We look at the division of 771730 by 39 
Our goal is to divide 771730 by 39.

Step 1:
If we divide 7 by 39, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 39

Step 2:
When dividing 77 by 39, we get 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 39 from 77 to get 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 39

On to step 3:
The number 39 fits into 381 9 times, leaving a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we take 351 away from 381, we end up with 30.
Take the next digit (7) from the dividend and append it to 30, then repeat: 307 / 39

On to step 4:
The number 39 fits into 307 7 times, leaving a remainder of 34.
The next digit of our result is 7. 
Result so far: 197.0
Subtracting 273 from 307 leaves us with 34.
Append the next digit (3) from the dividend to 34 and continue with: 343 / 39

Moving on to step 5:
343 divided by 39 is 8 with a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 1978.0
Subtract 312 from 343 to get 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 39

Let's proceed to step 6:
39 goes into 310 7 times with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 19787.0
If we subtract 273 from 310, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 7:
When dividing 370 by 39, we get 9 with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 19787.9
Deduct 351 from 370 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 8:
If we divide 190 by 39, we get 4 and a remainder of 34.
The next digit of our result is 4. 
Result so far: 19787.94
Subtracting 156 from 190 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 9:
When dividing 340 by 39, we get 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 19787.948
If we subtract 312 from 340, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
The number 39 fits into 280 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 19787.9487
If we subtract 273 from 280, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 11:
If we divide 70 by 39, we get 1 and a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 19787.94871
The remainder is 31 after subtracting 39 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 12:
39 goes into 310 7 times with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 19787.948717
If we subtract 273 from 310, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 13:
39 goes into 370 9 times with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 19787.9487179
The remainder is 19 after subtracting 351 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 14:
The number 39 fits into 190 4 times, leaving a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 19787.94871794
Subtract 156 from 190 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 19787.94871794 with a balance of 3.4e-08.
