426431 divided by 78 
Let's see how many times 78 fits into 426431.

Moving on to step 1:
When dividing 4 by 78, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 78

Advancing to step 2:
When dividing 42 by 78, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 78

Going ahead to step 3:
If we divide 426 by 78, we get 5 and a remainder of 36.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 390 from 426 leaves us with 36.
Fetch the next digit (4) from the dividend, attach it to 36 and continue: 364 / 78

Let's proceed to step 4:
The number 78 fits into 364 4 times, leaving a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 54.0
Deduct 312 from 364 and we're left with 52.
Take the next digit (3) from the dividend and append it to 52, then repeat: 523 / 78

On to step 5:
The number 78 fits into 523 6 times, leaving a remainder of 55.
Write down 6 as next digit of the result. 
Result so far: 546.0
The remainder is 55 after subtracting 468 from 523.
Take the next digit (1) from the dividend and append it to 55, then repeat: 551 / 78

Step 6:
If we divide 551 by 78, we get 7 and a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 5467.0
Subtract 546 from 551 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
78 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 5467.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
78 goes into 500 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 5467.06
If we subtract 468 from 500, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
The number 78 fits into 320 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 5467.064
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
When dividing 80 by 78, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 5467.0641
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
20 divided by 78 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 5467.0641
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
78 can be fit into 200 2 times, resulting in a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 5467.064102
The remainder is 44 after subtracting 156 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
78 goes into 440 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 5467.0641025
If we subtract 390 from 440, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
500 divided by 78 is 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 5467.06410256
Deduct 468 from 500 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 5467.06410256, with a leftover of 3.2e-08.
