3179 divided by 594 is 5 with a remainder of 209.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
Subtract 2970 from 3179 to get 209.
Grab the next digit (5) from the dividend, add it to 209, then carry on: 2095 / 594

Going ahead to step 6:
If we divide 2095 by 594, we get 3 and a remainder of 313.
Record the quotient 3 as the next digit in the result. 
Result so far: 1353.0
If we subtract 1782 from 2095, we get 313.
Take the next digit (5) from the dividend and append it to 313, then repeat: 3135 / 594

Advancing to step 7:
594 can be fit into 3135 5 times, resulting in a remainder of 165.
Put 5 as the next digit of the answer. 
Result so far: 13535.0
The remainder is 165 after subtracting 2970 from 3135.
Grab the next digit (9) from the dividend, add it to 165, then carry on: 1659 / 594

Moving on to step 8:
If we divide 1659 by 594, we get 2 and a remainder of 471.
Record the quotient 2 as the next digit in the result. 
Result so far: 135352.0
If we take 1188 away from 1659, we end up with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Moving on to step 9:
The number 594 fits into 4710 7 times, leaving a remainder of 552.
The next digit of our result is 7. 
Result so far: 135352.7
Subtract 4158 from 4710 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 10:
594 goes into 5520 9 times with a remainder of 174.
The number 9 becomes the next digit in our result. 
Result so far: 135352.79
Subtract 5346 from 5520 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 11:
When dividing 1740 by 594, we get 2 with a remainder of 552.
Record the quotient 2 as the next digit in the result. 
Result so far: 135352.792
The remainder is 552 after subtracting 1188 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Step 12:
The number 594 fits into 5520 9 times, leaving a remainder of 174.
Put 9 as the next digit of the answer. 
Result so far: 135352.7929
Subtracting 5346 from 5520 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 13:
594 can be fit into 1740 2 times, resulting in a remainder of 552.
The number 2 becomes the next digit in our result. 
Result so far: 135352.79292
If we subtract 1188 from 1740, we get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Moving on to step 14:
The number 594 fits into 5520 9 times, leaving a remainder of 174.
Write down 9 as next digit of the result. 
Result so far: 135352.792929
Subtracting 5346 from 5520 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 15:
If we divide 1740 by 594, we get 2 and a remainder of 552.
Use 2 as the next digit of our solution. 
Result so far: 135352.7929292
Deduct 1188 from 1740 and we're left with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Let's proceed to step 16:
When dividing 5520 by 594, we get 9 with a remainder of 174.
Write down 9 as next digit of the result. 
Result so far: 135352.79292929
