We're dividing 54129 by 73 
We're looking to find how many times 73 goes into 54129.

Step 1:
When dividing 5 by 73, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 73

Let's proceed to step 2:
73 goes into 54 0 times with a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Append the next digit (1) from the dividend to 54 and continue with: 541 / 73

Advancing to step 3:
541 divided by 73 is 7 with a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 511 from 541, we get 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 73

Moving on to step 4:
When dividing 302 by 73, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 74.0
Subtract 292 from 302 to get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 73

Let's proceed to step 5:
109 divided by 73 is 1 with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 741.0
The remainder is 36 after subtracting 73 from 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 6:
73 goes into 360 4 times with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 741.4
Deduct 292 from 360 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 7:
73 can be fit into 680 9 times, resulting in a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 741.49
Deduct 657 from 680 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 8:
73 can be fit into 230 3 times, resulting in a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 741.493
Deduct 219 from 230 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
73 can be fit into 110 1 times, resulting in a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 741.4931
The remainder is 37 after subtracting 73 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 10:
When dividing 370 by 73, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 741.49315
Deduct 365 from 370 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
73 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 741.49315
The remainder is 50 after subtracting 0 from 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 12:
500 divided by 73 is 6 with a remainder of 62.
The next digit of our result is 6. 
Result so far: 741.4931506
If we take 438 away from 500, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 13:
73 can be fit into 620 8 times, resulting in a remainder of 36.
The next digit of our result is 8. 
Result so far: 741.49315068
If we subtract 584 from 620, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 741.49315068 with a remainder of 3.6e-08.
