We look at the division of 18333221 by 507 
Let's see how many times 507 fits into 18333221.

Going ahead to step 1:
507 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 507

On to step 2:
507 can be fit into 18 0 times, resulting in a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 507

Advancing to step 3:
When dividing 183 by 507, we get 0 with a remainder of 183.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 183 leaves us with 183.
Include the next digit (3) from the dividend after 183, then repeat: 1833 / 507

Advancing to step 4:
507 can be fit into 1833 3 times, resulting in a remainder of 312.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 312 after subtracting 1521 from 1833.
Take the next digit (3) from the dividend and append it to 312, then repeat: 3123 / 507

Going ahead to step 5:
3123 divided by 507 is 6 with a remainder of 81.
Put 6 as the next digit of the answer. 
Result so far: 36.0
If we take 3042 away from 3123, we end up with 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 507

Let's proceed to step 6:
507 goes into 812 1 times with a remainder of 305.
The next digit of our result is 1. 
Result so far: 361.0
Deduct 507 from 812 and we're left with 305.
Fetch the next digit (2) from the dividend, attach it to 305 and continue: 3052 / 507

Step 7:
If we divide 3052 by 507, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 3616.0
The remainder is 10 after subtracting 3042 from 3052.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 507

On to step 8:
The number 507 fits into 101 0 times, leaving a remainder of 101.
Record the quotient 0 as the next digit in the result. 
Result so far: 36160.0
If we subtract 0 from 101, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 9:
The number 507 fits into 1010 1 times, leaving a remainder of 503.
Record the quotient 1 as the next digit in the result. 
Result so far: 36160.1
If we take 507 away from 1010, we end up with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Let's proceed to step 10:
507 goes into 5030 9 times with a remainder of 467.
Write down 9 as next digit of the result. 
Result so far: 36160.19
If we take 4563 away from 5030, we end up with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Moving on to step 11:
507 can be fit into 4670 9 times, resulting in a remainder of 107.
Write down 9 as next digit of the result. 
Result so far: 36160.199
Subtracting 4563 from 4670 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

After the division, we end up with 36160.199 and a remainder of 0.0107.
