161427 ÷ 78 
We want to divide 161427 by 78.

Step 1:
If we divide 1 by 78, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 78

Advancing to step 2:
The number 78 fits into 16 0 times, leaving a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 78

Let's proceed to step 3:
78 goes into 161 2 times with a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 5 after subtracting 156 from 161.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 78

Step 4:
When dividing 54 by 78, we get 0 with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 54 leaves us with 54.
Include the next digit (2) from the dividend after 54, then repeat: 542 / 78

Moving on to step 5:
542 divided by 78 is 6 with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 206.0
If we take 468 away from 542, we end up with 74.
Grab the next digit (7) from the dividend, add it to 74, then carry on: 747 / 78

Going ahead to step 6:
When dividing 747 by 78, we get 9 with a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 2069.0
Deduct 702 from 747 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 7:
When dividing 450 by 78, we get 5 with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 2069.5
Subtracting 390 from 450 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
When dividing 600 by 78, we get 7 with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 2069.57
If we take 546 away from 600, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 9:
78 goes into 540 6 times with a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 2069.576
Deduct 468 from 540 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 2069.5769
If we take 702 away from 720, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 11:
The number 78 fits into 180 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 2069.57692
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
When dividing 240 by 78, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 2069.576923
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
60 divided by 78 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 2069.576923
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
600 divided by 78 is 7 with a remainder of 54.
The next digit of our result is 7. 
Result so far: 2069.57692307
Deduct 546 from 600 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 2069.57692307, and the remainder is 5.4e-08.
