Step 1:
6 divided by 231 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 231

Advancing to step 2:
If we divide 60 by 231, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 60 and we're left with 60.
Fetch the next digit (9) from the dividend, attach it to 60 and continue: 609 / 231

On to step 4:
When dividing 1477 by 231, we get 6 with a remainder of 91.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we take 1386 away from 1477, we end up with 91.
Fetch the next digit (5) from the dividend, attach it to 91 and continue: 915 / 231

Let's proceed to step 5:
231 goes into 915 3 times with a remainder of 222.
The number 3 becomes the next digit in our result. 
Result so far: 263.0
If we subtract 693 from 915, we get 222.
Append the next digit (9) from the dividend to 222 and continue with: 2229 / 231

Advancing to step 6:
When dividing 2229 by 231, we get 9 with a remainder of 150.
The number 9 becomes the next digit in our result. 
Result so far: 2639.0
Subtracting 2079 from 2229 leaves us with 150.
Bring next digit (0) of the dividend behind the 150 and repeat the process: 1500 / 231

Going ahead to step 7:
1500 divided by 231 is 6 with a remainder of 114.
The number 6 becomes the next digit in our result. 
Result so far: 26396.0
Subtracting 1386 from 1500 leaves us with 114.
Grab the next digit (6) from the dividend, add it to 114, then carry on: 1146 / 231

Let's proceed to step 8:
1146 divided by 231 is 4 with a remainder of 222.
Use 4 as the next digit of our solution. 
Result so far: 263964.0
Deduct 924 from 1146 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Moving on to step 9:
231 can be fit into 2220 9 times, resulting in a remainder of 141.
Use 9 as the next digit of our solution. 
Result so far: 263964.9
If we take 2079 away from 2220, we end up with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Let's proceed to step 10:
The number 231 fits into 1410 6 times, leaving a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 263964.96
The remainder is 24 after subtracting 1386 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
The number 231 fits into 240 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 263964.961
The remainder is 9 after subtracting 231 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 12:
The number 231 fits into 90 0 times, leaving a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 263964.961
Subtract 0 from 90 to get 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 13:
If we divide 900 by 231, we get 3 and a remainder of 207.
Write down 3 as next digit of the result. 
Result so far: 263964.96103
Subtract 693 from 900 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Let's proceed to step 14:
231 goes into 2070 8 times with a remainder of 222.
The next digit of our result is 8. 
Result so far: 263964.961038
Deduct 1848 from 2070 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 15:
2220 divided by 231 is 9 with a remainder of 141.
Use 9 as the next digit of our solution. 
Result so far: 263964.9610389
The remainder is 141 after subtracting 2079 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 16:
If we divide 1410 by 231, we get 6 and a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 263964.96103896
Deduct 1386 from 1410 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 263964.96103896 with a balance of 2.4e-08.
