We're dividing 169257 by 78 
Our goal is to divide 169257 by 78.

Advancing to step 1:
When dividing 1 by 78, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 78

Advancing to step 2:
78 can be fit into 16 0 times, resulting in a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 78

Moving on to step 3:
78 goes into 169 2 times with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 156 away from 169, we end up with 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 78

Advancing to step 4:
78 can be fit into 132 1 times, resulting in a remainder of 54.
The next digit of our result is 1. 
Result so far: 21.0
Deduct 78 from 132 and we're left with 54.
Bring next digit (5) of the dividend behind the 54 and repeat the process: 545 / 78

Let's proceed to step 5:
The number 78 fits into 545 6 times, leaving a remainder of 77.
The next digit of our result is 6. 
Result so far: 216.0
Deduct 468 from 545 and we're left with 77.
Include the next digit (7) from the dividend after 77, then repeat: 777 / 78

On to step 6:
777 divided by 78 is 9 with a remainder of 75.
The next digit of our result is 9. 
Result so far: 2169.0
Subtracting 702 from 777 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 7:
When dividing 750 by 78, we get 9 with a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 2169.9
If we take 702 away from 750, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 8:
480 divided by 78 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 2169.96
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 9:
The number 78 fits into 120 1 times, leaving a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 2169.961
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.

On to step 10:
420 divided by 78 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 2169.9615
The remainder is 30 after subtracting 390 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
78 goes into 300 3 times with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 2169.96153
The remainder is 66 after subtracting 234 from 300.
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 12:
When dividing 660 by 78, we get 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 2169.961538
Deduct 624 from 660 and we're left 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.

Going ahead to step 13:
78 goes into 360 4 times with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 2169.9615384
Deduct 312 from 360 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
The number 78 fits into 480 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 2169.96153846
Subtract 468 from 480 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 2169.96153846 with a balance of 1.2e-08.
