We look at the division of 843376 by 78 
Let's see how many times 78 fits into 843376.

Going ahead to step 1:
78 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 78

On to step 2:
78 goes into 84 1 times with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 6 after subtracting 78 from 84.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 78

Advancing to step 3:
The number 78 fits into 63 0 times, leaving a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 63 and we're left with 63.
Bring next digit (3) of the dividend behind the 63 and repeat the process: 633 / 78

Going ahead to step 4:
When dividing 633 by 78, we get 8 with a remainder of 9.
The next digit of our result is 8. 
Result so far: 108.0
Subtracting 624 from 633 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 78

Moving on to step 5:
78 can be fit into 97 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1081.0
Deduct 78 from 97 and we're left with 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 78

Moving on to step 6:
196 divided by 78 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 10812.0
If we subtract 156 from 196, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
If we divide 400 by 78, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 10812.5
Subtract 390 from 400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
78 can be fit into 100 1 times, resulting in a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 10812.51
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
The number 78 fits into 220 2 times, leaving a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 10812.512
Deduct 156 from 220 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 10:
If we divide 640 by 78, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 10812.5128
The remainder is 16 after subtracting 624 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
78 can be fit into 160 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 10812.51282
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
40 divided by 78 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 10812.51282
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
400 divided by 78 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 10812.5128205
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
When dividing 100 by 78, we get 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 10812.51282051
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 10812.51282051, with a leftover of 2.2e-08.
