We're dividing 154341 by 78 
Our goal is to divide 154341 by 78.

Going ahead to step 1:
When dividing 1 by 78, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 78

Advancing to step 2:
The number 78 fits into 15 0 times, leaving a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 78

Moving on to step 3:
If we divide 154 by 78, we get 1 and a remainder of 76.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 78 from 154 to get 76.
Take the next digit (3) from the dividend and append it to 76, then repeat: 763 / 78

Going ahead to step 4:
78 goes into 763 9 times with a remainder of 61.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 702 from 763 to get 61.
Append the next digit (4) from the dividend to 61 and continue with: 614 / 78

On to step 5:
The number 78 fits into 614 7 times, leaving a remainder of 68.
Record the quotient 7 as the next digit in the result. 
Result so far: 197.0
The remainder is 68 after subtracting 546 from 614.
Bring next digit (1) of the dividend behind the 68 and repeat the process: 681 / 78

Going ahead to step 6:
681 divided by 78 is 8 with a remainder of 57.
Record the quotient 8 as the next digit in the result. 
Result so far: 1978.0
Subtract 624 from 681 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 7:
78 can be fit into 570 7 times, resulting in a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 1978.7
Subtracting 546 from 570 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
240 divided by 78 is 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 1978.73
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
60 divided by 78 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 1978.73
Subtracting 0 from 60 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.

Advancing to step 10:
78 can be fit into 600 7 times, resulting in a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 1978.7307
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.

Going ahead to step 11:
78 can be fit into 540 6 times, resulting in a remainder of 72.
The next digit of our result is 6. 
Result so far: 1978.73076
Subtracting 468 from 540 leaves us 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.

Let's proceed to step 12:
When dividing 720 by 78, we get 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 1978.730769
Deduct 702 from 720 and we're left 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 13:
78 goes into 180 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 1978.7307692
If we take 156 away from 180, we end up with 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 14:
When dividing 240 by 78, we get 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 1978.73076923
Deduct 234 from 240 and we're left 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.

After the division, we end up with 1978.73076923 and a remainder of 6e-09.
