On to step 5:
When dividing 2905 by 304, we get 9 with a remainder of 169.
Use 9 as the next digit of our solution. 
Result so far: 69.0
Subtract 2736 from 2905 to get 169.
Include the next digit (4) from the dividend after 169, then repeat: 1694 / 304

Let's proceed to step 6:
1694 divided by 304 is 5 with a remainder of 174.
Put 5 as the next digit of the answer. 
Result so far: 695.0
Deduct 1520 from 1694 and we're left with 174.
Grab the next digit (2) from the dividend, add it to 174, then carry on: 1742 / 304

Moving on to step 7:
1742 divided by 304 is 5 with a remainder of 222.
Use 5 as the next digit of our solution. 
Result so far: 6955.0
Subtract 1520 from 1742 to get 222.
Bring next digit (4) of the dividend behind the 222 and repeat the process: 2224 / 304

On to step 8:
When dividing 2224 by 304, we get 7 with a remainder of 96.
Put 7 as the next digit of the answer. 
Result so far: 69557.0
Subtracting 2128 from 2224 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 9:
The number 304 fits into 960 3 times, leaving a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 69557.3
Deduct 912 from 960 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
480 divided by 304 is 1 with a remainder of 176.
The number 1 becomes the next digit in our result. 
Result so far: 69557.31
If we subtract 304 from 480, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 11:
When dividing 1760 by 304, we get 5 with a remainder of 240.
Write down 5 as next digit of the result. 
Result so far: 69557.315
Subtracting 1520 from 1760 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 12:
2400 divided by 304 is 7 with a remainder of 272.
Put 7 as the next digit of the answer. 
Result so far: 69557.3157
Deduct 2128 from 2400 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 13:
304 goes into 2720 8 times with a remainder of 288.
The number 8 becomes the next digit in our result. 
Result so far: 69557.31578
Deduct 2432 from 2720 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 14:
304 goes into 2880 9 times with a remainder of 144.
Write down 9 as next digit of the result. 
Result so far: 69557.315789
Subtracting 2736 from 2880 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 15:
304 goes into 1440 4 times with a remainder of 224.
Put 4 as the next digit of the answer. 
Result so far: 69557.3157894
If we subtract 1216 from 1440, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 16:
When dividing 2240 by 304, we get 7 with a remainder of 112.
Put 7 as the next digit of the answer. 
Result so far: 69557.31578947
Subtract 2128 from 2240 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

In conclusion, the division gives 69557.31578947 with a balance of 1.12e-07.
