We look at the division of 54572437 by 48 
We're looking to find how many times 48 goes into 54572437.

Step 1:
5 divided by 48 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 48

Going ahead to step 2:
54 divided by 48 is 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 48 from 54 to get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 48

Advancing to step 3:
The number 48 fits into 65 1 times, leaving a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 48 from 65 to get 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 48

Moving on to step 4:
48 can be fit into 177 3 times, resulting in a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 113.0
If we take 144 away from 177, we end up with 33.
Include the next digit (2) from the dividend after 33, then repeat: 332 / 48

Let's proceed to step 5:
332 divided by 48 is 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 1136.0
Subtracting 288 from 332 leaves us with 44.
Append the next digit (4) from the dividend to 44 and continue with: 444 / 48

Step 6:
If we divide 444 by 48, we get 9 and a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 11369.0
Subtracting 432 from 444 leaves us with 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 48

Advancing to step 7:
When dividing 123 by 48, we get 2 with a remainder of 27.
The number 2 becomes the next digit in our result. 
Result so far: 113692.0
If we take 96 away from 123, we end up with 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 48

Let's proceed to step 8:
48 goes into 277 5 times with a remainder of 37.
The next digit of our result is 5. 
Result so far: 1136925.0
Deduct 240 from 277 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 9:
When dividing 370 by 48, we get 7 with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 1136925.7
Subtract 336 from 370 to 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 10:
The number 48 fits into 340 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 1136925.77
If we subtract 336 from 340, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 1136925.77, with a leftover of 0.004.
