We're dividing 19645438 by 553 
Let's see how many times 553 fits into 19645438.

Going ahead to step 1:
1 divided by 553 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 553

Moving on to step 2:
553 can be fit into 19 0 times, resulting in a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 553

Going ahead to step 3:
196 divided by 553 is 0 with a remainder of 196.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 196, we end up with 196.
Fetch the next digit (4) from the dividend, attach it to 196 and continue: 1964 / 553

On to step 4:
553 can be fit into 1964 3 times, resulting in a remainder of 305.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 1659 from 1964, we get 305.
Include the next digit (5) from the dividend after 305, then repeat: 3055 / 553

Moving on to step 5:
If we divide 3055 by 553, we get 5 and a remainder of 290.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we take 2765 away from 3055, we end up with 290.
Take the next digit (4) from the dividend and append it to 290, then repeat: 2904 / 553

Moving on to step 6:
553 goes into 2904 5 times with a remainder of 139.
Use 5 as the next digit of our solution. 
Result so far: 355.0
If we take 2765 away from 2904, we end up with 139.
Bring next digit (3) of the dividend behind the 139 and repeat the process: 1393 / 553

Advancing to step 7:
When dividing 1393 by 553, we get 2 with a remainder of 287.
Put 2 as the next digit of the answer. 
Result so far: 3552.0
Deduct 1106 from 1393 and we're left with 287.
Include the next digit (8) from the dividend after 287, then repeat: 2878 / 553

Going ahead to step 8:
553 goes into 2878 5 times with a remainder of 113.
The next digit of our result is 5. 
Result so far: 35525.0
The remainder is 113 after subtracting 2765 from 2878.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Let's proceed to step 9:
1130 divided by 553 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 35525.2
Subtracting 1106 from 1130 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
240 divided by 553 is 0 with a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 35525.2
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 11:
The number 553 fits into 2400 4 times, leaving a remainder of 188.
The number 4 becomes the next digit in our result. 
Result so far: 35525.204
Subtracting 2212 from 2400 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 12:
1880 divided by 553 is 3 with a remainder of 221.
Use 3 as the next digit of our solution. 
Result so far: 35525.2043
Subtracting 1659 from 1880 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

On to step 13:
If we divide 2210 by 553, we get 3 and a remainder of 551.
The number 3 becomes the next digit in our result. 
Result so far: 35525.20433
If we subtract 1659 from 2210, we get 551.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

The final outcome is 35525.20433, with a leftover of 0.000551.
