We look at the division of 3910625 by 780 
We want to divide 3910625 by 780.

Going ahead to step 1:
If we divide 3 by 780, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 780

Advancing to step 2:
780 goes into 39 0 times with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 780

On to step 3:
The number 780 fits into 391 0 times, leaving a remainder of 391.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 391 after subtracting 0 from 391.
Take the next digit (0) from the dividend and append it to 391, then repeat: 3910 / 780

Step 4:
780 can be fit into 3910 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 10 after subtracting 3900 from 3910.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 780

On to step 5:
106 divided by 780 is 0 with a remainder of 106.
The next digit of our result is 0. 
Result so far: 50.0
The remainder is 106 after subtracting 0 from 106.
Bring next digit (2) of the dividend behind the 106 and repeat the process: 1062 / 780

Step 6:
When dividing 1062 by 780, we get 1 with a remainder of 282.
Write down 1 as next digit of the result. 
Result so far: 501.0
If we take 780 away from 1062, we end up with 282.
Bring next digit (5) of the dividend behind the 282 and repeat the process: 2825 / 780

Moving on to step 7:
780 can be fit into 2825 3 times, resulting in a remainder of 485.
The next digit of our result is 3. 
Result so far: 5013.0
The remainder is 485 after subtracting 2340 from 2825.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Step 8:
When dividing 4850 by 780, we get 6 with a remainder of 170.
Record the quotient 6 as the next digit in the result. 
Result so far: 5013.6
If we take 4680 away from 4850, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 9:
The number 780 fits into 1700 2 times, leaving a remainder of 140.
The next digit of our result is 2. 
Result so far: 5013.62
Deduct 1560 from 1700 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 10:
When dividing 1400 by 780, we get 1 with a remainder of 620.
Record the quotient 1 as the next digit in the result. 
Result so far: 5013.621
If we subtract 780 from 1400, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 11:
If we divide 6200 by 780, we get 7 and a remainder of 740.
Record the quotient 7 as the next digit in the result. 
Result so far: 5013.6217
Deduct 5460 from 6200 and we're left with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Moving on to step 12:
780 goes into 7400 9 times with a remainder of 380.
Write down 9 as next digit of the result. 
Result so far: 5013.62179
Subtracting 7020 from 7400 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 13:
780 can be fit into 3800 4 times, resulting in a remainder of 680.
The number 4 becomes the next digit in our result. 
Result so far: 5013.621794
If we subtract 3120 from 3800, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 14:
If we divide 6800 by 780, we get 8 and a remainder of 560.
Use 8 as the next digit of our solution. 
Result so far: 5013.6217948
Subtract 6240 from 6800 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 15:
When dividing 5600 by 780, we get 7 with a remainder of 140.
Record the quotient 7 as the next digit in the result. 
Result so far: 5013.62179487
Subtract 5460 from 5600 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Our division results in 5013.62179487 with a remaining 1.4e-07.
