Let's divide 669701 by 78
We're looking to find how many times 78 goes into 669701.

Going ahead to step 1:
If we divide 6 by 78, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 78

Step 2:
The number 78 fits into 66 0 times, leaving a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 78

Step 3:
The number 78 fits into 669 8 times, leaving a remainder of 45.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 624 from 669, we get 45.
Grab the next digit (7) from the dividend, add it to 45, then carry on: 457 / 78

Let's proceed to step 4:
457 divided by 78 is 5 with a remainder of 67.
Write down 5 as next digit of the result. 
Result so far: 85.0
Subtract 390 from 457 to get 67.
Fetch the next digit (0) from the dividend, attach it to 67 and continue: 670 / 78

On to step 5:
670 divided by 78 is 8 with a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 858.0
If we subtract 624 from 670, we get 46.
Append the next digit (1) from the dividend to 46 and continue with: 461 / 78

On to step 6:
78 can be fit into 461 5 times, resulting in a remainder of 71.
The next digit of our result is 5. 
Result so far: 8585.0
If we subtract 390 from 461, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 7:
78 can be fit into 710 9 times, resulting in a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 8585.9
Subtracting 702 from 710 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 8:
The number 78 fits into 80 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 8585.91
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 9:
The number 78 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 8585.91
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.

Moving on to step 10:
78 goes into 200 2 times with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 8585.9102
Subtracting 156 from 200 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
440 divided by 78 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 8585.91025
Subtracting 390 from 440 leaves us 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 12:
The number 78 fits into 500 6 times, leaving a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 8585.910256
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.

On to step 13:
The number 78 fits into 320 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 8585.9102564
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 14:
80 divided by 78 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 8585.91025641
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.

After the division, we end up with 8585.91025641 and a remainder of 2e-09.
