We look at the division of 21710195 by 766 
Let's see how many times 766 fits into 21710195.

Moving on to step 1:
When dividing 2 by 766, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 766

Moving on to step 2:
21 divided by 766 is 0 with 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.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 766

Let's proceed to step 3:
766 goes into 217 0 times with a remainder of 217.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 217 to get 217.
Take the next digit (1) from the dividend and append it to 217, then repeat: 2171 / 766

On to step 4:
766 goes into 2171 2 times with a remainder of 639.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1532 from 2171 and we're left with 639.
Fetch the next digit (0) from the dividend, attach it to 639 and continue: 6390 / 766

Going ahead to step 5:
The number 766 fits into 6390 8 times, leaving a remainder of 262.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we subtract 6128 from 6390, we get 262.
Bring next digit (1) of the dividend behind the 262 and repeat the process: 2621 / 766

Going ahead to step 6:
The number 766 fits into 2621 3 times, leaving a remainder of 323.
The next digit of our result is 3. 
Result so far: 283.0
If we subtract 2298 from 2621, we get 323.
Fetch the next digit (9) from the dividend, attach it to 323 and continue: 3239 / 766

Moving on to step 7:
When dividing 3239 by 766, we get 4 with a remainder of 175.
Put 4 as the next digit of the answer. 
Result so far: 2834.0
If we take 3064 away from 3239, we end up with 175.
Grab the next digit (5) from the dividend, add it to 175, then carry on: 1755 / 766

Going ahead to step 8:
766 goes into 1755 2 times with a remainder of 223.
Record the quotient 2 as the next digit in the result. 
Result so far: 28342.0
Deduct 1532 from 1755 and we're left with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Step 9:
If we divide 2230 by 766, we get 2 and a remainder of 698.
Write down 2 as next digit of the result. 
Result so far: 28342.2
If we take 1532 away from 2230, we end up with 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Step 10:
766 goes into 6980 9 times with a remainder of 86.
Put 9 as the next digit of the answer. 
Result so far: 28342.29
If we take 6894 away from 6980, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 11:
766 can be fit into 860 1 times, resulting in a remainder of 94.
Use 1 as the next digit of our solution. 
Result so far: 28342.291
The remainder is 94 after subtracting 766 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 12:
940 divided by 766 is 1 with a remainder of 174.
The number 1 becomes the next digit in our result. 
Result so far: 28342.2911
The remainder is 174 after subtracting 766 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Our division results in 28342.2911 with a remaining 0.00174.
