We divide 780146 by 39
We want to divide 780146 by 39.

On to step 1:
7 divided by 39 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 39

Step 2:
39 can be fit into 78 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 78 from 78 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 39

Let's proceed to step 3:
39 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 0, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 39

Moving on to step 4:
39 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 200.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 39

Advancing to step 5:
If we divide 14 by 39, we get 0 and a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 2000.0
The remainder is 14 after subtracting 0 from 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 39

Moving on to step 6:
146 divided by 39 is 3 with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 20003.0
Subtract 117 from 146 to get 29.
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:
39 can be fit into 290 7 times, resulting in a remainder of 17.
The next digit of our result is 7. 
Result so far: 20003.7
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.

On 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: 20003.74
If we take 156 away from 170, we end up 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.

Going ahead to step 9:
When dividing 140 by 39, we get 3 with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 20003.743
Subtract 117 from 140 to get 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:
39 can be fit into 230 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 20003.7435
Subtracting 195 from 230 leaves us 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.

Going ahead to step 11:
If we divide 350 by 39, we get 8 and a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 20003.74358
Subtracting 312 from 350 leaves us 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.

Step 12:
The number 39 fits into 380 9 times, leaving a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 20003.743589
If we take 351 away from 380, we end up 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.

Going ahead to step 13:
When dividing 290 by 39, we get 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 20003.7435897
Subtract 273 from 290 to 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:
39 goes into 170 4 times with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 20003.74358974
If we subtract 156 from 170, we 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.

The final outcome is 20003.74358974, with a leftover of 1.4e-08.
