39621141 ÷ 48 
The aim is to understand the frequency of 48 in 39621141.

Advancing to step 1:
48 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 48

Going ahead to step 2:
If we divide 39 by 48, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (6) from the dividend to 39 and continue with: 396 / 48

Going ahead to step 3:
48 goes into 396 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 12 after subtracting 384 from 396.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 48

Step 4:
The number 48 fits into 122 2 times, leaving a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 82.0
The remainder is 26 after subtracting 96 from 122.
Include the next digit (1) from the dividend after 26, then repeat: 261 / 48

Let's proceed to step 5:
48 can be fit into 261 5 times, resulting in a remainder of 21.
The number 5 becomes the next digit in our result. 
Result so far: 825.0
Deduct 240 from 261 and we're left with 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 48

Let's proceed to step 6:
If we divide 211 by 48, we get 4 and a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 8254.0
The remainder is 19 after subtracting 192 from 211.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 48

Going ahead to step 7:
48 can be fit into 194 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 82544.0
The remainder is 2 after subtracting 192 from 194.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 48

On to step 8:
The number 48 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 825440.0
If we subtract 0 from 21, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
210 divided by 48 is 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 825440.4
Deduct 192 from 210 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
The number 48 fits into 180 3 times, leaving a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 825440.43
The remainder is 36 after subtracting 144 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
48 can be fit into 360 7 times, resulting in a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 825440.437
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
If we divide 240 by 48, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 825440.4375
If we take 240 away from 240, 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.

Moving on to step 13:
The number 48 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 825440.4375
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.

Advancing to step 14:
48 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 825440.4375
Deduct 0 from 0 and we're left 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 outcome is 825440.4375, with a leftover of 0.0.
