We look at the division of 16618604 by 49 
The aim is to understand the frequency of 49 in 16618604.

Step 1:
49 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 49

Going ahead to step 2:
The number 49 fits into 16 0 times, leaving a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 49

Let's proceed to step 3:
The number 49 fits into 166 3 times, leaving a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 147 from 166, we get 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 49

Step 4:
If we divide 191 by 49, we get 3 and a remainder of 44.
The next digit of our result is 3. 
Result so far: 33.0
Deduct 147 from 191 and we're left with 44.
Fetch the next digit (8) from the dividend, attach it to 44 and continue: 448 / 49

Let's proceed to step 5:
49 can be fit into 448 9 times, resulting in a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 339.0
The remainder is 7 after subtracting 441 from 448.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 49

Step 6:
The number 49 fits into 76 1 times, leaving a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 3391.0
If we take 49 away from 76, we end up with 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 49

On to step 7:
If we divide 270 by 49, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 33915.0
Deduct 245 from 270 and we're left with 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 49

Step 8:
49 can be fit into 254 5 times, resulting in a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 339155.0
If we subtract 245 from 254, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
49 can be fit into 90 1 times, resulting in a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 339155.1
Deduct 49 from 90 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 10:
The number 49 fits into 410 8 times, leaving a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 339155.18
Subtract 392 from 410 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
If we divide 180 by 49, we get 3 and a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 339155.183
The remainder is 33 after subtracting 147 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 12:
If we divide 330 by 49, we get 6 and a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 339155.1836
Deduct 294 from 330 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
When dividing 360 by 49, we get 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 339155.18367
The remainder is 17 after subtracting 343 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 14:
49 goes into 170 3 times with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 339155.183673
If we take 147 away from 170, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 15:
When dividing 230 by 49, we get 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 339155.1836734
If we subtract 196 from 230, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 16:
49 can be fit into 340 6 times, resulting in a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 339155.18367346
Deduct 294 from 340 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 339155.18367346, with a leftover of 4.6e-08.
