330172 divided by 49 
The aim is to understand the frequency of 49 in 330172.

Step 1:
When dividing 3 by 49, we get 0 with 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.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 49

On to step 2:
49 goes into 33 0 times with a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Include the next digit (0) from the dividend after 33, then repeat: 330 / 49

On to step 3:
When dividing 330 by 49, we get 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 294 from 330 to get 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 49

On to step 4:
49 goes into 361 7 times with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 67.0
Subtracting 343 from 361 leaves us with 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 49

On to step 5:
When dividing 187 by 49, we get 3 with a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 673.0
Subtract 147 from 187 to get 40.
Include the next digit (2) from the dividend after 40, then repeat: 402 / 49

Advancing to step 6:
When dividing 402 by 49, we get 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 6738.0
If we subtract 392 from 402, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
49 goes into 100 2 times with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 6738.2
Subtract 98 from 100 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
The number 49 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 6738.2
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
When dividing 200 by 49, we get 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 6738.204
Subtracting 196 from 200 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
49 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 6738.204
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
49 can be fit into 400 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 6738.20408
Subtracting 392 from 400 leaves us 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.

Step 12:
If we divide 80 by 49, we get 1 and a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 6738.204081
Subtracting 49 from 80 leaves us 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.

On to step 13:
49 goes into 310 6 times with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 6738.2040816
Deduct 294 from 310 and we're left 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.

Step 14:
The number 49 fits into 160 3 times, leaving a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 6738.20408163
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.

Our division results in 6738.20408163 with a remaining 1.3e-08.
