When dividing 2077 by 228, we get 9 with a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 2052 from 2077 to get 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 228

Let's proceed to step 5:
257 divided by 228 is 1 with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 191.0
Subtract 228 from 257 to get 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 228

Going ahead to step 6:
If we divide 291 by 228, we get 1 and a remainder of 63.
Put 1 as the next digit of the answer. 
Result so far: 1911.0
The remainder is 63 after subtracting 228 from 291.
Fetch the next digit (3) from the dividend, attach it to 63 and continue: 633 / 228

Moving on to step 7:
228 can be fit into 633 2 times, resulting in a remainder of 177.
Use 2 as the next digit of our solution. 
Result so far: 19112.0
If we take 456 away from 633, we end up with 177.
Fetch the next digit (7) from the dividend, attach it to 177 and continue: 1777 / 228

Advancing to step 8:
When dividing 1777 by 228, we get 7 with a remainder of 181.
Record the quotient 7 as the next digit in the result. 
Result so far: 191127.0
Subtract 1596 from 1777 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 9:
228 goes into 1810 7 times with a remainder of 214.
The next digit of our result is 7. 
Result so far: 191127.7
Subtracting 1596 from 1810 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 10:
228 can be fit into 2140 9 times, resulting in a remainder of 88.
Use 9 as the next digit of our solution. 
Result so far: 191127.79
Subtracting 2052 from 2140 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 11:
880 divided by 228 is 3 with a remainder of 196.
Write down 3 as next digit of the result. 
Result so far: 191127.793
The remainder is 196 after subtracting 684 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 12:
228 goes into 1960 8 times with a remainder of 136.
The next digit of our result is 8. 
Result so far: 191127.7938
If we take 1824 away from 1960, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 13:
228 goes into 1360 5 times with a remainder of 220.
The number 5 becomes the next digit in our result. 
Result so far: 191127.79385
Deduct 1140 from 1360 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 14:
2200 divided by 228 is 9 with a remainder of 148.
Record the quotient 9 as the next digit in the result. 
Result so far: 191127.793859
Deduct 2052 from 2200 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 15:
1480 divided by 228 is 6 with a remainder of 112.
Record the quotient 6 as the next digit in the result. 
Result so far: 191127.7938596
Subtract 1368 from 1480 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.

Moving on to step 16:
228 goes into 1120 4 times with a remainder of 208.
Write down 4 as next digit of the result. 
Result so far: 191127.79385964
Deduct 912 from 1120 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

In conclusion, the division gives 191127.79385964 with a balance of 2.08e-07.
