641786 ÷ 78 
We're looking to find how many times 78 goes into 641786.

Advancing to step 1:
78 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 78

Step 2:
64 divided by 78 is 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Bring next digit (1) of the dividend behind the 64 and repeat the process: 641 / 78

Advancing to step 3:
78 can be fit into 641 8 times, resulting in a remainder of 17.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 624 from 641 to get 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 78

Let's proceed to step 4:
78 can be fit into 177 2 times, resulting in a remainder of 21.
The next digit of our result is 2. 
Result so far: 82.0
Subtracting 156 from 177 leaves us with 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 78

Step 5:
78 can be fit into 218 2 times, resulting in a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 822.0
The remainder is 62 after subtracting 156 from 218.
Append the next digit (6) from the dividend to 62 and continue with: 626 / 78

Going ahead to step 6:
78 goes into 626 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 8228.0
If we subtract 624 from 626, we get 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 7:
If we divide 20 by 78, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 8228.0
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.

Going ahead to step 8:
When dividing 200 by 78, we get 2 with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 8228.02
If we subtract 156 from 200, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
The number 78 fits into 440 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 8228.025
The remainder is 50 after subtracting 390 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
If we divide 500 by 78, we get 6 and a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 8228.0256
Deduct 468 from 500 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
If we divide 320 by 78, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 8228.02564
Subtracting 312 from 320 leaves us 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.

Advancing to step 12:
78 goes into 80 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 8228.025641
Deduct 78 from 80 and we're left 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 13:
78 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 8228.025641
Subtract 0 from 20 to get 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 14:
200 divided by 78 is 2 with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 8228.02564102
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.

The quotient of the division is 8228.02564102, and the remainder is 4.4e-08.
