21664616 ÷ 535 
We're looking to find how many times 535 goes into 21664616.

On to step 1:
535 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 535

On to step 2:
If we divide 21 by 535, we get 0 and a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 535

On to step 3:
If we divide 216 by 535, we get 0 and a remainder of 216.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 216 to get 216.
Fetch the next digit (6) from the dividend, attach it to 216 and continue: 2166 / 535

Moving on to step 4:
535 goes into 2166 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 2140 from 2166 to get 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 535

Step 5:
When dividing 264 by 535, we get 0 with a remainder of 264.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Subtract 0 from 264 to get 264.
Grab the next digit (6) from the dividend, add it to 264, then carry on: 2646 / 535

Going ahead to step 6:
535 goes into 2646 4 times with a remainder of 506.
The next digit of our result is 4. 
Result so far: 404.0
Deduct 2140 from 2646 and we're left with 506.
Take the next digit (1) from the dividend and append it to 506, then repeat: 5061 / 535

Advancing to step 7:
If we divide 5061 by 535, we get 9 and a remainder of 246.
The next digit of our result is 9. 
Result so far: 4049.0
If we take 4815 away from 5061, we end up with 246.
Append the next digit (6) from the dividend to 246 and continue with: 2466 / 535

On to step 8:
When dividing 2466 by 535, we get 4 with a remainder of 326.
Record the quotient 4 as the next digit in the result. 
Result so far: 40494.0
Subtracting 2140 from 2466 leaves us with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Moving on to step 9:
When dividing 3260 by 535, we get 6 with a remainder of 50.
The next digit of our result is 6. 
Result so far: 40494.6
The remainder is 50 after subtracting 3210 from 3260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
535 can be fit into 500 0 times, resulting in a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 40494.6
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 11:
535 goes into 5000 9 times with a remainder of 185.
Write down 9 as next digit of the result. 
Result so far: 40494.609
Subtract 4815 from 5000 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 12:
535 goes into 1850 3 times with a remainder of 245.
The number 3 becomes the next digit in our result. 
Result so far: 40494.6093
If we take 1605 away from 1850, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Advancing to step 13:
When dividing 2450 by 535, we get 4 with a remainder of 310.
Record the quotient 4 as the next digit in the result. 
Result so far: 40494.60934
Subtracting 2140 from 2450 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 14:
535 goes into 3100 5 times with a remainder of 425.
The number 5 becomes the next digit in our result. 
Result so far: 40494.609345
Deduct 2675 from 3100 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Going ahead to step 15:
When dividing 4250 by 535, we get 7 with a remainder of 505.
Write down 7 as next digit of the result. 
Result so far: 40494.6093457
The remainder is 505 after subtracting 3745 from 4250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Step 16:
The number 535 fits into 5050 9 times, leaving a remainder of 235.
Put 9 as the next digit of the answer. 
Result so far: 40494.60934579
Subtracting 4815 from 5050 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

The final result is 40494.60934579 with a remainder of 2.35e-07.
