Subtract 0 from 3 to get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 523

Let's proceed to step 2:
When dividing 37 by 523, we get 0 with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Include the next digit (6) from the dividend after 37, then repeat: 376 / 523

On to step 3:
523 can be fit into 376 0 times, resulting in a remainder of 376.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 376 after subtracting 0 from 376.
Bring next digit (1) of the dividend behind the 376 and repeat the process: 3761 / 523

Moving on to step 4:
The number 523 fits into 3761 7 times, leaving a remainder of 100.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 3661 from 3761 to get 100.
Bring next digit (8) of the dividend behind the 100 and repeat the process: 1008 / 523

Let's proceed to step 5:
523 can be fit into 1008 1 times, resulting in a remainder of 485.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Subtracting 523 from 1008 leaves us with 485.
Fetch the next digit (1) from the dividend, attach it to 485 and continue: 4851 / 523

Let's proceed to step 6:
523 can be fit into 4851 9 times, resulting in a remainder of 144.
Use 9 as the next digit of our solution. 
Result so far: 719.0
If we subtract 4707 from 4851, we get 144.
Grab the next digit (4) from the dividend, add it to 144, then carry on: 1444 / 523

Advancing to step 7:
523 can be fit into 1444 2 times, resulting in a remainder of 398.
The next digit of our result is 2. 
Result so far: 7192.0
Subtract 1046 from 1444 to get 398.
Append the next digit (5) from the dividend to 398 and continue with: 3985 / 523

Step 8:
When dividing 3985 by 523, we get 7 with a remainder of 324.
Put 7 as the next digit of the answer. 
Result so far: 71927.0
Subtract 3661 from 3985 to get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

On to step 9:
523 can be fit into 3240 6 times, resulting in a remainder of 102.
Put 6 as the next digit of the answer. 
Result so far: 71927.6
If we take 3138 away from 3240, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 10:
1020 divided by 523 is 1 with a remainder of 497.
Record the quotient 1 as the next digit in the result. 
Result so far: 71927.61
The remainder is 497 after subtracting 523 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

On to step 11:
The number 523 fits into 4970 9 times, leaving a remainder of 263.
The next digit of our result is 9. 
Result so far: 71927.619
If we take 4707 away from 4970, we end up with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Let's proceed to step 12:
2630 divided by 523 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 71927.6195
The remainder is 15 after subtracting 2615 from 2630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 13:
523 can be fit into 150 0 times, resulting in a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 71927.6195
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 14:
The number 523 fits into 1500 2 times, leaving a remainder of 454.
Use 2 as the next digit of our solution. 
Result so far: 71927.619502
Subtract 1046 from 1500 to get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

On to step 15:
When dividing 4540 by 523, we get 8 with a remainder of 356.
Put 8 as the next digit of the answer. 
Result so far: 71927.6195028
The remainder is 356 after subtracting 4184 from 4540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 16:
If we divide 3560 by 523, we get 6 and a remainder of 422.
The next digit of our result is 6. 
Result so far: 71927.61950286
If we subtract 3138 from 3560, we get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

The final result is 71927.61950286 with a remainder of 4.22e-07.
