We look at the division of 778671 by 39 
We're looking to find how many times 39 goes into 778671.

Step 1:
7 divided by 39 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 39

Going ahead to step 2:
If we divide 77 by 39, we get 1 and a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 39 away from 77, we end up with 38.
Grab the next digit (8) from the dividend, add it to 38, then carry on: 388 / 39

Advancing to step 3:
When dividing 388 by 39, we get 9 with a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 351 from 388 to get 37.
Fetch the next digit (6) from the dividend, attach it to 37 and continue: 376 / 39

Let's proceed to step 4:
376 divided by 39 is 9 with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 199.0
Deduct 351 from 376 and we're left with 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 39

On to step 5:
The number 39 fits into 257 6 times, leaving a remainder of 23.
Record the quotient 6 as the next digit in the result. 
Result so far: 1996.0
If we take 234 away from 257, we end up with 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 39

Going ahead to step 6:
If we divide 231 by 39, we get 5 and a remainder of 36.
Put 5 as the next digit of the answer. 
Result so far: 19965.0
Subtracting 195 from 231 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
If we divide 360 by 39, we get 9 and a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 19965.9
If we subtract 351 from 360, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 8:
When dividing 90 by 39, we get 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 19965.92
Subtracting 78 from 90 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
When dividing 120 by 39, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 19965.923
The remainder is 3 after subtracting 117 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
39 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 19965.923
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
39 can be fit into 300 7 times, resulting in a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 19965.92307
The remainder is 27 after subtracting 273 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 12:
If we divide 270 by 39, we get 6 and a remainder of 36.
The next digit of our result is 6. 
Result so far: 19965.923076
If we subtract 234 from 270, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 13:
39 can be fit into 360 9 times, resulting in a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 19965.9230769
The remainder is 9 after subtracting 351 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 14:
The number 39 fits into 90 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 19965.92307692
Deduct 78 from 90 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 19965.92307692, and the remainder is 1.2e-08.
