21760030 ÷ 418 
We want to figure out the number of times 21760030 can be divided by 418.

On to step 1:
418 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
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 418

On to step 2:
When dividing 21 by 418, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 418

Going ahead to step 3:
217 divided by 418 is 0 with a remainder of 217.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 217 after subtracting 0 from 217.
Include the next digit (6) from the dividend after 217, then repeat: 2176 / 418

On to step 4:
418 goes into 2176 5 times with a remainder of 86.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 2090 from 2176, we get 86.
Take the next digit (0) from the dividend and append it to 86, then repeat: 860 / 418

Moving on to step 5:
The number 418 fits into 860 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 52.0
If we subtract 836 from 860, we get 24.
Fetch the next digit (0) from the dividend, attach it to 24 and continue: 240 / 418

Moving on to step 6:
240 divided by 418 is 0 with a remainder of 240.
The next digit of our result is 0. 
Result so far: 520.0
Deduct 0 from 240 and we're left with 240.
Append the next digit (3) from the dividend to 240 and continue with: 2403 / 418

Step 7:
418 goes into 2403 5 times with a remainder of 313.
The number 5 becomes the next digit in our result. 
Result so far: 5205.0
Subtract 2090 from 2403 to get 313.
Append the next digit (0) from the dividend to 313 and continue with: 3130 / 418

Step 8:
3130 divided by 418 is 7 with a remainder of 204.
The next digit of our result is 7. 
Result so far: 52057.0
If we subtract 2926 from 3130, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 9:
The number 418 fits into 2040 4 times, leaving a remainder of 368.
The next digit of our result is 4. 
Result so far: 52057.4
If we take 1672 away from 2040, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 10:
418 goes into 3680 8 times with a remainder of 336.
Record the quotient 8 as the next digit in the result. 
Result so far: 52057.48
If we take 3344 away from 3680, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 11:
The number 418 fits into 3360 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 52057.488
If we take 3344 away from 3360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 52057.488 with a remainder of 0.0016.
