We divide 779888 by 39
We're looking to find how many times 39 goes into 779888.

Let's proceed to step 1:
When dividing 7 by 39, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 39

Going ahead 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.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 39

Let's proceed to step 3:
If we divide 389 by 39, we get 9 and a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 351 from 389 to get 38.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 39

Let's proceed to step 4:
When dividing 388 by 39, we get 9 with a remainder of 37.
The next digit of our result is 9. 
Result so far: 199.0
If we subtract 351 from 388, we get 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 39

Moving on to step 5:
39 goes into 378 9 times with a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 1999.0
Subtract 351 from 378 to get 27.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 39

On to step 6:
278 divided by 39 is 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 19997.0
Deduct 273 from 278 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
39 can be fit into 50 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 19997.1
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
If we divide 110 by 39, we get 2 and a remainder of 32.
The next digit of our result is 2. 
Result so far: 19997.12
Deduct 78 from 110 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
39 goes into 320 8 times with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 19997.128
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
The number 39 fits into 80 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 19997.1282
The remainder is 2 after subtracting 78 from 80.
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 11:
20 divided by 39 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 19997.1282
If we subtract 0 from 20, we get 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 12:
39 goes into 200 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 19997.128205
If we subtract 195 from 200, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 13:
39 can be fit into 50 1 times, resulting in a remainder of 11.
The next digit of our result is 1. 
Result so far: 19997.1282051
Subtract 39 from 50 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 14:
110 divided by 39 is 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 19997.12820512
Subtracting 78 from 110 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 19997.12820512 with a remainder of 3.2e-08.
