21597007 ÷ 784 
We want to figure out the number of times 21597007 can be divided by 784.

Moving on to step 1:
784 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 784

Moving on to step 2:
21 divided by 784 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 784

On to step 3:
784 can be fit into 215 0 times, resulting in a remainder of 215.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 215 after subtracting 0 from 215.
Include the next digit (9) from the dividend after 215, then repeat: 2159 / 784

Let's proceed to step 4:
784 can be fit into 2159 2 times, resulting in a remainder of 591.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1568 from 2159 and we're left with 591.
Include the next digit (7) from the dividend after 591, then repeat: 5917 / 784

On to step 5:
When dividing 5917 by 784, we get 7 with a remainder of 429.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we subtract 5488 from 5917, we get 429.
Include the next digit (0) from the dividend after 429, then repeat: 4290 / 784

Advancing to step 6:
4290 divided by 784 is 5 with a remainder of 370.
Put 5 as the next digit of the answer. 
Result so far: 275.0
Subtract 3920 from 4290 to get 370.
Include the next digit (0) from the dividend after 370, then repeat: 3700 / 784

Let's proceed to step 7:
3700 divided by 784 is 4 with a remainder of 564.
The next digit of our result is 4. 
Result so far: 2754.0
The remainder is 564 after subtracting 3136 from 3700.
Grab the next digit (7) from the dividend, add it to 564, then carry on: 5647 / 784

Going ahead to step 8:
If we divide 5647 by 784, we get 7 and a remainder of 159.
Record the quotient 7 as the next digit in the result. 
Result so far: 27547.0
Subtract 5488 from 5647 to get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Step 9:
1590 divided by 784 is 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 27547.2
Deduct 1568 from 1590 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
220 divided by 784 is 0 with a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 27547.2
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 11:
784 goes into 2200 2 times with a remainder of 632.
The number 2 becomes the next digit in our result. 
Result so far: 27547.202
Subtract 1568 from 2200 to get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Step 12:
The number 784 fits into 6320 8 times, leaving a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 27547.2028
Subtracting 6272 from 6320 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 13:
784 goes into 480 0 times with a remainder of 480.
Put 0 as the next digit of the answer. 
Result so far: 27547.2028
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 14:
The number 784 fits into 4800 6 times, leaving a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 27547.202806
If we take 4704 away from 4800, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 15:
960 divided by 784 is 1 with a remainder of 176.
Put 1 as the next digit of the answer. 
Result so far: 27547.2028061
If we subtract 784 from 960, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 16:
784 can be fit into 1760 2 times, resulting in a remainder of 192.
The number 2 becomes the next digit in our result. 
Result so far: 27547.20280612
If we subtract 1568 from 1760, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

After the division, we end up with 27547.20280612 and a remainder of 1.92e-07.
