Let's divide 636354 by 78
Our goal is to divide 636354 by 78.

Let's proceed to step 1:
If we divide 6 by 78, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 78

Let's proceed to step 2:
When dividing 63 by 78, we get 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Take the next digit (6) from the dividend and append it to 63, then repeat: 636 / 78

Going ahead to step 3:
636 divided by 78 is 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 624 from 636, we get 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 78

Moving on to step 4:
The number 78 fits into 123 1 times, leaving a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Subtracting 78 from 123 leaves us with 45.
Take the next digit (5) from the dividend and append it to 45, then repeat: 455 / 78

On to step 5:
When dividing 455 by 78, we get 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 815.0
If we take 390 away from 455, we end up with 65.
Take the next digit (4) from the dividend and append it to 65, then repeat: 654 / 78

On to step 6:
78 goes into 654 8 times with a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 8158.0
The remainder is 30 after subtracting 624 from 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
78 goes into 300 3 times with a remainder of 66.
The next digit of our result is 3. 
Result so far: 8158.3
Subtracting 234 from 300 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 8:
When dividing 660 by 78, we get 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 8158.38
If we subtract 624 from 660, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
360 divided by 78 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 8158.384
Subtracting 312 from 360 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
When dividing 480 by 78, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 8158.3846
If we subtract 468 from 480, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
78 goes into 120 1 times with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 8158.38461
Subtract 78 from 120 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 12:
78 goes into 420 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 8158.384615
Subtracting 390 from 420 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
300 divided by 78 is 3 with a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 8158.3846153
Subtracting 234 from 300 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 14:
660 divided by 78 is 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 8158.38461538
The remainder is 36 after subtracting 624 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 8158.38461538 with a remaining 3.6e-08.
