Let's divide 651857 by 78
We're looking to find how many times 78 goes into 651857.

Advancing to step 1:
78 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 78

Advancing to step 2:
If we divide 65 by 78, we get 0 and a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Include the next digit (1) from the dividend after 65, then repeat: 651 / 78

Going ahead to step 3:
When dividing 651 by 78, we get 8 with a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 624 from 651, we get 27.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 78

Moving on to step 4:
78 can be fit into 278 3 times, resulting in a remainder of 44.
The next digit of our result is 3. 
Result so far: 83.0
Subtract 234 from 278 to get 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 78

Going ahead to step 5:
445 divided by 78 is 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 835.0
Deduct 390 from 445 and we're left with 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 78

Advancing to step 6:
The number 78 fits into 557 7 times, leaving a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 8357.0
If we take 546 away from 557, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
When dividing 110 by 78, we get 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 8357.1
The remainder is 32 after subtracting 78 from 110.
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 8:
78 goes into 320 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 8357.14
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.

On to step 9:
If we divide 80 by 78, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 8357.141
If we subtract 78 from 80, 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.

Moving on to step 10:
The number 78 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 8357.141
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
If we divide 200 by 78, we get 2 and a remainder of 44.
The next digit of our result is 2. 
Result so far: 8357.14102
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.

Advancing to step 12:
When dividing 440 by 78, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 8357.141025
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 13:
78 goes into 500 6 times with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 8357.1410256
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 14:
78 goes into 320 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 8357.14102564
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 8357.14102564 and a remainder of 8e-09.
