We're dividing 6645144 by 534 
Let's see how many times 534 fits into 6645144.

Going ahead to step 1:
534 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 534

Advancing to step 2:
When dividing 66 by 534, we get 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 534

Step 3:
664 divided by 534 is 1 with a remainder of 130.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 130 after subtracting 534 from 664.
Append the next digit (5) from the dividend to 130 and continue with: 1305 / 534

Advancing to step 4:
534 can be fit into 1305 2 times, resulting in a remainder of 237.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 1068 from 1305, we get 237.
Append the next digit (1) from the dividend to 237 and continue with: 2371 / 534

Going ahead to step 5:
The number 534 fits into 2371 4 times, leaving a remainder of 235.
The next digit of our result is 4. 
Result so far: 124.0
If we take 2136 away from 2371, we end up with 235.
Grab the next digit (4) from the dividend, add it to 235, then carry on: 2354 / 534

Moving on to step 6:
If we divide 2354 by 534, we get 4 and a remainder of 218.
Record the quotient 4 as the next digit in the result. 
Result so far: 1244.0
Subtracting 2136 from 2354 leaves us with 218.
Include the next digit (4) from the dividend after 218, then repeat: 2184 / 534

On to step 7:
534 goes into 2184 4 times with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 12444.0
If we take 2136 away from 2184, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 8:
534 can be fit into 480 0 times, resulting in a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 12444.0
If we subtract 0 from 480, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 9:
When dividing 4800 by 534, we get 8 with a remainder of 528.
Put 8 as the next digit of the answer. 
Result so far: 12444.08
Subtract 4272 from 4800 to get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Step 10:
534 can be fit into 5280 9 times, resulting in a remainder of 474.
The next digit of our result is 9. 
Result so far: 12444.089
If we subtract 4806 from 5280, we get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

On to step 11:
534 can be fit into 4740 8 times, resulting in a remainder of 468.
Put 8 as the next digit of the answer. 
Result so far: 12444.0898
The remainder is 468 after subtracting 4272 from 4740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Let's proceed to step 12:
534 can be fit into 4680 8 times, resulting in a remainder of 408.
Use 8 as the next digit of our solution. 
Result so far: 12444.08988
Subtracting 4272 from 4680 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Our division results in 12444.08988 with a remaining 0.000408.
