We're dividing 817238 by 49 
The aim is to understand the frequency of 49 in 817238.

Step 1:
When dividing 8 by 49, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 49

Moving on to step 2:
If we divide 81 by 49, we get 1 and a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 32 after subtracting 49 from 81.
Take the next digit (7) from the dividend and append it to 32, then repeat: 327 / 49

Step 3:
If we divide 327 by 49, we get 6 and a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 294 away from 327, we end up with 33.
Bring next digit (2) of the dividend behind the 33 and repeat the process: 332 / 49

Moving on to step 4:
The number 49 fits into 332 6 times, leaving a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 166.0
The remainder is 38 after subtracting 294 from 332.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 49

Let's proceed to step 5:
49 can be fit into 383 7 times, resulting in a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 1667.0
The remainder is 40 after subtracting 343 from 383.
Fetch the next digit (8) from the dividend, attach it to 40 and continue: 408 / 49

Let's proceed to step 6:
408 divided by 49 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 16678.0
Subtracting 392 from 408 leaves us with 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 7:
49 goes into 160 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 16678.3
Deduct 147 from 160 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 8:
130 divided by 49 is 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 16678.32
Subtracting 98 from 130 leaves us 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 9:
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: 16678.326
Deduct 294 from 320 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
The number 49 fits into 260 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 16678.3265
If we take 245 away from 260, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
49 goes into 150 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 16678.32653
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.

Step 12:
The number 49 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 16678.32653
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
49 can be fit into 300 6 times, resulting in a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 16678.3265306
Deduct 294 from 300 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
The number 49 fits into 60 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 16678.32653061
Deduct 49 from 60 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

In conclusion, the division gives 16678.32653061 with a balance of 1.1e-08.
