We look at the division of 41391631 by 49 
The aim is to understand the frequency of 49 in 41391631.

Let's proceed to step 1:
The number 49 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 49

On to step 2:
When dividing 41 by 49, we get 0 with a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Include the next digit (3) from the dividend after 41, then repeat: 413 / 49

Advancing to step 3:
49 can be fit into 413 8 times, resulting in a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 392 from 413 leaves us with 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 49

Let's proceed to step 4:
219 divided by 49 is 4 with a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 84.0
If we subtract 196 from 219, we get 23.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 49

Going ahead to step 5:
The number 49 fits into 231 4 times, leaving a remainder of 35.
Record the quotient 4 as the next digit in the result. 
Result so far: 844.0
Deduct 196 from 231 and we're left with 35.
Fetch the next digit (6) from the dividend, attach it to 35 and continue: 356 / 49

On to step 6:
If we divide 356 by 49, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 8447.0
Subtracting 343 from 356 leaves us with 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 49

Advancing to step 7:
The number 49 fits into 133 2 times, leaving a remainder of 35.
Write down 2 as next digit of the result. 
Result so far: 84472.0
Deduct 98 from 133 and we're left with 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 49

Let's proceed to step 8:
If we divide 351 by 49, we get 7 and a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 844727.0
Deduct 343 from 351 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.

Step 9:
49 goes into 80 1 times with a remainder of 31.
The next digit of our result is 1. 
Result so far: 844727.1
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.

Step 10:
The number 49 fits into 310 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 844727.16
If we take 294 away from 310, we end up 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.

Advancing to step 11:
49 can be fit into 160 3 times, resulting in a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 844727.163
If we take 147 away from 160, we end up 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.

Moving on to step 12:
When dividing 130 by 49, we get 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 844727.1632
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 13:
The number 49 fits into 320 6 times, leaving a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 844727.16326
If we take 294 away from 320, we end up 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.

Going ahead to step 14:
When dividing 260 by 49, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 844727.163265
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.

Moving on to step 15:
The number 49 fits into 150 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 844727.1632653
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 16:
When dividing 30 by 49, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 844727.1632653
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 844727.1632653 with a remainder of 3e-08.
