We're dividing 840188 by 78 
Our goal is to divide 840188 by 78.

Advancing to step 1:
When dividing 8 by 78, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 78

Going ahead to step 2:
84 divided by 78 is 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 6 after subtracting 78 from 84.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 78

Going ahead to step 3:
78 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 60, we end up with 60.
Bring next digit (1) of the dividend behind the 60 and repeat the process: 601 / 78

Step 4:
If we divide 601 by 78, we get 7 and a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
Deduct 546 from 601 and we're left with 55.
Grab the next digit (8) from the dividend, add it to 55, then carry on: 558 / 78

Step 5:
When dividing 558 by 78, we get 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 1077.0
Deduct 546 from 558 and we're left with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 78

Going ahead to step 6:
The number 78 fits into 128 1 times, leaving a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 10771.0
If we take 78 away from 128, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
The number 78 fits into 500 6 times, leaving a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 10771.6
If we take 468 away from 500, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 8:
320 divided by 78 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 10771.64
If we subtract 312 from 320, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
If we divide 80 by 78, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 10771.641
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
If we divide 20 by 78, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 10771.641
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
78 goes into 200 2 times with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 10771.64102
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 12:
When dividing 440 by 78, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 10771.641025
If we subtract 390 from 440, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
78 can be fit into 500 6 times, resulting in a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 10771.6410256
If we subtract 468 from 500, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
78 can be fit into 320 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 10771.64102564
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 10771.64102564 with a remainder of 8e-09.
