Let's divide 558231 by 78
Let's see how many times 78 fits into 558231.

Step 1:
When dividing 5 by 78, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 78

Advancing to step 2:
78 goes into 55 0 times with a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Take the next digit (8) from the dividend and append it to 55, then repeat: 558 / 78

Going ahead to step 3:
78 can be fit into 558 7 times, resulting in a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 546 from 558 and we're left with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 78

Let's proceed to step 4:
78 goes into 122 1 times with a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 71.0
The remainder is 44 after subtracting 78 from 122.
Bring next digit (3) of the dividend behind the 44 and repeat the process: 443 / 78

Moving on to step 5:
78 can be fit into 443 5 times, resulting in a remainder of 53.
The number 5 becomes the next digit in our result. 
Result so far: 715.0
If we subtract 390 from 443, we get 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 78

Let's proceed to step 6:
531 divided by 78 is 6 with a remainder of 63.
Put 6 as the next digit of the answer. 
Result so far: 7156.0
The remainder is 63 after subtracting 468 from 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 7:
78 goes into 630 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 7156.8
Subtract 624 from 630 to get 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 8:
60 divided by 78 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 7156.8
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
78 can be fit into 600 7 times, resulting in a remainder of 54.
The next digit of our result is 7. 
Result so far: 7156.807
The remainder is 54 after subtracting 546 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 10:
78 goes into 540 6 times with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 7156.8076
Subtract 468 from 540 to get 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 11:
The number 78 fits into 720 9 times, leaving a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 7156.80769
If we subtract 702 from 720, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
180 divided by 78 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 7156.807692
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.

On to step 13:
78 goes into 240 3 times with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 7156.8076923
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 14:
If we divide 60 by 78, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 7156.8076923
Subtracting 0 from 60 leaves us 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.

Our division results in 7156.8076923 with a remaining 6e-08.
