641412 ÷ 78 
We want to divide 641412 by 78.

Moving on to step 1:
If we divide 6 by 78, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 78

Moving on to step 2:
If we divide 64 by 78, we get 0 and a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Grab the next digit (1) from the dividend, add it to 64, then carry on: 641 / 78

Advancing to step 3:
78 can be fit into 641 8 times, resulting in a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 624 from 641 to get 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 78

Let's proceed to step 4:
174 divided by 78 is 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 82.0
Deduct 156 from 174 and we're left with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 78

On to step 5:
If we divide 181 by 78, we get 2 and a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 822.0
Subtract 156 from 181 to get 25.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 78

Advancing to step 6:
The number 78 fits into 252 3 times, leaving a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 8223.0
If we take 234 away from 252, 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.

On to step 7:
When dividing 180 by 78, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 8223.2
If we subtract 156 from 180, we 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.

Advancing to step 8:
If we divide 240 by 78, we get 3 and a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 8223.23
If we take 234 away from 240, we end up 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.

Step 9:
The number 78 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 8223.23
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
78 can be fit into 600 7 times, resulting in a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 8223.2307
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.

Step 11:
If we divide 540 by 78, we get 6 and a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 8223.23076
Deduct 468 from 540 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 12:
78 goes into 720 9 times with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 8223.230769
Subtract 702 from 720 to 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.

Going ahead to step 13:
78 goes into 180 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 8223.2307692
If we take 156 away from 180, we end up 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 14:
240 divided by 78 is 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 8223.23076923
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.

In conclusion, the division gives 8223.23076923 with a balance of 6e-09.
