When dividing 4 by 199, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 199

On to step 2:
43 divided by 199 is 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Bring next digit (3) of the dividend behind the 43 and repeat the process: 433 / 199

Moving on to step 3:
The number 199 fits into 433 2 times, leaving a remainder of 35.
The number 2 becomes the next digit in our result. 
Result so far: 2.0

Append the next digit (9) from the dividend to 35 and continue with: 359 / 199

Going ahead to step 4:
The number 199 fits into 359 1 times, leaving a remainder of 160.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 199 from 359, we get 160.
Grab the next digit (2) from the dividend, add it to 160, then carry on: 1602 / 199

On to step 5:
When dividing 1602 by 199, we get 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 218.0
If we subtract 1592 from 1602, we get 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 199

Let's proceed to step 6:
If we divide 105 by 199, we get 0 and a remainder of 105.
Record the quotient 0 as the next digit in the result. 
Result so far: 2180.0
The remainder is 105 after subtracting 0 from 105.
Append the next digit (0) from the dividend to 105 and continue with: 1050 / 199

Moving on to step 7:
199 goes into 1050 5 times with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 21805.0
If we subtract 995 from 1050, we get 55.
Take the next digit (6) from the dividend and append it to 55, then repeat: 556 / 199

Advancing to step 8:
199 can be fit into 556 2 times, resulting in a remainder of 158.
The number 2 becomes the next digit in our result. 
Result so far: 218052.0
If we subtract 398 from 556, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 9:
The number 199 fits into 1580 7 times, leaving a remainder of 187.
Record the quotient 7 as the next digit in the result. 
Result so far: 218052.7
The remainder is 187 after subtracting 1393 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Moving on to step 10:
If we divide 1870 by 199, we get 9 and a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 218052.79
Deduct 1791 from 1870 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 11:
790 divided by 199 is 3 with a remainder of 193.
Use 3 as the next digit of our solution. 
Result so far: 218052.793
Subtract 597 from 790 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Step 12:
199 can be fit into 1930 9 times, resulting in a remainder of 139.
The number 9 becomes the next digit in our result. 
Result so far: 218052.7939
The remainder is 139 after subtracting 1791 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Going ahead to step 13:
199 can be fit into 1390 6 times, resulting in a remainder of 196.
Use 6 as the next digit of our solution. 
Result so far: 218052.79396
If we subtract 1194 from 1390, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 14:
199 goes into 1960 9 times with a remainder of 169.
Record the quotient 9 as the next digit in the result. 
Result so far: 218052.793969
The remainder is 169 after subtracting 1791 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Let's proceed to step 15:
The number 199 fits into 1690 8 times, leaving a remainder of 98.
The number 8 becomes the next digit in our result. 
Result so far: 218052.7939698
The remainder is 98 after subtracting 1592 from 1690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 16:
199 can be fit into 980 4 times, resulting in a remainder of 184.
The next digit of our result is 4. 
Result so far: 218052.79396984
If we subtract 796 from 980, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The final outcome is 218052.79396984, with a leftover of 1.84e-07.
