54339119 ÷ 125 
We want to figure out the number of times 54339119 can be divided by 125.

Moving on to step 1:
When dividing 5 by 125, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
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 / 125

Advancing to step 2:
125 goes into 54 0 times with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 125

On to step 3:
543 divided by 125 is 4 with a remainder of 43.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 500 from 543 and we're left with 43.
Fetch the next digit (3) from the dividend, attach it to 43 and continue: 433 / 125

Let's proceed to step 4:
If we divide 433 by 125, we get 3 and a remainder of 58.
Put 3 as the next digit of the answer. 
Result so far: 43.0
The remainder is 58 after subtracting 375 from 433.
Grab the next digit (9) from the dividend, add it to 58, then carry on: 589 / 125

Step 5:
589 divided by 125 is 4 with a remainder of 89.
The number 4 becomes the next digit in our result. 
Result so far: 434.0
The remainder is 89 after subtracting 500 from 589.
Include the next digit (1) from the dividend after 89, then repeat: 891 / 125

On to step 6:
If we divide 891 by 125, we get 7 and a remainder of 16.
The next digit of our result is 7. 
Result so far: 4347.0
If we subtract 875 from 891, we get 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 125

Let's proceed to step 7:
When dividing 161 by 125, we get 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 43471.0
Subtract 125 from 161 to get 36.
Take the next digit (9) from the dividend and append it to 36, then repeat: 369 / 125

Going ahead to step 8:
369 divided by 125 is 2 with a remainder of 119.
Record the quotient 2 as the next digit in the result. 
Result so far: 434712.0
Subtracting 250 from 369 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Let's proceed to step 9:
125 can be fit into 1190 9 times, resulting in a remainder of 65.
Put 9 as the next digit of the answer. 
Result so far: 434712.9
If we subtract 1125 from 1190, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 10:
When dividing 650 by 125, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 434712.95
Deduct 625 from 650 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
125 can be fit into 250 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 434712.952
If we subtract 250 from 250, 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:
The number 125 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 434712.952
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.

Let's proceed 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: 434712.952
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.

The quotient of the division is 434712.952, and the remainder is 0.0.
