53948133 ÷ 378 
We want to figure out the number of times 53948133 can be divided by 378.

Moving on to step 1:
5 divided by 378 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 378

Moving on to step 2:
If we divide 53 by 378, we get 0 and a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Append the next digit (9) from the dividend to 53 and continue with: 539 / 378

Going ahead to step 3:
The number 378 fits into 539 1 times, leaving a remainder of 161.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 378 from 539 and we're left with 161.
Bring next digit (4) of the dividend behind the 161 and repeat the process: 1614 / 378

Let's proceed to step 4:
If we divide 1614 by 378, we get 4 and a remainder of 102.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 1512 from 1614 to get 102.
Append the next digit (8) from the dividend to 102 and continue with: 1028 / 378

Let's proceed to step 5:
378 can be fit into 1028 2 times, resulting in a remainder of 272.
The next digit of our result is 2. 
Result so far: 142.0
Subtracting 756 from 1028 leaves us with 272.
Append the next digit (1) from the dividend to 272 and continue with: 2721 / 378

Advancing to step 6:
When dividing 2721 by 378, we get 7 with a remainder of 75.
Write down 7 as next digit of the result. 
Result so far: 1427.0
Deduct 2646 from 2721 and we're left with 75.
Fetch the next digit (3) from the dividend, attach it to 75 and continue: 753 / 378

Going ahead to step 7:
If we divide 753 by 378, we get 1 and a remainder of 375.
Use 1 as the next digit of our solution. 
Result so far: 14271.0
The remainder is 375 after subtracting 378 from 753.
Append the next digit (3) from the dividend to 375 and continue with: 3753 / 378

On to step 8:
3753 divided by 378 is 9 with a remainder of 351.
The number 9 becomes the next digit in our result. 
Result so far: 142719.0
Deduct 3402 from 3753 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

On to step 9:
The number 378 fits into 3510 9 times, leaving a remainder of 108.
Write down 9 as next digit of the result. 
Result so far: 142719.9
Subtract 3402 from 3510 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 10:
When dividing 1080 by 378, we get 2 with a remainder of 324.
Use 2 as the next digit of our solution. 
Result so far: 142719.92
If we take 756 away from 1080, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 11:
The number 378 fits into 3240 8 times, leaving a remainder of 216.
Write down 8 as next digit of the result. 
Result so far: 142719.928
The remainder is 216 after subtracting 3024 from 3240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 12:
378 can be fit into 2160 5 times, resulting in a remainder of 270.
The next digit of our result is 5. 
Result so far: 142719.9285
Deduct 1890 from 2160 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 13:
When dividing 2700 by 378, we get 7 with a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 142719.92857
Deduct 2646 from 2700 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 14:
540 divided by 378 is 1 with a remainder of 162.
Record the quotient 1 as the next digit in the result. 
Result so far: 142719.928571
Subtract 378 from 540 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Let's proceed to step 15:
When dividing 1620 by 378, we get 4 with a remainder of 108.
Put 4 as the next digit of the answer. 
Result so far: 142719.9285714
Deduct 1512 from 1620 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 16:
1080 divided by 378 is 2 with a remainder of 324.
The number 2 becomes the next digit in our result. 
Result so far: 142719.92857142
Subtracting 756 from 1080 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

The final result is 142719.92857142 with a remainder of 3.24e-07.
