We divide 21212159 by 535
Our goal is to divide 21212159 by 535.

Moving on to step 1:
2 divided by 535 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 535

Going ahead to step 2:
The number 535 fits into 21 0 times, leaving 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.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 535

Step 3:
When dividing 212 by 535, we get 0 with a remainder of 212.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 212, we get 212.
Bring next digit (1) of the dividend behind the 212 and repeat the process: 2121 / 535

Step 4:
535 goes into 2121 3 times with a remainder of 516.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 1605 from 2121 and we're left with 516.
Take the next digit (2) from the dividend and append it to 516, then repeat: 5162 / 535

Step 5:
5162 divided by 535 is 9 with a remainder of 347.
The next digit of our result is 9. 
Result so far: 39.0
If we subtract 4815 from 5162, we get 347.
Include the next digit (1) from the dividend after 347, then repeat: 3471 / 535

Moving on to step 6:
535 goes into 3471 6 times with a remainder of 261.
The number 6 becomes the next digit in our result. 
Result so far: 396.0
Subtracting 3210 from 3471 leaves us with 261.
Grab the next digit (5) from the dividend, add it to 261, then carry on: 2615 / 535

Going ahead to step 7:
2615 divided by 535 is 4 with a remainder of 475.
Write down 4 as next digit of the result. 
Result so far: 3964.0
If we take 2140 away from 2615, we end up with 475.
Append the next digit (9) from the dividend to 475 and continue with: 4759 / 535

Step 8:
If we divide 4759 by 535, we get 8 and a remainder of 479.
Write down 8 as next digit of the result. 
Result so far: 39648.0
The remainder is 479 after subtracting 4280 from 4759.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Moving on to step 9:
When dividing 4790 by 535, we get 8 with a remainder of 510.
Put 8 as the next digit of the answer. 
Result so far: 39648.8
Subtracting 4280 from 4790 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 10:
The number 535 fits into 5100 9 times, leaving a remainder of 285.
Put 9 as the next digit of the answer. 
Result so far: 39648.89
Subtracting 4815 from 5100 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 11:
535 can be fit into 2850 5 times, resulting in a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 39648.895
Subtract 2675 from 2850 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 12:
535 can be fit into 1750 3 times, resulting in a remainder of 145.
Put 3 as the next digit of the answer. 
Result so far: 39648.8953
Subtract 1605 from 1750 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 13:
When dividing 1450 by 535, we get 2 with a remainder of 380.
Use 2 as the next digit of our solution. 
Result so far: 39648.89532
If we take 1070 away from 1450, we end up 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.

On to step 14:
If we divide 3800 by 535, we get 7 and a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 39648.895327
Deduct 3745 from 3800 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 15:
The number 535 fits into 550 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 39648.8953271
Subtracting 535 from 550 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 16:
535 can be fit into 150 0 times, resulting in a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 39648.8953271
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Our division results in 39648.8953271 with a remaining 1.5e-07.
