We look at the division of 642627 by 78 
We want to divide 642627 by 78.

Advancing to step 1:
78 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 78

Step 2:
78 goes into 64 0 times with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Bring next digit (2) of the dividend behind the 64 and repeat the process: 642 / 78

Step 3:
The number 78 fits into 642 8 times, leaving a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 624 from 642 leaves us with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 78

Advancing to step 4:
186 divided by 78 is 2 with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
Subtracting 156 from 186 leaves us with 30.
Append the next digit (2) from the dividend to 30 and continue with: 302 / 78

Advancing to step 5:
The number 78 fits into 302 3 times, leaving a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 823.0
Subtract 234 from 302 to get 68.
Take the next digit (7) from the dividend and append it to 68, then repeat: 687 / 78

Step 6:
78 goes into 687 8 times with a remainder of 63.
The number 8 becomes the next digit in our result. 
Result so far: 8238.0
If we subtract 624 from 687, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 7:
78 can be fit into 630 8 times, resulting in a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 8238.8
Deduct 624 from 630 and we're left with 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:
78 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 8238.8
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.

On to step 9:
The number 78 fits into 600 7 times, leaving a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 8238.807
If we subtract 546 from 600, we get 54.
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:
The number 78 fits into 540 6 times, leaving a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 8238.8076
If we subtract 468 from 540, we 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.

Step 11:
When dividing 720 by 78, we get 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 8238.80769
If we take 702 away from 720, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead 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: 8238.807692
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
When dividing 240 by 78, we get 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 8238.8076923
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.

Moving on to step 14:
If we divide 60 by 78, we get 0 and a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 8238.8076923
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.

In conclusion, the division gives 8238.8076923 with a balance of 6e-08.
