9 divided by 521 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 521

Let's proceed to step 2:
94 divided by 521 is 0 with a remainder of 94.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 94 after subtracting 0 from 94.
Fetch the next digit (4) from the dividend, attach it to 94 and continue: 944 / 521

Advancing to step 3:
521 can be fit into 944 1 times, resulting in a remainder of 423.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 521 from 944 to get 423.
Grab the next digit (2) from the dividend, add it to 423, then carry on: 4232 / 521

On to step 4:
521 goes into 4232 8 times with a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 4168 from 4232 leaves us with 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 521

Advancing to step 5:
648 divided by 521 is 1 with a remainder of 127.
The number 1 becomes the next digit in our result. 
Result so far: 181.0
The remainder is 127 after subtracting 521 from 648.
Include the next digit (4) from the dividend after 127, then repeat: 1274 / 521

Step 6:
521 can be fit into 1274 2 times, resulting in a remainder of 232.
Write down 2 as next digit of the result. 
Result so far: 1812.0
Deduct 1042 from 1274 and we're left with 232.
Grab the next digit (7) from the dividend, add it to 232, then carry on: 2327 / 521

Moving on to step 7:
If we divide 2327 by 521, we get 4 and a remainder of 243.
The next digit of our result is 4. 
Result so far: 18124.0
The remainder is 243 after subtracting 2084 from 2327.
Include the next digit (8) from the dividend after 243, then repeat: 2438 / 521

Going ahead to step 8:
When dividing 2438 by 521, we get 4 with a remainder of 354.
The number 4 becomes the next digit in our result. 
Result so far: 181244.0
Deduct 2084 from 2438 and we're left with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Advancing to step 9:
521 goes into 3540 6 times with a remainder of 414.
Record the quotient 6 as the next digit in the result. 
Result so far: 181244.6
Subtracting 3126 from 3540 leaves us with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Going ahead to step 10:
The number 521 fits into 4140 7 times, leaving a remainder of 493.
Put 7 as the next digit of the answer. 
Result so far: 181244.67
Deduct 3647 from 4140 and we're left with 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Moving on to step 11:
When dividing 4930 by 521, we get 9 with a remainder of 241.
The next digit of our result is 9. 
Result so far: 181244.679
Subtract 4689 from 4930 to get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

On to step 12:
The number 521 fits into 2410 4 times, leaving a remainder of 326.
Write down 4 as next digit of the result. 
Result so far: 181244.6794
Subtract 2084 from 2410 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Advancing to step 13:
521 can be fit into 3260 6 times, resulting in a remainder of 134.
The number 6 becomes the next digit in our result. 
Result so far: 181244.67946
If we subtract 3126 from 3260, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 14:
1340 divided by 521 is 2 with a remainder of 298.
Record the quotient 2 as the next digit in the result. 
Result so far: 181244.679462
If we subtract 1042 from 1340, we get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Let's proceed to step 15:
521 can be fit into 2980 5 times, resulting in a remainder of 375.
The next digit of our result is 5. 
Result so far: 181244.6794625
Deduct 2605 from 2980 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 16:
If we divide 3750 by 521, we get 7 and a remainder of 103.
Record the quotient 7 as the next digit in the result. 
Result so far: 181244.67946257
Subtract 3647 from 3750 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

After the division, we end up with 181244.67946257 and a remainder of 1.03e-07.
