We're dividing 75663523 by 439 
We want to figure out the number of times 75663523 can be divided by 439.

Going ahead to step 1:
439 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 439

On to step 2:
The number 439 fits into 75 0 times, leaving a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Fetch the next digit (6) from the dividend, attach it to 75 and continue: 756 / 439

Going ahead to step 3:
If we divide 756 by 439, we get 1 and a remainder of 317.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 439 away from 756, we end up with 317.
Append the next digit (6) from the dividend to 317 and continue with: 3176 / 439

Let's proceed to step 4:
439 can be fit into 3176 7 times, resulting in a remainder of 103.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 3073 away from 3176, we end up with 103.
Fetch the next digit (3) from the dividend, attach it to 103 and continue: 1033 / 439

Let's proceed to step 5:
The number 439 fits into 1033 2 times, leaving a remainder of 155.
The next digit of our result is 2. 
Result so far: 172.0
If we subtract 878 from 1033, we get 155.
Include the next digit (5) from the dividend after 155, then repeat: 1555 / 439

Advancing to step 6:
If we divide 1555 by 439, we get 3 and a remainder of 238.
Record the quotient 3 as the next digit in the result. 
Result so far: 1723.0
Subtract 1317 from 1555 to get 238.
Append the next digit (2) from the dividend to 238 and continue with: 2382 / 439

Advancing to step 7:
The number 439 fits into 2382 5 times, leaving a remainder of 187.
Use 5 as the next digit of our solution. 
Result so far: 17235.0
Subtract 2195 from 2382 to get 187.
Fetch the next digit (3) from the dividend, attach it to 187 and continue: 1873 / 439

Moving on to step 8:
439 can be fit into 1873 4 times, resulting in a remainder of 117.
The next digit of our result is 4. 
Result so far: 172354.0
Deduct 1756 from 1873 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Advancing to step 9:
When dividing 1170 by 439, we get 2 with a remainder of 292.
Write down 2 as next digit of the result. 
Result so far: 172354.2
If we subtract 878 from 1170, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 10:
The number 439 fits into 2920 6 times, leaving a remainder of 286.
Write down 6 as next digit of the result. 
Result so far: 172354.26
Subtracting 2634 from 2920 leaves us with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

On to step 11:
2860 divided by 439 is 6 with a remainder of 226.
Use 6 as the next digit of our solution. 
Result so far: 172354.266
Subtract 2634 from 2860 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

The final result is 172354.266 with a remainder of 0.0226.
