We're dividing 19571084 by 780 
Our goal is to divide 19571084 by 780.

On to step 1:
780 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 780

Advancing to step 2:
19 divided by 780 is 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 780

Moving on to step 3:
780 goes into 195 0 times with a remainder of 195.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 195, we end up with 195.
Append the next digit (7) from the dividend to 195 and continue with: 1957 / 780

Going ahead to step 4:
When dividing 1957 by 780, we get 2 with a remainder of 397.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1560 from 1957 leaves us with 397.
Include the next digit (1) from the dividend after 397, then repeat: 3971 / 780

Going ahead to step 5:
When dividing 3971 by 780, we get 5 with a remainder of 71.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Deduct 3900 from 3971 and we're left with 71.
Include the next digit (0) from the dividend after 71, then repeat: 710 / 780

Going ahead to step 6:
If we divide 710 by 780, we get 0 and a remainder of 710.
Record the quotient 0 as the next digit in the result. 
Result so far: 250.0
If we subtract 0 from 710, we get 710.
Include the next digit (8) from the dividend after 710, then repeat: 7108 / 780

Let's proceed to step 7:
The number 780 fits into 7108 9 times, leaving a remainder of 88.
Write down 9 as next digit of the result. 
Result so far: 2509.0
Subtract 7020 from 7108 to get 88.
Grab the next digit (4) from the dividend, add it to 88, then carry on: 884 / 780

Moving on to step 8:
If we divide 884 by 780, we get 1 and a remainder of 104.
The next digit of our result is 1. 
Result so far: 25091.0
Deduct 780 from 884 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 9:
The number 780 fits into 1040 1 times, leaving a remainder of 260.
Record the quotient 1 as the next digit in the result. 
Result so far: 25091.1
Deduct 780 from 1040 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 10:
The number 780 fits into 2600 3 times, leaving a remainder of 260.
The next digit of our result is 3. 
Result so far: 25091.13
Subtracting 2340 from 2600 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 11:
780 goes into 2600 3 times with a remainder of 260.
Put 3 as the next digit of the answer. 
Result so far: 25091.133
The remainder is 260 after subtracting 2340 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Our division results in 25091.133 with a remaining 0.026.
