21508666 ÷ 460 
We want to divide 21508666 by 460.

Let's proceed to step 1:
460 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our 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 / 460

Step 2:
460 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 460

Let's proceed to step 3:
460 can be fit into 215 0 times, resulting in a remainder of 215.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 215 to get 215.
Take the next digit (0) from the dividend and append it to 215, then repeat: 2150 / 460

Advancing to step 4:
460 can be fit into 2150 4 times, resulting in a remainder of 310.
The next digit of our result is 4. 
Result so far: 4.0
If we take 1840 away from 2150, we end up with 310.
Grab the next digit (8) from the dividend, add it to 310, then carry on: 3108 / 460

On to step 5:
460 can be fit into 3108 6 times, resulting in a remainder of 348.
Write down 6 as next digit of the result. 
Result so far: 46.0
The remainder is 348 after subtracting 2760 from 3108.
Bring next digit (6) of the dividend behind the 348 and repeat the process: 3486 / 460

Going ahead to step 6:
If we divide 3486 by 460, we get 7 and a remainder of 266.
Use 7 as the next digit of our solution. 
Result so far: 467.0
If we take 3220 away from 3486, we end up with 266.
Grab the next digit (6) from the dividend, add it to 266, then carry on: 2666 / 460

Going ahead to step 7:
2666 divided by 460 is 5 with a remainder of 366.
The next digit of our result is 5. 
Result so far: 4675.0
The remainder is 366 after subtracting 2300 from 2666.
Bring next digit (6) of the dividend behind the 366 and repeat the process: 3666 / 460

Step 8:
The number 460 fits into 3666 7 times, leaving a remainder of 446.
The next digit of our result is 7. 
Result so far: 46757.0
Deduct 3220 from 3666 and we're left with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Advancing to step 9:
460 can be fit into 4460 9 times, resulting in a remainder of 320.
The number 9 becomes the next digit in our result. 
Result so far: 46757.9
If we subtract 4140 from 4460, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 10:
3200 divided by 460 is 6 with a remainder of 440.
Write down 6 as next digit of the result. 
Result so far: 46757.96
Subtract 2760 from 3200 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 11:
4400 divided by 460 is 9 with a remainder of 260.
Use 9 as the next digit of our solution. 
Result so far: 46757.969
Subtract 4140 from 4400 to 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.

Advancing to step 12:
The number 460 fits into 2600 5 times, leaving a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 46757.9695
The remainder is 300 after subtracting 2300 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 13:
460 goes into 3000 6 times with a remainder of 240.
Write down 6 as next digit of the result. 
Result so far: 46757.96956
If we take 2760 away from 3000, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 14:
460 can be fit into 2400 5 times, resulting in a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 46757.969565
Deduct 2300 from 2400 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 15:
If we divide 1000 by 460, we get 2 and a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 46757.9695652
If we take 920 away from 1000, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 16:
When dividing 800 by 460, we get 1 with a remainder of 340.
The number 1 becomes the next digit in our result. 
Result so far: 46757.96956521
The remainder is 340 after subtracting 460 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The final result is 46757.96956521 with a remainder of 3.4e-07.
