169542 divided by 78 
Our goal is to divide 169542 by 78.

Advancing to step 1:
The number 78 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 78

Going ahead to step 2:
78 goes into 16 0 times with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 78

Moving on to step 3:
When dividing 169 by 78, we get 2 with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 156 from 169 and we're left with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 78

Step 4:
The number 78 fits into 135 1 times, leaving a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 57 after subtracting 78 from 135.
Take the next digit (4) from the dividend and append it to 57, then repeat: 574 / 78

Let's proceed to step 5:
If we divide 574 by 78, we get 7 and a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 217.0
Deduct 546 from 574 and we're left with 28.
Include the next digit (2) from the dividend after 28, then repeat: 282 / 78

Advancing to step 6:
If we divide 282 by 78, we get 3 and a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 2173.0
If we subtract 234 from 282, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 7:
If we divide 480 by 78, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 2173.6
The remainder is 12 after subtracting 468 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
78 goes into 120 1 times with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 2173.61
The remainder is 42 after subtracting 78 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
78 goes into 420 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 2173.615
Subtract 390 from 420 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
78 goes into 300 3 times with a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 2173.6153
Subtract 234 from 300 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 11:
660 divided by 78 is 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 2173.61538
Subtracting 624 from 660 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 12:
If we divide 360 by 78, we get 4 and a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 2173.615384
If we subtract 312 from 360, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
78 can be fit into 480 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 2173.6153846
Deduct 468 from 480 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
78 can be fit into 120 1 times, resulting in a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 2173.61538461
Deduct 78 from 120 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 2173.61538461 with a remainder of 4.2e-08.
