Let's divide 507907 by 78
We want to divide 507907 by 78.

Advancing to step 1:
If we divide 5 by 78, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 78

On to step 2:
78 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Include the next digit (7) from the dividend after 50, then repeat: 507 / 78

Step 3:
When dividing 507 by 78, we get 6 with a remainder of 39.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 468 from 507, we get 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 78

Advancing to step 4:
If we divide 399 by 78, we get 5 and a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 65.0
Deduct 390 from 399 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 78

Let's proceed to step 5:
The number 78 fits into 90 1 times, leaving a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 651.0
Subtracting 78 from 90 leaves us with 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 78

On to step 6:
The number 78 fits into 127 1 times, leaving a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 6511.0
The remainder is 49 after subtracting 78 from 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
78 can be fit into 490 6 times, resulting in a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 6511.6
The remainder is 22 after subtracting 468 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
If we divide 220 by 78, we get 2 and a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 6511.62
Subtracting 156 from 220 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
The number 78 fits into 640 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 6511.628
Subtract 624 from 640 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
78 goes into 160 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 6511.6282
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
78 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 6511.6282
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
78 goes into 400 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 6511.628205
Deduct 390 from 400 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
If we divide 100 by 78, we get 1 and a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 6511.6282051
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
78 can be fit into 220 2 times, resulting in a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 6511.62820512
Subtract 156 from 220 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 6511.62820512, with a leftover of 6.4e-08.
