Let's divide 54045124 by 378
We want to figure out the number of times 54045124 can be divided by 378.

Going ahead to step 1:
When dividing 5 by 378, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 378

Step 2:
If we divide 54 by 378, we get 0 and a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Include the next digit (0) from the dividend after 54, then repeat: 540 / 378

Moving on to step 3:
If we divide 540 by 378, we get 1 and a remainder of 162.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 162 after subtracting 378 from 540.
Fetch the next digit (4) from the dividend, attach it to 162 and continue: 1624 / 378

Going ahead to step 4:
The number 378 fits into 1624 4 times, leaving a remainder of 112.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 1512 from 1624 to get 112.
Fetch the next digit (5) from the dividend, attach it to 112 and continue: 1125 / 378

Step 5:
When dividing 1125 by 378, we get 2 with a remainder of 369.
Write down 2 as next digit of the result. 
Result so far: 142.0
If we subtract 756 from 1125, we get 369.
Take the next digit (1) from the dividend and append it to 369, then repeat: 3691 / 378

Moving on to step 6:
378 goes into 3691 9 times with a remainder of 289.
The next digit of our result is 9. 
Result so far: 1429.0
If we take 3402 away from 3691, we end up with 289.
Grab the next digit (2) from the dividend, add it to 289, then carry on: 2892 / 378

Advancing to step 7:
378 goes into 2892 7 times with a remainder of 246.
The number 7 becomes the next digit in our result. 
Result so far: 14297.0
If we subtract 2646 from 2892, we get 246.
Take the next digit (4) from the dividend and append it to 246, then repeat: 2464 / 378

On to step 8:
378 can be fit into 2464 6 times, resulting in a remainder of 196.
The next digit of our result is 6. 
Result so far: 142976.0
If we subtract 2268 from 2464, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 9:
When dividing 1960 by 378, we get 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 142976.5
If we take 1890 away from 1960, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
The number 378 fits into 700 1 times, leaving a remainder of 322.
Record the quotient 1 as the next digit in the result. 
Result so far: 142976.51
If we subtract 378 from 700, we get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 11:
If we divide 3220 by 378, we get 8 and a remainder of 196.
Put 8 as the next digit of the answer. 
Result so far: 142976.518
Subtract 3024 from 3220 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 12:
When dividing 1960 by 378, we get 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 142976.5185
Subtract 1890 from 1960 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 13:
700 divided by 378 is 1 with a remainder of 322.
Put 1 as the next digit of the answer. 
Result so far: 142976.51851
Subtract 378 from 700 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Let's proceed to step 14:
The number 378 fits into 3220 8 times, leaving a remainder of 196.
Record the quotient 8 as the next digit in the result. 
Result so far: 142976.518518
If we take 3024 away from 3220, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 15:
1960 divided by 378 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 142976.5185185
The remainder is 70 after subtracting 1890 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 16:
If we divide 700 by 378, we get 1 and a remainder of 322.
The next digit of our result is 1. 
Result so far: 142976.51851851
Subtracting 378 from 700 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

The final outcome is 142976.51851851, with a leftover of 3.22e-07.
