We look at the division of 971824 by 49 
The aim is to understand the frequency of 49 in 971824.

Going ahead to step 1:
49 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 49

Advancing to step 2:
When dividing 97 by 49, we get 1 with a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 49 from 97 and we're left with 48.
Take the next digit (1) from the dividend and append it to 48, then repeat: 481 / 49

Advancing to step 3:
49 goes into 481 9 times with a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 40 after subtracting 441 from 481.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 49

Moving on to step 4:
When dividing 408 by 49, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 198.0
Subtract 392 from 408 to get 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 49

Let's proceed to step 5:
When dividing 162 by 49, we get 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 1983.0
Subtracting 147 from 162 leaves us with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 49

Let's proceed to step 6:
49 goes into 154 3 times with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 19833.0
Subtract 147 from 154 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
49 goes into 70 1 times with a remainder of 21.
The next digit of our result is 1. 
Result so far: 19833.1
If we take 49 away from 70, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 8:
49 goes into 210 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 19833.14
Subtracting 196 from 210 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
When dividing 140 by 49, we get 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 19833.142
If we subtract 98 from 140, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
420 divided by 49 is 8 with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 19833.1428
If we subtract 392 from 420, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
When dividing 280 by 49, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 19833.14285
Deduct 245 from 280 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
350 divided by 49 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 19833.142857
If we subtract 343 from 350, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 13:
49 can be fit into 70 1 times, resulting in a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 19833.1428571
Subtracting 49 from 70 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 14:
210 divided by 49 is 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 19833.14285714
The remainder is 14 after subtracting 196 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 19833.14285714 with a remaining 1.4e-08.
