78599559 ÷ 396 
The aim is to understand the frequency of 396 in 78599559.

Moving on to step 1:
396 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 396

On to step 2:
If we divide 78 by 396, we get 0 and a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Bring next digit (5) of the dividend behind the 78 and repeat the process: 785 / 396

Step 3:
396 can be fit into 785 1 times, resulting in a remainder of 389.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 389 after subtracting 396 from 785.
Bring next digit (9) of the dividend behind the 389 and repeat the process: 3899 / 396

Step 4:
The number 396 fits into 3899 9 times, leaving a remainder of 335.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 3564 from 3899 and we're left with 335.
Fetch the next digit (9) from the dividend, attach it to 335 and continue: 3359 / 396

Let's proceed to step 5:
When dividing 3359 by 396, we get 8 with a remainder of 191.
The number 8 becomes the next digit in our result. 
Result so far: 198.0
Subtract 3168 from 3359 to get 191.
Include the next digit (5) from the dividend after 191, then repeat: 1915 / 396

On to step 6:
The number 396 fits into 1915 4 times, leaving a remainder of 331.
The number 4 becomes the next digit in our result. 
Result so far: 1984.0
Subtract 1584 from 1915 to get 331.
Fetch the next digit (5) from the dividend, attach it to 331 and continue: 3315 / 396

Step 7:
396 can be fit into 3315 8 times, resulting in a remainder of 147.
Put 8 as the next digit of the answer. 
Result so far: 19848.0
Deduct 3168 from 3315 and we're left with 147.
Grab the next digit (9) from the dividend, add it to 147, then carry on: 1479 / 396

On to step 8:
396 can be fit into 1479 3 times, resulting in a remainder of 291.
Put 3 as the next digit of the answer. 
Result so far: 198483.0
If we subtract 1188 from 1479, we get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Let's proceed to step 9:
If we divide 2910 by 396, we get 7 and a remainder of 138.
Put 7 as the next digit of the answer. 
Result so far: 198483.7
If we take 2772 away from 2910, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 10:
396 can be fit into 1380 3 times, resulting in a remainder of 192.
The next digit of our result is 3. 
Result so far: 198483.73
The remainder is 192 after subtracting 1188 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 11:
396 can be fit into 1920 4 times, resulting in a remainder of 336.
Write down 4 as next digit of the result. 
Result so far: 198483.734
Subtracting 1584 from 1920 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 12:
396 goes into 3360 8 times with a remainder of 192.
Use 8 as the next digit of our solution. 
Result so far: 198483.7348
If we take 3168 away from 3360, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 13:
396 can be fit into 1920 4 times, resulting in a remainder of 336.
Use 4 as the next digit of our solution. 
Result so far: 198483.73484
Subtracting 1584 from 1920 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 14:
The number 396 fits into 3360 8 times, leaving a remainder of 192.
Use 8 as the next digit of our solution. 
Result so far: 198483.734848
Subtracting 3168 from 3360 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 15:
When dividing 1920 by 396, we get 4 with a remainder of 336.
Put 4 as the next digit of the answer. 
Result so far: 198483.7348484
Subtract 1584 from 1920 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 16:
396 can be fit into 3360 8 times, resulting in a remainder of 192.
The next digit of our result is 8. 
Result so far: 198483.73484848
The remainder is 192 after subtracting 3168 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The quotient of the division is 198483.73484848, and the remainder is 1.92e-07.
