The number 521 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 521

Advancing to step 2:
521 can be fit into 74 0 times, resulting in a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Fetch the next digit (2) from the dividend, attach it to 74 and continue: 742 / 521

Advancing to step 3:
521 can be fit into 742 1 times, resulting in a remainder of 221.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 221 after subtracting 521 from 742.
Take the next digit (5) from the dividend and append it to 221, then repeat: 2215 / 521

Advancing to step 4:
2215 divided by 521 is 4 with a remainder of 131.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 2084 from 2215 to get 131.
Grab the next digit (3) from the dividend, add it to 131, then carry on: 1313 / 521

On to step 5:
The number 521 fits into 1313 2 times, leaving a remainder of 271.
Put 2 as the next digit of the answer. 
Result so far: 142.0
The remainder is 271 after subtracting 1042 from 1313.
Take the next digit (6) from the dividend and append it to 271, then repeat: 2716 / 521

Step 6:
521 can be fit into 2716 5 times, resulting in a remainder of 111.
Write down 5 as next digit of the result. 
Result so far: 1425.0
If we subtract 2605 from 2716, we get 111.
Bring next digit (0) of the dividend behind the 111 and repeat the process: 1110 / 521

Moving on to step 7:
1110 divided by 521 is 2 with a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 14252.0
The remainder is 68 after subtracting 1042 from 1110.
Grab the next digit (0) from the dividend, add it to 68, then carry on: 680 / 521

On to step 8:
680 divided by 521 is 1 with a remainder of 159.
The number 1 becomes the next digit in our result. 
Result so far: 142521.0
Deduct 521 from 680 and we're left with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 9:
When dividing 1590 by 521, we get 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 142521.3
The remainder is 27 after subtracting 1563 from 1590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 10:
521 can be fit into 270 0 times, resulting in a remainder of 270.
Record the quotient 0 as the next digit in the result. 
Result so far: 142521.3
If we take 0 away from 270, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 11:
2700 divided by 521 is 5 with a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 142521.305
Deduct 2605 from 2700 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 12:
950 divided by 521 is 1 with a remainder of 429.
The number 1 becomes the next digit in our result. 
Result so far: 142521.3051
The remainder is 429 after subtracting 521 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Advancing to step 13:
521 can be fit into 4290 8 times, resulting in a remainder of 122.
Put 8 as the next digit of the answer. 
Result so far: 142521.30518
If we take 4168 away from 4290, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 14:
If we divide 1220 by 521, we get 2 and a remainder of 178.
The next digit of our result is 2. 
Result so far: 142521.305182
Subtract 1042 from 1220 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 15:
521 goes into 1780 3 times with a remainder of 217.
Put 3 as the next digit of the answer. 
Result so far: 142521.3051823
Deduct 1563 from 1780 and we're left with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 16:
521 can be fit into 2170 4 times, resulting in a remainder of 86.
Put 4 as the next digit of the answer. 
Result so far: 142521.30518234
If we take 2084 away from 2170, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final result is 142521.30518234 with a remainder of 8.6e-08.
