Let's divide 21413435 by 824
We want to figure out the number of times 21413435 can be divided by 824.

Advancing to step 1:
The number 824 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
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 / 824

Step 2:
824 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 824

On to step 3:
The number 824 fits into 214 0 times, leaving a remainder of 214.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 214, we end up with 214.
Bring next digit (1) of the dividend behind the 214 and repeat the process: 2141 / 824

On to step 4:
824 can be fit into 2141 2 times, resulting in a remainder of 493.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1648 from 2141 to get 493.
Grab the next digit (3) from the dividend, add it to 493, then carry on: 4933 / 824

On to step 5:
4933 divided by 824 is 5 with a remainder of 813.
The next digit of our result is 5. 
Result so far: 25.0
If we subtract 4120 from 4933, we get 813.
Append the next digit (4) from the dividend to 813 and continue with: 8134 / 824

Let's proceed to step 6:
824 can be fit into 8134 9 times, resulting in a remainder of 718.
The next digit of our result is 9. 
Result so far: 259.0
If we take 7416 away from 8134, we end up with 718.
Grab the next digit (3) from the dividend, add it to 718, then carry on: 7183 / 824

Advancing to step 7:
824 can be fit into 7183 8 times, resulting in a remainder of 591.
Put 8 as the next digit of the answer. 
Result so far: 2598.0
Deduct 6592 from 7183 and we're left with 591.
Fetch the next digit (5) from the dividend, attach it to 591 and continue: 5915 / 824

Moving on to step 8:
824 goes into 5915 7 times with a remainder of 147.
Put 7 as the next digit of the answer. 
Result so far: 25987.0
Deduct 5768 from 5915 and we're left with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Step 9:
824 goes into 1470 1 times with a remainder of 646.
The next digit of our result is 1. 
Result so far: 25987.1
Subtracting 824 from 1470 leaves us with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Going ahead to step 10:
When dividing 6460 by 824, we get 7 with a remainder of 692.
Record the quotient 7 as the next digit in the result. 
Result so far: 25987.17
The remainder is 692 after subtracting 5768 from 6460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Step 11:
824 goes into 6920 8 times with a remainder of 328.
The next digit of our result is 8. 
Result so far: 25987.178
Subtract 6592 from 6920 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 12:
The number 824 fits into 3280 3 times, leaving a remainder of 808.
The number 3 becomes the next digit in our result. 
Result so far: 25987.1783
Subtract 2472 from 3280 to get 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

Step 13:
824 can be fit into 8080 9 times, resulting in a remainder of 664.
Record the quotient 9 as the next digit in the result. 
Result so far: 25987.17839
If we take 7416 away from 8080, we end up with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

On to step 14:
824 goes into 6640 8 times with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 25987.178398
The remainder is 48 after subtracting 6592 from 6640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 15:
824 goes into 480 0 times with a remainder of 480.
The next digit of our result is 0. 
Result so far: 25987.178398
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 16:
824 can be fit into 4800 5 times, resulting in a remainder of 680.
Record the quotient 5 as the next digit in the result. 
Result so far: 25987.17839805
If we subtract 4120 from 4800, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Our division results in 25987.17839805 with a remaining 6.8e-07.
