We look at the division of 19971681 by 780 
We want to figure out the number of times 19971681 can be divided by 780.

On to step 1:
780 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 780

Let's proceed to step 2:
The number 780 fits into 19 0 times, leaving a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 780

Moving on to step 3:
780 can be fit into 199 0 times, resulting in a remainder of 199.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 199, we end up with 199.
Take the next digit (7) from the dividend and append it to 199, then repeat: 1997 / 780

Let's proceed to step 4:
The number 780 fits into 1997 2 times, leaving a remainder of 437.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1560 from 1997 to get 437.
Fetch the next digit (1) from the dividend, attach it to 437 and continue: 4371 / 780

Step 5:
When dividing 4371 by 780, we get 5 with a remainder of 471.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we subtract 3900 from 4371, we get 471.
Bring next digit (6) of the dividend behind the 471 and repeat the process: 4716 / 780

Step 6:
When dividing 4716 by 780, we get 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 256.0
If we take 4680 away from 4716, we end up with 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 780

Step 7:
780 goes into 368 0 times with a remainder of 368.
Put 0 as the next digit of the answer. 
Result so far: 2560.0
If we subtract 0 from 368, we get 368.
Take the next digit (1) from the dividend and append it to 368, then repeat: 3681 / 780

Going ahead to step 8:
The number 780 fits into 3681 4 times, leaving a remainder of 561.
Use 4 as the next digit of our solution. 
Result so far: 25604.0
If we take 3120 away from 3681, we end up with 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

On to step 9:
5610 divided by 780 is 7 with a remainder of 150.
Write down 7 as next digit of the result. 
Result so far: 25604.7
Subtract 5460 from 5610 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 10:
If we divide 1500 by 780, we get 1 and a remainder of 720.
Put 1 as the next digit of the answer. 
Result so far: 25604.71
If we take 780 away from 1500, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 11:
When dividing 7200 by 780, we get 9 with a remainder of 180.
The next digit of our result is 9. 
Result so far: 25604.719
If we subtract 7020 from 7200, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 12:
780 goes into 1800 2 times with a remainder of 240.
Use 2 as the next digit of our solution. 
Result so far: 25604.7192
The remainder is 240 after subtracting 1560 from 1800.
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 13:
When dividing 2400 by 780, we get 3 with a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 25604.71923
Subtracting 2340 from 2400 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
780 goes into 600 0 times with a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 25604.71923
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.

Moving on to step 15:
When dividing 6000 by 780, we get 7 with a remainder of 540.
The number 7 becomes the next digit in our result. 
Result so far: 25604.7192307
If we take 5460 away from 6000, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Let's proceed to step 16:
780 goes into 5400 6 times with a remainder of 720.
Write down 6 as next digit of the result. 
Result so far: 25604.71923076
If we subtract 4680 from 5400, we 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.

After the division, we end up with 25604.71923076 and a remainder of 7.2e-07.
