Let's divide 12052620 by 780
We want to divide 12052620 by 780.

Step 1:
The number 780 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 780

On to step 2:
When dividing 12 by 780, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 780

Moving on to step 3:
When dividing 120 by 780, we get 0 with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 120 after subtracting 0 from 120.
Append the next digit (5) from the dividend to 120 and continue with: 1205 / 780

Let's proceed to step 4:
780 goes into 1205 1 times with a remainder of 425.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 780 from 1205, we get 425.
Append the next digit (2) from the dividend to 425 and continue with: 4252 / 780

Going ahead to step 5:
4252 divided by 780 is 5 with a remainder of 352.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 3900 away from 4252, we end up with 352.
Take the next digit (6) from the dividend and append it to 352, then repeat: 3526 / 780

Moving on to step 6:
3526 divided by 780 is 4 with a remainder of 406.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
If we subtract 3120 from 3526, we get 406.
Bring next digit (2) of the dividend behind the 406 and repeat the process: 4062 / 780

Going ahead to step 7:
If we divide 4062 by 780, we get 5 and a remainder of 162.
Write down 5 as next digit of the result. 
Result so far: 1545.0
If we take 3900 away from 4062, we end up with 162.
Bring next digit (0) of the dividend behind the 162 and repeat the process: 1620 / 780

Going ahead to step 8:
If we divide 1620 by 780, we get 2 and a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 15452.0
The remainder is 60 after subtracting 1560 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
780 goes into 600 0 times with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 15452.0
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 10:
6000 divided by 780 is 7 with a remainder of 540.
Put 7 as the next digit of the answer. 
Result so far: 15452.07
Subtract 5460 from 6000 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 11:
5400 divided by 780 is 6 with a remainder of 720.
The number 6 becomes the next digit in our result. 
Result so far: 15452.076
Subtract 4680 from 5400 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 12:
If we divide 7200 by 780, we get 9 and a remainder of 180.
Record the quotient 9 as the next digit in the result. 
Result so far: 15452.0769
Deduct 7020 from 7200 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 13:
If we divide 1800 by 780, we get 2 and a remainder of 240.
The next digit of our result is 2. 
Result so far: 15452.07692
Subtracting 1560 from 1800 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 14:
When dividing 2400 by 780, we get 3 with a remainder of 60.
The next digit of our result is 3. 
Result so far: 15452.076923
Subtract 2340 from 2400 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 15:
780 goes into 600 0 times with a remainder of 600.
The next digit of our result is 0. 
Result so far: 15452.076923
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 16:
6000 divided by 780 is 7 with a remainder of 540.
Put 7 as the next digit of the answer. 
Result so far: 15452.07692307
Subtract 5460 from 6000 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

The final outcome is 15452.07692307, with a leftover of 5.4e-07.
