396891 ÷ 49 
The aim is to understand the frequency of 49 in 396891.

Let's proceed to step 1:
49 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 49

Step 2:
If we divide 39 by 49, we get 0 and a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Append the next digit (6) from the dividend to 39 and continue with: 396 / 49

Let's proceed to step 3:
If we divide 396 by 49, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 392 from 396, we get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 49

Step 4:
The number 49 fits into 48 0 times, leaving a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Subtract 0 from 48 to get 48.
Append the next digit (9) from the dividend to 48 and continue with: 489 / 49

Let's proceed to step 5:
If we divide 489 by 49, we get 9 and a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 809.0
The remainder is 48 after subtracting 441 from 489.
Take the next digit (1) from the dividend and append it to 48, then repeat: 481 / 49

On to step 6:
If we divide 481 by 49, we get 9 and a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 8099.0
If we subtract 441 from 481, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
49 goes into 400 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 8099.8
Deduct 392 from 400 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
49 can be fit into 80 1 times, resulting in a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 8099.81
Deduct 49 from 80 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
49 goes into 310 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 8099.816
If we subtract 294 from 310, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
49 goes into 160 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 8099.8163
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
If we divide 130 by 49, we get 2 and a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 8099.81632
If we take 98 away from 130, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
49 can be fit into 320 6 times, resulting in a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 8099.816326
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 13:
When dividing 260 by 49, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 8099.8163265
If we subtract 245 from 260, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
When dividing 150 by 49, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 8099.81632653
If we take 147 away from 150, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 8099.81632653 with a balance of 3e-09.
