400276 divided by 78 
Let's see how many times 78 fits into 400276.

Advancing to step 1:
When dividing 4 by 78, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 78

Advancing to step 2:
78 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 78

Advancing to step 3:
If we divide 400 by 78, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 390 from 400, we get 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 78

Step 4:
78 goes into 102 1 times with a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 51.0
Subtract 78 from 102 to get 24.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 78

On to step 5:
If we divide 247 by 78, we get 3 and a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 513.0
Subtract 234 from 247 to get 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 78

Step 6:
136 divided by 78 is 1 with a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 5131.0
Subtract 78 from 136 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 7:
The number 78 fits into 580 7 times, leaving a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 5131.7
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
78 can be fit into 340 4 times, resulting in a remainder of 28.
The next digit of our result is 4. 
Result so far: 5131.74
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
78 can be fit into 280 3 times, resulting in a remainder of 46.
The next digit of our result is 3. 
Result so far: 5131.743
The remainder is 46 after subtracting 234 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 10:
The number 78 fits into 460 5 times, leaving a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 5131.7435
Subtracting 390 from 460 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
When dividing 700 by 78, we get 8 with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 5131.74358
If we take 624 away from 700, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 12:
When dividing 760 by 78, we get 9 with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 5131.743589
Deduct 702 from 760 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 13:
78 can be fit into 580 7 times, resulting in a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 5131.7435897
Deduct 546 from 580 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 14:
The number 78 fits into 340 4 times, leaving a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 5131.74358974
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 5131.74358974, with a leftover of 2.8e-08.
