We're dividing 21769685 by 510 
Let's see how many times 510 fits into 21769685.

Going ahead to step 1:
The number 510 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 510

On to step 2:
When dividing 21 by 510, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 510

Advancing to step 3:
If we divide 217 by 510, we get 0 and a remainder of 217.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 217 leaves us with 217.
Append the next digit (6) from the dividend to 217 and continue with: 2176 / 510

Step 4:
When dividing 2176 by 510, we get 4 with a remainder of 136.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 2040 from 2176, we get 136.
Bring next digit (9) of the dividend behind the 136 and repeat the process: 1369 / 510

Advancing to step 5:
1369 divided by 510 is 2 with a remainder of 349.
The next digit of our result is 2. 
Result so far: 42.0
If we take 1020 away from 1369, we end up with 349.
Append the next digit (6) from the dividend to 349 and continue with: 3496 / 510

Step 6:
510 can be fit into 3496 6 times, resulting in a remainder of 436.
Use 6 as the next digit of our solution. 
Result so far: 426.0
If we subtract 3060 from 3496, we get 436.
Append the next digit (8) from the dividend to 436 and continue with: 4368 / 510

Step 7:
The number 510 fits into 4368 8 times, leaving a remainder of 288.
Use 8 as the next digit of our solution. 
Result so far: 4268.0
The remainder is 288 after subtracting 4080 from 4368.
Take the next digit (5) from the dividend and append it to 288, then repeat: 2885 / 510

Moving on to step 8:
The number 510 fits into 2885 5 times, leaving a remainder of 335.
The next digit of our result is 5. 
Result so far: 42685.0
Subtracting 2550 from 2885 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Going ahead to step 9:
The number 510 fits into 3350 6 times, leaving a remainder of 290.
The next digit of our result is 6. 
Result so far: 42685.6
If we take 3060 away from 3350, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 10:
510 goes into 2900 5 times with a remainder of 350.
The next digit of our result is 5. 
Result so far: 42685.65
The remainder is 350 after subtracting 2550 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 11:
510 goes into 3500 6 times with a remainder of 440.
Put 6 as the next digit of the answer. 
Result so far: 42685.656
Subtract 3060 from 3500 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 12:
If we divide 4400 by 510, we get 8 and a remainder of 320.
Put 8 as the next digit of the answer. 
Result so far: 42685.6568
If we take 4080 away from 4400, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 13:
510 can be fit into 3200 6 times, resulting in a remainder of 140.
The next digit of our result is 6. 
Result so far: 42685.65686
Subtract 3060 from 3200 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.

Let's proceed to step 14:
If we divide 1400 by 510, we get 2 and a remainder of 380.
Write down 2 as next digit of the result. 
Result so far: 42685.656862
Subtracting 1020 from 1400 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 15:
If we divide 3800 by 510, we get 7 and a remainder of 230.
Put 7 as the next digit of the answer. 
Result so far: 42685.6568627
Subtract 3570 from 3800 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 16:
510 goes into 2300 4 times with a remainder of 260.
Record the quotient 4 as the next digit in the result. 
Result so far: 42685.65686274
If we subtract 2040 from 2300, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The quotient of the division is 42685.65686274, and the remainder is 2.6e-07.
