We divide 400423 by 78
Let's see how many times 78 fits into 400423.

Moving on to step 1:
The number 78 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 78

Let's proceed to step 2:
The number 78 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 78

Let's proceed to step 3:
78 can be fit into 400 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 390 from 400 leaves us with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 78

Going ahead to step 4:
The number 78 fits into 104 1 times, leaving a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 51.0
If we take 78 away from 104, we end up with 26.
Grab the next digit (2) from the dividend, add it to 26, then carry on: 262 / 78

On to step 5:
262 divided by 78 is 3 with a remainder of 28.
The next digit of our result is 3. 
Result so far: 513.0
If we subtract 234 from 262, we get 28.
Take the next digit (3) from the dividend and append it to 28, then repeat: 283 / 78

Step 6:
When dividing 283 by 78, we get 3 with a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 5133.0
Subtracting 234 from 283 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
When dividing 490 by 78, we get 6 with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 5133.6
If we take 468 away from 490, we end up 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.

Let's proceed to step 8:
220 divided by 78 is 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 5133.62
If we subtract 156 from 220, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
78 goes into 640 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 5133.628
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.

Going ahead to step 10:
160 divided by 78 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 5133.6282
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.

On to step 11:
The number 78 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 5133.6282
Deduct 0 from 40 and we're left with 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 12:
When dividing 400 by 78, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 5133.628205
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
The number 78 fits into 100 1 times, leaving a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 5133.6282051
If we take 78 away from 100, we end up 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.

Let's proceed to step 14:
The number 78 fits into 220 2 times, leaving a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 5133.62820512
The remainder is 64 after subtracting 156 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 5133.62820512, with a leftover of 6.4e-08.
