Let's divide 21660605 by 769
Our goal is to divide 21660605 by 769.

Going ahead to step 1:
2 divided by 769 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 769

Advancing to step 2:
If we divide 21 by 769, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 769

Let's proceed to step 3:
216 divided by 769 is 0 with a remainder of 216.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 216 leaves us with 216.
Include the next digit (6) from the dividend after 216, then repeat: 2166 / 769

Moving on to step 4:
769 can be fit into 2166 2 times, resulting in a remainder of 628.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1538 from 2166 and we're left with 628.
Include the next digit (0) from the dividend after 628, then repeat: 6280 / 769

Step 5:
The number 769 fits into 6280 8 times, leaving a remainder of 128.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 6152 from 6280 leaves us with 128.
Fetch the next digit (6) from the dividend, attach it to 128 and continue: 1286 / 769

Step 6:
The number 769 fits into 1286 1 times, leaving a remainder of 517.
Put 1 as the next digit of the answer. 
Result so far: 281.0
The remainder is 517 after subtracting 769 from 1286.
Fetch the next digit (0) from the dividend, attach it to 517 and continue: 5170 / 769

Step 7:
5170 divided by 769 is 6 with a remainder of 556.
Write down 6 as next digit of the result. 
Result so far: 2816.0
The remainder is 556 after subtracting 4614 from 5170.
Include the next digit (5) from the dividend after 556, then repeat: 5565 / 769

On to step 8:
5565 divided by 769 is 7 with a remainder of 182.
Use 7 as the next digit of our solution. 
Result so far: 28167.0
If we take 5383 away from 5565, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Advancing to step 9:
769 can be fit into 1820 2 times, resulting in a remainder of 282.
The number 2 becomes the next digit in our result. 
Result so far: 28167.2
If we subtract 1538 from 1820, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 10:
769 can be fit into 2820 3 times, resulting in a remainder of 513.
The next digit of our result is 3. 
Result so far: 28167.23
The remainder is 513 after subtracting 2307 from 2820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Step 11:
When dividing 5130 by 769, we get 6 with a remainder of 516.
Write down 6 as next digit of the result. 
Result so far: 28167.236
If we take 4614 away from 5130, we end up with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 12:
5160 divided by 769 is 6 with a remainder of 546.
Record the quotient 6 as the next digit in the result. 
Result so far: 28167.2366
Deduct 4614 from 5160 and we're left with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

After the division, we end up with 28167.2366 and a remainder of 0.00546.
