641207 divided by 78 
We want to divide 641207 by 78.

Moving on to step 1:
6 divided by 78 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 78

Going ahead to step 2:
78 goes into 64 0 times with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Append the next digit (1) from the dividend to 64 and continue with: 641 / 78

Advancing to step 3:
When dividing 641 by 78, we get 8 with a remainder of 17.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 624 from 641, we get 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 78

Going ahead to step 4:
If we divide 172 by 78, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 82.0
The remainder is 16 after subtracting 156 from 172.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 78

Let's proceed to step 5:
78 goes into 160 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 822.0
Deduct 156 from 160 and we're left with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 78

Moving on to step 6:
47 divided by 78 is 0 with a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 8220.0
If we subtract 0 from 47, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 7:
The number 78 fits into 470 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 8220.6
If we take 468 away from 470, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
78 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 8220.6
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
78 can be fit into 200 2 times, resulting in a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 8220.602
The remainder is 44 after subtracting 156 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
78 goes into 440 5 times with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 8220.6025
Deduct 390 from 440 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
If we divide 500 by 78, we get 6 and a remainder of 32.
The next digit of our result is 6. 
Result so far: 8220.60256
The remainder is 32 after subtracting 468 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
If we divide 320 by 78, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 8220.602564
Deduct 312 from 320 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
When dividing 80 by 78, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 8220.6025641
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
78 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 8220.6025641
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 8220.6025641, with a leftover of 2e-08.
