16424477 ÷ 780 
We're looking to find how many times 780 goes into 16424477.

Advancing to step 1:
The number 780 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 780

Moving on to step 2:
If we divide 16 by 780, we get 0 and a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 780

Going ahead to step 3:
The number 780 fits into 164 0 times, leaving a remainder of 164.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 164, we get 164.
Bring next digit (2) of the dividend behind the 164 and repeat the process: 1642 / 780

Let's proceed to step 4:
1642 divided by 780 is 2 with a remainder of 82.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1560 from 1642 and we're left with 82.
Append the next digit (4) from the dividend to 82 and continue with: 824 / 780

Step 5:
824 divided by 780 is 1 with a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtracting 780 from 824 leaves us with 44.
Append the next digit (4) from the dividend to 44 and continue with: 444 / 780

Let's proceed to step 6:
The number 780 fits into 444 0 times, leaving a remainder of 444.
Record the quotient 0 as the next digit in the result. 
Result so far: 210.0
If we subtract 0 from 444, we get 444.
Take the next digit (7) from the dividend and append it to 444, then repeat: 4447 / 780

Moving on to step 7:
4447 divided by 780 is 5 with a remainder of 547.
Put 5 as the next digit of the answer. 
Result so far: 2105.0
If we subtract 3900 from 4447, we get 547.
Fetch the next digit (7) from the dividend, attach it to 547 and continue: 5477 / 780

Going ahead to step 8:
The number 780 fits into 5477 7 times, leaving a remainder of 17.
The next digit of our result is 7. 
Result so far: 21057.0
Deduct 5460 from 5477 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 9:
If we divide 170 by 780, we get 0 and a remainder of 170.
The next digit of our result is 0. 
Result so far: 21057.0
The remainder is 170 after subtracting 0 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 10:
When dividing 1700 by 780, we get 2 with a remainder of 140.
Put 2 as the next digit of the answer. 
Result so far: 21057.02
Subtract 1560 from 1700 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.

Going ahead to step 11:
The number 780 fits into 1400 1 times, leaving a remainder of 620.
Use 1 as the next digit of our solution. 
Result so far: 21057.021
The remainder is 620 after subtracting 780 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 12:
If we divide 6200 by 780, we get 7 and a remainder of 740.
Put 7 as the next digit of the answer. 
Result so far: 21057.0217
Subtract 5460 from 6200 to get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Step 13:
The number 780 fits into 7400 9 times, leaving a remainder of 380.
The next digit of our result is 9. 
Result so far: 21057.02179
Subtract 7020 from 7400 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 14:
780 can be fit into 3800 4 times, resulting in a remainder of 680.
Put 4 as the next digit of the answer. 
Result so far: 21057.021794
Deduct 3120 from 3800 and we're left with 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 15:
780 can be fit into 6800 8 times, resulting in a remainder of 560.
Write down 8 as next digit of the result. 
Result so far: 21057.0217948
Subtracting 6240 from 6800 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 16:
5600 divided by 780 is 7 with a remainder of 140.
Record the quotient 7 as the next digit in the result. 
Result so far: 21057.02179487
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.

The quotient of the division is 21057.02179487, and the remainder is 1.4e-07.
