We're dividing 165435 by 78 
Our goal is to divide 165435 by 78.

On to step 1:
1 divided by 78 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 78

Step 2:
The number 78 fits into 16 0 times, leaving a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 78

Moving on to step 3:
165 divided by 78 is 2 with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 156 from 165, we get 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 78

Step 4:
94 divided by 78 is 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 16 after subtracting 78 from 94.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 78

On to step 5:
If we divide 163 by 78, we get 2 and a remainder of 7.
The next digit of our result is 2. 
Result so far: 212.0
If we take 156 away from 163, we end up with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 78

Going ahead to step 6:
78 goes into 75 0 times with a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 2120.0
If we take 0 away from 75, we end up 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.
Put 9 as the next digit of the answer. 
Result so far: 2120.9
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.

Step 8:
78 can be fit into 480 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 2120.96
Subtracting 468 from 480 leaves us 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.

Step 9:
120 divided by 78 is 1 with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 2120.961
Subtract 78 from 120 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
If we divide 420 by 78, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 2120.9615
Subtracting 390 from 420 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
The number 78 fits into 300 3 times, leaving a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 2120.96153
If we take 234 away from 300, we end up with 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 12:
660 divided by 78 is 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 2120.961538
If we take 624 away from 660, we end up 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:
When dividing 360 by 78, we get 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 2120.9615384
Subtract 312 from 360 to 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.

Moving on to step 14:
The number 78 fits into 480 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 2120.96153846
If we subtract 468 from 480, we 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 2120.96153846 with a balance of 1.2e-08.
