We're dividing 770236 by 39 
Let's see how many times 39 fits into 770236.

Going ahead to step 1:
If we divide 7 by 39, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 39

Moving on to step 2:
When dividing 77 by 39, we get 1 with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 39 from 77 and we're left with 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 39

Going ahead to step 3:
The number 39 fits into 380 9 times, leaving a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we take 351 away from 380, we end up with 29.
Grab the next digit (2) from the dividend, add it to 29, then carry on: 292 / 39

Moving on to step 4:
292 divided by 39 is 7 with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 197.0
Subtracting 273 from 292 leaves us with 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 39

Moving on to step 5:
When dividing 193 by 39, we get 4 with a remainder of 37.
The next digit of our result is 4. 
Result so far: 1974.0
Subtract 156 from 193 to get 37.
Append the next digit (6) from the dividend to 37 and continue with: 376 / 39

Going ahead to step 6:
When dividing 376 by 39, we get 9 with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 19749.0
Subtract 351 from 376 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
39 goes into 250 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 19749.6
The remainder is 16 after subtracting 234 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
39 goes into 160 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 19749.64
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
39 goes into 40 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 19749.641
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
10 divided by 39 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 19749.641
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
100 divided by 39 is 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 19749.64102
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
39 goes into 220 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 19749.641025
If we subtract 195 from 220, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 13:
39 can be fit into 250 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 19749.6410256
If we subtract 234 from 250, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
160 divided by 39 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 19749.64102564
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 19749.64102564 and a remainder of 4e-09.
