Let's divide 53378 by 39
We want to divide 53378 by 39.

Step 1:
If we divide 5 by 39, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 39

Moving on to step 2:
39 goes into 53 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 14 after subtracting 39 from 53.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 39

Going ahead to step 3:
When dividing 143 by 39, we get 3 with a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 117 from 143 leaves us with 26.
Append the next digit (7) from the dividend to 26 and continue with: 267 / 39

Going ahead to step 4:
If we divide 267 by 39, we get 6 and a remainder of 33.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
If we take 234 away from 267, we end up with 33.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 39

On to step 5:
338 divided by 39 is 8 with a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 1368.0
Subtract 312 from 338 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 6:
The number 39 fits into 260 6 times, leaving a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 1368.6
Subtract 234 from 260 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 7:
If we divide 260 by 39, we get 6 and a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 1368.66
If we subtract 234 from 260, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 1368.66, with a leftover of 0.026.
