 189 after subtracting 7968 from 8157.
Bring next digit (5) of the dividend behind the 189 and repeat the process: 1895 / 996

Let's proceed to step 5:
996 goes into 1895 1 times with a remainder of 899.
The next digit of our result is 1. 
Result so far: 81.0
Deduct 996 from 1895 and we're left with 899.
Append the next digit (6) from the dividend to 899 and continue with: 8996 / 996

Let's proceed to step 6:
The number 996 fits into 8996 9 times, leaving a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 819.0
The remainder is 32 after subtracting 8964 from 8996.
Take the next digit (8) from the dividend and append it to 32, then repeat: 328 / 996

Let's proceed to step 7:
The number 996 fits into 328 0 times, leaving a remainder of 328.
The number 0 becomes the next digit in our result. 
Result so far: 8190.0
Subtracting 0 from 328 leaves us with 328.
Grab the next digit (0) from the dividend, add it to 328, then carry on: 3280 / 996

Step 8:
996 can be fit into 3280 3 times, resulting in a remainder of 292.
The next digit of our result is 3. 
Result so far: 81903.0
The remainder is 292 after subtracting 2988 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 9:
When dividing 2920 by 996, we get 2 with a remainder of 928.
The number 2 becomes the next digit in our result. 
Result so far: 81903.2
Subtract 1992 from 2920 to get 928.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9280, and continue the process.

On to step 10:
The number 996 fits into 9280 9 times, leaving a remainder of 316.
Record the quotient 9 as the next digit in the result. 
Result so far: 81903.29
Deduct 8964 from 9280 and we're left with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 11:
The number 996 fits into 3160 3 times, leaving a remainder of 172.
Put 3 as the next digit of the answer. 
Result so far: 81903.293
Subtracting 2988 from 3160 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 12:
996 can be fit into 1720 1 times, resulting in a remainder of 724.
Use 1 as the next digit of our solution. 
Result so far: 81903.2931
Subtracting 996 from 1720 leaves us with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Advancing to step 13:
When dividing 7240 by 996, we get 7 with a remainder of 268.
The number 7 becomes the next digit in our result. 
Result so far: 81903.29317
If we subtract 6972 from 7240, we get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 14:
996 goes into 2680 2 times with a remainder of 688.
The number 2 becomes the next digit in our result. 
Result so far: 81903.293172
Subtracting 1992 from 2680 leaves us with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Step 15:
6880 divided by 996 is 6 with a remainder of 904.
The next digit of our result is 6. 
Result so far: 81903.2931726
If we subtract 5976 from 6880, we get 904.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9040, and continue the process.

Advancing to step 16:
996 goes into 9040 9 times with a remainder of 76.
Record the quotient 9 as the next digit in the result. 
Result so far: 81903.29317269
If we take 8964 away from 9040, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

In conclusion, the division gives 81903.29317269 with a balance of 7.6e-08.
