771371 ÷ 39 
We want to figure out the number of times 771371 can be divided by 39.

Step 1:
39 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 39

Moving on to step 2:
77 divided by 39 is 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 39 from 77 leaves us with 38.
Fetch the next digit (1) from the dividend, attach it to 38 and continue: 381 / 39

Going ahead to step 3:
When dividing 381 by 39, we get 9 with a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we subtract 351 from 381, we get 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 39

Advancing to step 4:
When dividing 303 by 39, we get 7 with a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 197.0
Deduct 273 from 303 and we're left with 30.
Take the next digit (7) from the dividend and append it to 30, then repeat: 307 / 39

Step 5:
If we divide 307 by 39, we get 7 and a remainder of 34.
The next digit of our result is 7. 
Result so far: 1977.0
If we subtract 273 from 307, we get 34.
Include the next digit (1) from the dividend after 34, then repeat: 341 / 39

Moving on to step 6:
If we divide 341 by 39, we get 8 and a remainder of 29.
Put 8 as the next digit of the answer. 
Result so far: 19778.0
The remainder is 29 after subtracting 312 from 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
When dividing 290 by 39, we get 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 19778.7
Deduct 273 from 290 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 8:
39 goes into 170 4 times with a remainder of 14.
The next digit of our result is 4. 
Result so far: 19778.74
Subtract 156 from 170 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
The number 39 fits into 140 3 times, leaving a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 19778.743
If we take 117 away from 140, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 10:
The number 39 fits into 230 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 19778.7435
Deduct 195 from 230 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 11:
350 divided by 39 is 8 with a remainder of 38.
The next digit of our result is 8. 
Result so far: 19778.74358
Deduct 312 from 350 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 12:
39 goes into 380 9 times with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 19778.743589
Subtracting 351 from 380 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 13:
The number 39 fits into 290 7 times, leaving a remainder of 17.
The next digit of our result is 7. 
Result so far: 19778.7435897
If we subtract 273 from 290, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 14:
If we divide 170 by 39, we get 4 and a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 19778.74358974
Deduct 156 from 170 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 19778.74358974, with a leftover of 1.4e-08.
