We look at the division of 628434 by 78 
We're looking to find how many times 78 goes into 628434.

Advancing to step 1:
The number 78 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 78

Let's proceed to step 2:
62 divided by 78 is 0 with a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 62 leaves us with 62.
Take the next digit (8) from the dividend and append it to 62, then repeat: 628 / 78

Let's proceed to step 3:
When dividing 628 by 78, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 624 from 628, we get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 78

On to step 4:
78 goes into 44 0 times with a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Deduct 0 from 44 and we're left with 44.
Grab the next digit (3) from the dividend, add it to 44, then carry on: 443 / 78

Advancing to step 5:
The number 78 fits into 443 5 times, leaving a remainder of 53.
Record the quotient 5 as the next digit in the result. 
Result so far: 805.0
Deduct 390 from 443 and we're left with 53.
Grab the next digit (4) from the dividend, add it to 53, then carry on: 534 / 78

Let's proceed to step 6:
If we divide 534 by 78, we get 6 and a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 8056.0
If we take 468 away from 534, we end up 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.

Let's proceed to step 7:
78 can be fit into 660 8 times, resulting in a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 8056.8
Deduct 624 from 660 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
78 goes into 360 4 times with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 8056.84
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.

Let's proceed to step 9:
The number 78 fits into 480 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 8056.846
Subtract 468 from 480 to 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.

Step 10:
The number 78 fits into 120 1 times, leaving a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 8056.8461
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.

Let's proceed to step 11:
The number 78 fits into 420 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 8056.84615
The remainder is 30 after subtracting 390 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
300 divided by 78 is 3 with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 8056.846153
Subtract 234 from 300 to get 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 13:
The number 78 fits into 660 8 times, leaving a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 8056.8461538
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.

On to step 14:
If we divide 360 by 78, we get 4 and a remainder of 48.
The next digit of our result is 4. 
Result so far: 8056.84615384
Subtract 312 from 360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 8056.84615384, and the remainder is 4.8e-08.
