On to step 2:
15 divided by 849 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 849

Step 3:
When dividing 151 by 849, we get 0 with a remainder of 151.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 151 leaves us with 151.

Subtract 849 from 1512 to get 663.
Bring next digit (6) of the dividend behind the 663 and repeat the process: 6636 / 849

Going ahead to step 5:
When dividing 6636 by 849, we get 7 with a remainder of 693.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 5943 from 6636, we get 693.
Grab the next digit (7) from the dividend, add it to 693, then carry on: 6937 / 849

Going ahead to step 6:
The number 849 fits into 6937 8 times, leaving a remainder of 145.
Record the quotient 8 as the next digit in the result. 
Result so far: 178.0
If we take 6792 away from 6937, we end up with 145.
Grab the next digit (9) from the dividend, add it to 145, then carry on: 1459 / 849

Let's proceed to step 7:
1459 divided by 849 is 1 with a remainder of 610.
The next digit of our result is 1. 
Result so far: 1781.0
Subtract 849 from 1459 to get 610.
Grab the next digit (8) from the dividend, add it to 610, then carry on: 6108 / 849

On to step 8:
When dividing 6108 by 849, we get 7 with a remainder of 165.
The next digit of our result is 7. 
Result so far: 17817.0
Deduct 5943 from 6108 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 9:
The number 849 fits into 1650 1 times, leaving a remainder of 801.
Use 1 as the next digit of our solution. 
Result so far: 17817.1
Deduct 849 from 1650 and we're left with 801.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8010, and continue the process.

On to step 10:
849 goes into 8010 9 times with a remainder of 369.
The number 9 becomes the next digit in our result. 
Result so far: 17817.19
If we take 7641 away from 8010, we end up with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

On to step 11:
3690 divided by 849 is 4 with a remainder of 294.
Put 4 as the next digit of the answer. 
Result so far: 17817.194
Deduct 3396 from 3690 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 12:
If we divide 2940 by 849, we get 3 and a remainder of 393.
Record the quotient 3 as the next digit in the result. 
Result so far: 17817.1943
Subtract 2547 from 2940 to get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

On to step 13:
When dividing 3930 by 849, we get 4 with a remainder of 534.
Put 4 as the next digit of the answer. 
Result so far: 17817.19434
If we take 3396 away from 3930, we end up with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Step 14:
When dividing 5340 by 849, we get 6 with a remainder of 246.
The number 6 becomes the next digit in our result. 
Result so far: 17817.194346
If we take 5094 away from 5340, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 15:
If we divide 2460 by 849, we get 2 and a remainder of 762.
The number 2 becomes the next digit in our result. 
Result so far: 17817.1943462
Subtracting 1698 from 2460 leaves us with 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Advancing to step 16:
849 can be fit into 7620 8 times, resulting in a remainder of 828.
Put 8 as the next digit of the answer. 
Result so far: 17817.19434628
Subtracting 6792 from 7620 leaves us with 828.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8280, and continue the process.

Our division results in 17817.19434628 with a remaining 8.28e-07.
