6604386 ÷ 524 
Our goal is to divide 6604386 by 524.

Advancing to step 1:
524 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 524

Going ahead to step 2:
66 divided by 524 is 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Bring next digit (0) of the dividend behind the 66 and repeat the process: 660 / 524

Let's proceed to step 3:
524 goes into 660 1 times with a remainder of 136.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 524 away from 660, we end up with 136.
Grab the next digit (4) from the dividend, add it to 136, then carry on: 1364 / 524

Moving on to step 4:
524 goes into 1364 2 times with a remainder of 316.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 1048 from 1364 and we're left with 316.
Bring next digit (3) of the dividend behind the 316 and repeat the process: 3163 / 524

Going ahead to step 5:
When dividing 3163 by 524, we get 6 with a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
Subtracting 3144 from 3163 leaves us with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 524

On to step 6:
198 divided by 524 is 0 with a remainder of 198.
Put 0 as the next digit of the answer. 
Result so far: 1260.0
Subtract 0 from 198 to get 198.
Bring next digit (6) of the dividend behind the 198 and repeat the process: 1986 / 524

On to step 7:
1986 divided by 524 is 3 with a remainder of 414.
The number 3 becomes the next digit in our result. 
Result so far: 12603.0
If we subtract 1572 from 1986, we get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Let's proceed to step 8:
524 can be fit into 4140 7 times, resulting in a remainder of 472.
Record the quotient 7 as the next digit in the result. 
Result so far: 12603.7
Subtract 3668 from 4140 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

On to step 9:
The number 524 fits into 4720 9 times, leaving a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 12603.79
If we subtract 4716 from 4720, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
40 divided by 524 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 12603.79
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
The number 524 fits into 400 0 times, leaving a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 12603.79
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Our division results in 12603.79 with a remaining 0.004.
