Let's divide 21509138 by 182
Our goal is to divide 21509138 by 182.

On to step 1:
When dividing 2 by 182, we get 0 with 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 / 182

Going ahead to step 2:
21 divided by 182 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 182

Moving on to step 3:
If we divide 215 by 182, we get 1 and a remainder of 33.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 33 after subtracting 182 from 215.
Include the next digit (0) from the dividend after 33, then repeat: 330 / 182

Step 4:
182 can be fit into 330 1 times, resulting in a remainder of 148.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 182 from 330 and we're left with 148.
Grab the next digit (9) from the dividend, add it to 148, then carry on: 1489 / 182

Let's proceed to step 5:
1489 divided by 182 is 8 with a remainder of 33.
Write down 8 as next digit of the result. 
Result so far: 118.0
Subtract 1456 from 1489 to get 33.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 182

Let's proceed to step 6:
If we divide 331 by 182, we get 1 and a remainder of 149.
The number 1 becomes the next digit in our result. 
Result so far: 1181.0
If we take 182 away from 331, we end up with 149.
Grab the next digit (3) from the dividend, add it to 149, then carry on: 1493 / 182

Let's proceed to step 7:
182 can be fit into 1493 8 times, resulting in a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 11818.0
Subtracting 1456 from 1493 leaves us with 37.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 182

On to step 8:
If we divide 378 by 182, we get 2 and a remainder of 14.
The next digit of our result is 2. 
Result so far: 118182.0
Deduct 364 from 378 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
182 can be fit into 140 0 times, resulting in a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 118182.0
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
182 can be fit into 1400 7 times, resulting in a remainder of 126.
The next digit of our result is 7. 
Result so far: 118182.07
Subtracting 1274 from 1400 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 11:
If we divide 1260 by 182, we get 6 and a remainder of 168.
The number 6 becomes the next digit in our result. 
Result so far: 118182.076
If we take 1092 away from 1260, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 12:
When dividing 1680 by 182, we get 9 with a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 118182.0769
If we subtract 1638 from 1680, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
420 divided by 182 is 2 with a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 118182.07692
Subtracting 364 from 420 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 14:
If we divide 560 by 182, we get 3 and a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 118182.076923
Subtracting 546 from 560 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 15:
182 can be fit into 140 0 times, resulting in a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 118182.076923
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 16:
When dividing 1400 by 182, we get 7 with a remainder of 126.
Record the quotient 7 as the next digit in the result. 
Result so far: 118182.07692307
Subtracting 1274 from 1400 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

The final result is 118182.07692307 with a remainder of 1.26e-07.
