We look at the division of 21174894 by 780 
Our goal is to divide 21174894 by 780.

Moving on to step 1:
780 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 780

Let's proceed to step 2:
If we divide 21 by 780, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 780

Going ahead to step 3:
780 can be fit into 211 0 times, resulting in a remainder of 211.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 211 leaves us with 211.
Bring next digit (7) of the dividend behind the 211 and repeat the process: 2117 / 780

Advancing to step 4:
When dividing 2117 by 780, we get 2 with a remainder of 557.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 1560 away from 2117, we end up with 557.
Take the next digit (4) from the dividend and append it to 557, then repeat: 5574 / 780

Moving on to step 5:
5574 divided by 780 is 7 with a remainder of 114.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we subtract 5460 from 5574, we get 114.
Grab the next digit (8) from the dividend, add it to 114, then carry on: 1148 / 780

Let's proceed to step 6:
When dividing 1148 by 780, we get 1 with a remainder of 368.
Use 1 as the next digit of our solution. 
Result so far: 271.0
Subtracting 780 from 1148 leaves us with 368.
Fetch the next digit (9) from the dividend, attach it to 368 and continue: 3689 / 780

Going ahead to step 7:
780 goes into 3689 4 times with a remainder of 569.
Record the quotient 4 as the next digit in the result. 
Result so far: 2714.0
Subtract 3120 from 3689 to get 569.
Take the next digit (4) from the dividend and append it to 569, then repeat: 5694 / 780

Moving on to step 8:
The number 780 fits into 5694 7 times, leaving a remainder of 234.
The number 7 becomes the next digit in our result. 
Result so far: 27147.0
If we take 5460 away from 5694, we end up with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 9:
780 can be fit into 2340 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 27147.3
If we subtract 2340 from 2340, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
0 divided by 780 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 27147.3
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
When dividing 0 by 780, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 27147.3
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 27147.3, with a leftover of 0.0.
