763764 divided by 39 
Our goal is to divide 763764 by 39.

Step 1:
When dividing 7 by 39, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 39

On to step 2:
39 can be fit into 76 1 times, resulting in a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 39 away from 76, we end up with 37.
Append the next digit (3) from the dividend to 37 and continue with: 373 / 39

On to step 3:
373 divided by 39 is 9 with a remainder of 22.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 351 from 373 leaves us with 22.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 39

Let's proceed to step 4:
39 goes into 227 5 times with a remainder of 32.
Use 5 as the next digit of our solution. 
Result so far: 195.0
Deduct 195 from 227 and we're left with 32.
Include the next digit (6) from the dividend after 32, then repeat: 326 / 39

Let's proceed to step 5:
If we divide 326 by 39, we get 8 and a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 1958.0
Subtract 312 from 326 to get 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 39

Step 6:
144 divided by 39 is 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 19583.0
Deduct 117 from 144 and we're left with 27.
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 7:
39 can be fit into 270 6 times, resulting in a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 19583.6
The remainder is 36 after subtracting 234 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
360 divided by 39 is 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 19583.69
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.

On to step 9:
The number 39 fits into 90 2 times, leaving a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 19583.692
Subtract 78 from 90 to get 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 10:
120 divided by 39 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 19583.6923
Subtracting 117 from 120 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
39 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 19583.6923
If we subtract 0 from 30, we 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.

On to step 12:
39 goes into 300 7 times with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 19583.692307
Deduct 273 from 300 and we're left with 27.
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 13:
270 divided by 39 is 6 with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 19583.6923076
The remainder is 36 after subtracting 234 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 14:
360 divided by 39 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 19583.69230769
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.

The quotient of the division is 19583.69230769, and the remainder is 9e-09.
