Advancing to step 3:
When dividing 257 by 590, we get 0 with a remainder of 257.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 257 to get 257.
Fetch the next digit (7) from the dividend, attach it to 257 and continue: 2577 / 590

Going ahead to step 4:
The number 590 fits into 2577 4 times, leaving a remainder of 217.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 217 after subtracting 2360 from 2577.
Take the next digit (8) from the dividend and append it to 217, then repeat: 2178 / 590

Going ahead to step 5:
When dividing 2178 by 590, we get 3 with a remainder of 408.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Deduct 1770 from 2178 and we're left with 408.
Append the next digit (9) from the dividend to 408 and continue with: 4089 / 590

Going ahead to step 6:
The number 590 fits into 4089 6 times, leaving a remainder of 549.
The next digit of our result is 6. 
Result so far: 436.0
If we take 3540 away from 4089, we end up with 549.
Bring next digit (8) of the dividend behind the 549 and repeat the process: 5498 / 590

Advancing to step 7:
The number 590 fits into 5498 9 times, leaving a remainder of 188.
Put 9 as the next digit of the answer. 
Result so far: 4369.0
Subtract 5310 from 5498 to get 188.
Append the next digit (9) from the dividend to 188 and continue with: 1889 / 590

Advancing to step 8:
When dividing 1889 by 590, we get 3 with a remainder of 119.
The next digit of our result is 3. 
Result so far: 43693.0
Subtracting 1770 from 1889 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Going ahead to step 9:
590 goes into 1190 2 times with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 43693.2
If we take 1180 away from 1190, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
100 divided by 590 is 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 43693.2
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
590 can be fit into 1000 1 times, resulting in a remainder of 410.
The next digit of our result is 1. 
Result so far: 43693.201
If we take 590 away from 1000, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 12:
590 can be fit into 4100 6 times, resulting in a remainder of 560.
The number 6 becomes the next digit in our result. 
Result so far: 43693.2016
If we take 3540 away from 4100, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 13:
590 goes into 5600 9 times with a remainder of 290.
Use 9 as the next digit of our solution. 
Result so far: 43693.20169
If we take 5310 away from 5600, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 14:
When dividing 2900 by 590, we get 4 with a remainder of 540.
Record the quotient 4 as the next digit in the result. 
Result so far: 43693.201694
Subtracting 2360 from 2900 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 15:
590 can be fit into 5400 9 times, resulting in a remainder of 90.
Record the quotient 9 as the next digit in the result. 
Result so far: 43693.2016949
Deduct 5310 from 5400 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 16:
590 goes into 900 1 times with a remainder of 310.
Put 1 as the next digit of the answer. 
Result so far: 43693.20169491
Subtract 590 from 900 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

After the division, we end up with 43693.20169491 and a remainder of 3.1e-07.
