Let's divide 21598134 by 849
We're looking to find how many times 849 goes into 21598134.

Moving on to step 1:
849 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 849

Going ahead to step 2:
849 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 849

Advancing to step 3:
849 goes into 215 0 times with a remainder of 215.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 215, we get 215.
Include the next digit (9) from the dividend after 215, then repeat: 2159 / 849

Step 4:
849 can be fit into 2159 2 times, resulting in a remainder of 461.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1698 from 2159 to get 461.
Grab the next digit (8) from the dividend, add it to 461, then carry on: 4618 / 849

On to step 5:
849 can be fit into 4618 5 times, resulting in a remainder of 373.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 4245 away from 4618, we end up with 373.
Append the next digit (1) from the dividend to 373 and continue with: 3731 / 849

Step 6:
If we divide 3731 by 849, we get 4 and a remainder of 335.
The number 4 becomes the next digit in our result. 
Result so far: 254.0
If we subtract 3396 from 3731, we get 335.
Bring next digit (3) of the dividend behind the 335 and repeat the process: 3353 / 849

Going ahead to step 7:
When dividing 3353 by 849, we get 3 with a remainder of 806.
Write down 3 as next digit of the result. 
Result so far: 2543.0
If we subtract 2547 from 3353, we get 806.
Take the next digit (4) from the dividend and append it to 806, then repeat: 8064 / 849

Step 8:
If we divide 8064 by 849, we get 9 and a remainder of 423.
The number 9 becomes the next digit in our result. 
Result so far: 25439.0
Subtracting 7641 from 8064 leaves us with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Let's proceed to step 9:
4230 divided by 849 is 4 with a remainder of 834.
The next digit of our result is 4. 
Result so far: 25439.4
The remainder is 834 after subtracting 3396 from 4230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

Advancing to step 10:
The number 849 fits into 8340 9 times, leaving a remainder of 699.
Put 9 as the next digit of the answer. 
Result so far: 25439.49
If we subtract 7641 from 8340, we get 699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Going ahead to step 11:
If we divide 6990 by 849, we get 8 and a remainder of 198.
The next digit of our result is 8. 
Result so far: 25439.498
Deduct 6792 from 6990 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 12:
When dividing 1980 by 849, we get 2 with a remainder of 282.
Write down 2 as next digit of the result. 
Result so far: 25439.4982
If we subtract 1698 from 1980, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Step 13:
849 goes into 2820 3 times with a remainder of 273.
Record the quotient 3 as the next digit in the result. 
Result so far: 25439.49823
Subtracting 2547 from 2820 leaves us with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Advancing to step 14:
2730 divided by 849 is 3 with a remainder of 183.
Put 3 as the next digit of the answer. 
Result so far: 25439.498233
Subtract 2547 from 2730 to get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

The final outcome is 25439.498233, with a leftover of 1.83e-05.
