The number 553 fits into 849 1 times, leaving a remainder of 296.
Write down 1 as next digit of the result. 
Result so far: 21.0
Deduct 553 from 849 and we're left with 296.
Include the next digit (4) from the dividend after 296, then repeat: 2964 / 553

Let's proceed to step 6:
553 goes into 2964 5 times with a remainder of 199.
Use 5 as the next digit of our solution. 
Result so far: 215.0
If we subtract 2765 from 2964, we get 199.
Fetch the next digit (4) from the dividend, attach it to 199 and continue: 1994 / 553

Going ahead to step 7:
If we divide 1994 by 553, we get 3 and a remainder of 335.
Record the quotient 3 as the next digit in the result. 
Result so far: 2153.0
Deduct 1659 from 1994 and we're left with 335.
Fetch the next digit (1) from the dividend, attach it to 335 and continue: 3351 / 553

Going ahead to step 8:
553 goes into 3351 6 times with a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 21536.0
Subtracting 3318 from 3351 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
553 goes into 330 0 times with a remainder of 330.
Use 0 as the next digit of our solution. 
Result so far: 21536.0
If we subtract 0 from 330, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 10:
3300 divided by 553 is 5 with a remainder of 535.
Use 5 as the next digit of our solution. 
Result so far: 21536.05
Subtract 2765 from 3300 to get 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

On to step 11:
If we divide 5350 by 553, we get 9 and a remainder of 373.
The number 9 becomes the next digit in our result. 
Result so far: 21536.059
Deduct 4977 from 5350 and we're left with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Moving on to step 12:
When dividing 3730 by 553, we get 6 with a remainder of 412.
Write down 6 as next digit of the result. 
Result so far: 21536.0596
The remainder is 412 after subtracting 3318 from 3730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Let's proceed to step 13:
553 goes into 4120 7 times with a remainder of 249.
The next digit of our result is 7. 
Result so far: 21536.05967
If we subtract 3871 from 4120, we get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

On to step 14:
2490 divided by 553 is 4 with a remainder of 278.
Write down 4 as next digit of the result. 
Result so far: 21536.059674
Subtract 2212 from 2490 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Let's proceed to step 15:
553 can be fit into 2780 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 21536.0596745
Subtract 2765 from 2780 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 16:
553 goes into 150 0 times with a remainder of 150.
The next digit of our result is 0. 
Result so far: 21536.0596745
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

After the division, we end up with 21536.0596745 and a remainder of 1.5e-07.
