537843 ÷ 78 
Let's see how many times 78 fits into 537843.

On to step 1:
The number 78 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 78

Advancing to step 2:
If we divide 53 by 78, we get 0 and a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Include the next digit (7) from the dividend after 53, then repeat: 537 / 78

Advancing to step 3:
When dividing 537 by 78, we get 6 with a remainder of 69.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 468 from 537 to get 69.
Fetch the next digit (8) from the dividend, attach it to 69 and continue: 698 / 78

Let's proceed to step 4:
If we divide 698 by 78, we get 8 and a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 68.0
Subtracting 624 from 698 leaves us with 74.
Bring next digit (4) of the dividend behind the 74 and repeat the process: 744 / 78

Let's proceed to step 5:
When dividing 744 by 78, we get 9 with a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 689.0
If we take 702 away from 744, we end up with 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 78

Going ahead to step 6:
The number 78 fits into 423 5 times, leaving a remainder of 33.
Put 5 as the next digit of the answer. 
Result so far: 6895.0
Subtract 390 from 423 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 7:
When dividing 330 by 78, we get 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 6895.4
If we subtract 312 from 330, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
180 divided by 78 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 6895.42
The remainder is 24 after subtracting 156 from 180.
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 9:
If we divide 240 by 78, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 6895.423
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 10:
If we divide 60 by 78, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 6895.423
The remainder is 60 after subtracting 0 from 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 11:
The number 78 fits into 600 7 times, leaving a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 6895.42307
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.

Moving on to step 12:
78 can be fit into 540 6 times, resulting in a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 6895.423076
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.

On to step 13:
78 goes into 720 9 times with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 6895.4230769
If we subtract 702 from 720, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
78 can be fit into 180 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 6895.42307692
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.

After the division, we end up with 6895.42307692 and a remainder of 2.4e-08.
