We divide 397473 by 78
We want to figure out the number of times 397473 can be divided by 78.

Let's proceed to step 1:
78 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 78

Let's proceed to step 2:
If we divide 39 by 78, we get 0 and a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Grab the next digit (7) from the dividend, add it to 39, then carry on: 397 / 78

Going ahead to step 3:
397 divided by 78 is 5 with a remainder of 7.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 390 from 397 leaves us with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 78

On to step 4:
The number 78 fits into 74 0 times, leaving a remainder of 74.
The next digit of our result is 0. 
Result so far: 50.0
The remainder is 74 after subtracting 0 from 74.
Bring next digit (7) of the dividend behind the 74 and repeat the process: 747 / 78

Step 5:
If we divide 747 by 78, we get 9 and a remainder of 45.
Use 9 as the next digit of our solution. 
Result so far: 509.0
If we subtract 702 from 747, we get 45.
Fetch the next digit (3) from the dividend, attach it to 45 and continue: 453 / 78

Step 6:
If we divide 453 by 78, we get 5 and a remainder of 63.
Put 5 as the next digit of the answer. 
Result so far: 5095.0
Subtracting 390 from 453 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 7:
When dividing 630 by 78, we get 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 5095.8
If we take 624 away from 630, we end up 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.

Let's proceed to step 8:
60 divided by 78 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 5095.8
Deduct 0 from 60 and we're left 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.

On to step 9:
If we divide 600 by 78, we get 7 and a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 5095.807
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.

On to step 10:
The number 78 fits into 540 6 times, leaving a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 5095.8076
The remainder is 72 after subtracting 468 from 540.
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 11:
720 divided by 78 is 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 5095.80769
If we take 702 away from 720, we end up 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.

On to step 12:
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: 5095.807692
If we subtract 156 from 180, we 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.

Let's proceed to step 13:
78 goes into 240 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 5095.8076923
Subtracting 234 from 240 leaves us 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.

Advancing to step 14:
78 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 5095.8076923
Deduct 0 from 60 and we're left 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.

In conclusion, the division gives 5095.8076923 with a balance of 6e-08.
