Let's divide 159338 by 78
We're looking to find how many times 78 goes into 159338.

Let's proceed to step 1:
If we divide 1 by 78, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 78

Moving on to step 2:
When dividing 15 by 78, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 78

On to step 3:
The number 78 fits into 159 2 times, leaving a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 156 from 159 to get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 78

Let's proceed to step 4:
78 can be fit into 33 0 times, resulting in a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtract 0 from 33 to get 33.
Take the next digit (3) from the dividend and append it to 33, then repeat: 333 / 78

On to step 5:
If we divide 333 by 78, we get 4 and a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 204.0
If we take 312 away from 333, we end up with 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 78

Going ahead to step 6:
218 divided by 78 is 2 with a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 2042.0
If we take 156 away from 218, 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.

Advancing to step 7:
78 goes into 620 7 times with a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 2042.7
If we subtract 546 from 620, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 8:
78 can be fit into 740 9 times, resulting in a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 2042.79
If we subtract 702 from 740, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
If we divide 380 by 78, we get 4 and a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 2042.794
If we subtract 312 from 380, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 10:
If we divide 680 by 78, we get 8 and a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 2042.7948
The remainder is 56 after subtracting 624 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
If we divide 560 by 78, we get 7 and a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 2042.79487
Subtracting 546 from 560 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 12:
78 can be fit into 140 1 times, resulting in a remainder of 62.
The next digit of our result is 1. 
Result so far: 2042.794871
Subtract 78 from 140 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 13:
If we divide 620 by 78, we get 7 and a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 2042.7948717
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 14:
The number 78 fits into 740 9 times, leaving a remainder of 38.
The next digit of our result is 9. 
Result so far: 2042.79487179
Subtracting 702 from 740 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 2042.79487179, with a leftover of 3.8e-08.
