54412158 ÷ 125 
We're looking to find how many times 125 goes into 54412158.

Moving on to step 1:
125 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 125

Let's proceed to step 2:
The number 125 fits into 54 0 times, leaving a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Include the next digit (4) from the dividend after 54, then repeat: 544 / 125

Let's proceed to step 3:
544 divided by 125 is 4 with a remainder of 44.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 500 from 544 to get 44.
Bring next digit (1) of the dividend behind the 44 and repeat the process: 441 / 125

On to step 4:
When dividing 441 by 125, we get 3 with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we take 375 away from 441, we end up with 66.
Bring next digit (2) of the dividend behind the 66 and repeat the process: 662 / 125

Let's proceed to step 5:
125 goes into 662 5 times with a remainder of 37.
Record the quotient 5 as the next digit in the result. 
Result so far: 435.0
Subtract 625 from 662 to get 37.
Append the next digit (1) from the dividend to 37 and continue with: 371 / 125

Advancing to step 6:
When dividing 371 by 125, we get 2 with a remainder of 121.
Write down 2 as next digit of the result. 
Result so far: 4352.0
If we subtract 250 from 371, we get 121.
Include the next digit (5) from the dividend after 121, then repeat: 1215 / 125

Advancing to step 7:
125 can be fit into 1215 9 times, resulting in a remainder of 90.
Put 9 as the next digit of the answer. 
Result so far: 43529.0
Subtract 1125 from 1215 to get 90.
Take the next digit (8) from the dividend and append it to 90, then repeat: 908 / 125

Step 8:
When dividing 908 by 125, we get 7 with a remainder of 33.
The next digit of our result is 7. 
Result so far: 435297.0
If we subtract 875 from 908, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 9:
When dividing 330 by 125, we get 2 with a remainder of 80.
The next digit of our result is 2. 
Result so far: 435297.2
If we subtract 250 from 330, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
125 goes into 800 6 times with a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 435297.26
Deduct 750 from 800 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
If we divide 500 by 125, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 435297.264
If we subtract 500 from 500, we get 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 12:
When dividing 0 by 125, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 435297.264
Subtracting 0 from 0 leaves us 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.

On to step 13:
0 divided by 125 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 435297.264
Subtract 0 from 0 to get 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 435297.264, with a leftover of 0.0.
