If we divide 1 by 849, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 849

Going ahead to step 2:
19 divided by 849 is 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 849

Advancing to step 3:
When dividing 199 by 849, we get 0 with a remainder of 199.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 199 and we're left with 199.
Append the next digit (0) from the dividend to 199 and continue with: 1990 / 849

On to step 4:
849 can be fit into 1990 2 times, resulting in a remainder of 292.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1698 from 1990 and we're left with 292.
Grab the next digit (7) from the dividend, add it to 292, then carry on: 2927 / 849

Let's proceed to step 5:
2927 divided by 849 is 3 with a remainder of 380.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we take 2547 away from 2927, we end up with 380.
Append the next digit (4) from the dividend to 380 and continue with: 3804 / 849

Step 6:
3804 divided by 849 is 4 with a remainder of 408.
Put 4 as the next digit of the answer. 
Result so far: 234.0
Subtracting 3396 from 3804 leaves us with 408.
Fetch the next digit (5) from the dividend, attach it to 408 and continue: 4085 / 849

Going ahead to step 7:
The number 849 fits into 4085 4 times, leaving a remainder of 689.
Put 4 as the next digit of the answer. 
Result so far: 2344.0
Subtracting 3396 from 4085 leaves us with 689.
Fetch the next digit (7) from the dividend, attach it to 689 and continue: 6897 / 849

Going ahead to step 8:
The number 849 fits into 6897 8 times, leaving a remainder of 105.
Write down 8 as next digit of the result. 
Result so far: 23448.0
Deduct 6792 from 6897 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 9:
If we divide 1050 by 849, we get 1 and a remainder of 201.
The number 1 becomes the next digit in our result. 
Result so far: 23448.1
If we take 849 away from 1050, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Advancing to step 10:
849 goes into 2010 2 times with a remainder of 312.
The number 2 becomes the next digit in our result. 
Result so far: 23448.12
Subtract 1698 from 2010 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 11:
849 goes into 3120 3 times with a remainder of 573.
Write down 3 as next digit of the result. 
Result so far: 23448.123
If we subtract 2547 from 3120, we get 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Let's proceed to step 12:
When dividing 5730 by 849, we get 6 with a remainder of 636.
The next digit of our result is 6. 
Result so far: 23448.1236
Subtracting 5094 from 5730 leaves us with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Advancing to step 13:
The number 849 fits into 6360 7 times, leaving a remainder of 417.
The next digit of our result is 7. 
Result so far: 23448.12367
The remainder is 417 after subtracting 5943 from 6360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Moving on to step 14:
If we divide 4170 by 849, we get 4 and a remainder of 774.
The next digit of our result is 4. 
Result so far: 23448.123674
Subtract 3396 from 4170 to get 774.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

Step 15:
849 goes into 7740 9 times with a remainder of 99.
Use 9 as the next digit of our solution. 
Result so far: 23448.1236749
If we subtract 7641 from 7740, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 16:
849 can be fit into 990 1 times, resulting in a remainder of 141.
Write down 1 as next digit of the result. 
Result so far: 23448.12367491
Deduct 849 from 990 and we're left 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.

The final result is 23448.12367491 with a remainder of 1.41e-07.
