Let's divide 81534320 by 396
The aim is to understand the frequency of 396 in 81534320.

On to step 1:
396 goes into 8 0 times with 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.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 396

Let's proceed to step 2:
81 divided by 396 is 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Grab the next digit (5) from the dividend, add it to 81, then carry on: 815 / 396

Let's proceed to step 3:
The number 396 fits into 815 2 times, leaving a remainder of 23.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 792 from 815 and we're left with 23.
Include the next digit (3) from the dividend after 23, then repeat: 233 / 396

Let's proceed to step 4:
396 can be fit into 233 0 times, resulting in a remainder of 233.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 233 to get 233.
Bring next digit (4) of the dividend behind the 233 and repeat the process: 2334 / 396

Step 5:
When dividing 2334 by 396, we get 5 with a remainder of 354.
The next digit of our result is 5. 
Result so far: 205.0
If we subtract 1980 from 2334, we get 354.
Include the next digit (3) from the dividend after 354, then repeat: 3543 / 396

Let's proceed to step 6:
3543 divided by 396 is 8 with a remainder of 375.
Put 8 as the next digit of the answer. 
Result so far: 2058.0
The remainder is 375 after subtracting 3168 from 3543.
Append the next digit (2) from the dividend to 375 and continue with: 3752 / 396

Going ahead to step 7:
The number 396 fits into 3752 9 times, leaving a remainder of 188.
The next digit of our result is 9. 
Result so far: 20589.0
Subtract 3564 from 3752 to get 188.
Append the next digit (0) from the dividend to 188 and continue with: 1880 / 396

On to step 8:
When dividing 1880 by 396, we get 4 with a remainder of 296.
The number 4 becomes the next digit in our result. 
Result so far: 205894.0
Deduct 1584 from 1880 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 9:
If we divide 2960 by 396, we get 7 and a remainder of 188.
The number 7 becomes the next digit in our result. 
Result so far: 205894.7
If we take 2772 away from 2960, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 10:
396 can be fit into 1880 4 times, resulting in a remainder of 296.
Write down 4 as next digit of the result. 
Result so far: 205894.74
If we subtract 1584 from 1880, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 11:
The number 396 fits into 2960 7 times, leaving a remainder of 188.
The number 7 becomes the next digit in our result. 
Result so far: 205894.747
If we subtract 2772 from 2960, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 12:
If we divide 1880 by 396, we get 4 and a remainder of 296.
Write down 4 as next digit of the result. 
Result so far: 205894.7474
If we take 1584 away from 1880, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 13:
The number 396 fits into 2960 7 times, leaving a remainder of 188.
Put 7 as the next digit of the answer. 
Result so far: 205894.74747
If we subtract 2772 from 2960, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 14:
The number 396 fits into 1880 4 times, leaving a remainder of 296.
Use 4 as the next digit of our solution. 
Result so far: 205894.747474
If we take 1584 away from 1880, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 15:
If we divide 2960 by 396, we get 7 and a remainder of 188.
Record the quotient 7 as the next digit in the result. 
Result so far: 205894.7474747
Deduct 2772 from 2960 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 16:
When dividing 1880 by 396, we get 4 with a remainder of 296.
Use 4 as the next digit of our solution. 
Result so far: 205894.74747474
Subtracting 1584 from 1880 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

In conclusion, the division gives 205894.74747474 with a balance of 2.96e-07.
