401394 ÷ 78 
We're looking to find how many times 78 goes into 401394.

On to step 1:
78 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 78

Advancing to step 2:
The number 78 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 78

Let's proceed to step 3:
78 can be fit into 401 5 times, resulting in a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 390 from 401, we get 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 78

Moving on to step 4:
78 goes into 113 1 times with a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we take 78 away from 113, we end up with 35.
Take the next digit (9) from the dividend and append it to 35, then repeat: 359 / 78

Moving on to step 5:
78 can be fit into 359 4 times, resulting in a remainder of 47.
The next digit of our result is 4. 
Result so far: 514.0
Subtracting 312 from 359 leaves us with 47.
Include the next digit (4) from the dividend after 47, then repeat: 474 / 78

Going ahead to step 6:
If we divide 474 by 78, we get 6 and a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 5146.0
If we take 468 away from 474, 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.

Advancing to step 7:
78 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 5146.0
If we take 0 away from 60, we end up 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.

Let's proceed to step 8:
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: 5146.07
Subtracting 546 from 600 leaves us 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 9:
If we divide 540 by 78, we get 6 and a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 5146.076
Deduct 468 from 540 and we're left 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.

Moving on to step 10:
If we divide 720 by 78, we get 9 and a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 5146.0769
Deduct 702 from 720 and we're left 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.

Advancing to step 11:
180 divided by 78 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 5146.07692
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
When dividing 240 by 78, we get 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 5146.076923
The remainder is 6 after subtracting 234 from 240.
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 13:
When dividing 60 by 78, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 5146.076923
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.

Going ahead to step 14:
The number 78 fits into 600 7 times, leaving a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 5146.07692307
Subtracting 546 from 600 leaves us 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.

In conclusion, the division gives 5146.07692307 with a balance of 5.4e-08.
