340393 divided by 78 
We're looking to find how many times 78 goes into 340393.

Let's proceed to step 1:
When dividing 3 by 78, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 78

Let's proceed to step 2:
78 goes into 34 0 times with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Append the next digit (0) from the dividend to 34 and continue with: 340 / 78

On to step 3:
If we divide 340 by 78, we get 4 and a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 312 from 340, we get 28.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 78

Going ahead to step 4:
If we divide 283 by 78, we get 3 and a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 43.0
If we take 234 away from 283, we end up with 49.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 78

Going ahead to step 5:
When dividing 499 by 78, we get 6 with a remainder of 31.
Write down 6 as next digit of the result. 
Result so far: 436.0
If we take 468 away from 499, we end up with 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 78

Going ahead to step 6:
78 can be fit into 313 4 times, resulting in a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4364.0
Subtract 312 from 313 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
78 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 4364.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
If we divide 100 by 78, we get 1 and a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 4364.01
Deduct 78 from 100 and we're left 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.

Step 9:
78 can be fit into 220 2 times, resulting in a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 4364.012
Subtracting 156 from 220 leaves us 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.

On to step 10:
If we divide 640 by 78, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 4364.0128
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
If we divide 160 by 78, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 4364.01282
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:
When dividing 40 by 78, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 4364.01282
Subtract 0 from 40 to 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.

Going ahead to step 13:
When dividing 400 by 78, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 4364.0128205
Subtracting 390 from 400 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on 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: 4364.01282051
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.

The final result is 4364.01282051 with a remainder of 2.2e-08.
