48213501 ÷ 49 
The aim is to understand the frequency of 49 in 48213501.

On to step 1:
49 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 49

Moving on to step 2:
When dividing 48 by 49, we get 0 with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Include the next digit (2) from the dividend after 48, then repeat: 482 / 49

Going ahead to step 3:
49 goes into 482 9 times with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 41 after subtracting 441 from 482.
Take the next digit (1) from the dividend and append it to 41, then repeat: 411 / 49

Going ahead to step 4:
If we divide 411 by 49, we get 8 and a remainder of 19.
The next digit of our result is 8. 
Result so far: 98.0
Deduct 392 from 411 and we're left with 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 49

Advancing to step 5:
The number 49 fits into 193 3 times, leaving a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 983.0
If we take 147 away from 193, we end up with 46.
Take the next digit (5) from the dividend and append it to 46, then repeat: 465 / 49

Let's proceed to step 6:
49 can be fit into 465 9 times, resulting in a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 9839.0
Subtracting 441 from 465 leaves us with 24.
Include the next digit (0) from the dividend after 24, then repeat: 240 / 49

Going ahead to step 7:
49 can be fit into 240 4 times, resulting in a remainder of 44.
The next digit of our result is 4. 
Result so far: 98394.0
Subtracting 196 from 240 leaves us with 44.
Take the next digit (1) from the dividend and append it to 44, then repeat: 441 / 49

Let's proceed to step 8:
441 divided by 49 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 983949.0
If we take 441 away from 441, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
The number 49 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 983949.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
49 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 983949.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 983949.0 with a remainder of 0.0.
