We're dividing 491643 by 78 
Our goal is to divide 491643 by 78.

Going ahead to step 1:
When dividing 4 by 78, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 78

Let's proceed to step 2:
The number 78 fits into 49 0 times, leaving a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Grab the next digit (1) from the dividend, add it to 49, then carry on: 491 / 78

Advancing to step 3:
78 goes into 491 6 times with a remainder of 23.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 468 from 491 and we're left with 23.
Take the next digit (6) from the dividend and append it to 23, then repeat: 236 / 78

Advancing to step 4:
If we divide 236 by 78, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 63.0
Deduct 234 from 236 and we're left with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 78

Going ahead to step 5:
78 can be fit into 24 0 times, resulting in a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 630.0
If we take 0 away from 24, we end up with 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 78

Let's proceed to step 6:
78 can be fit into 243 3 times, resulting in a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 6303.0
Subtract 234 from 243 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
When dividing 90 by 78, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 6303.1
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
When dividing 120 by 78, we get 1 with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 6303.11
If we take 78 away from 120, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 6303.11 with a balance of 0.042.
