We look at the division of 88180020 by 523 
We want to figure out the number of times 88180020 can be divided by 523.

Step 1:
When dividing 8 by 523, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 523

Advancing to step 2:
523 goes into 88 0 times with a remainder of 88.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Append the next digit (1) from the dividend to 88 and continue with: 881 / 523

Going ahead to step 3:
523 can be fit into 881 1 times, resulting in a remainder of 358.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 358 after subtracting 523 from 881.
Bring next digit (8) of the dividend behind the 358 and repeat the process: 3588 / 523

Step 4:
If we divide 3588 by 523, we get 6 and a remainder of 450.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 3138 from 3588 leaves us with 450.
Fetch the next digit (0) from the dividend, attach it to 450 and continue: 4500 / 523

Moving on to step 5:
4500 divided by 523 is 8 with a remainder of 316.
Write down 8 as next digit of the result. 
Result so far: 168.0
If we take 4184 away from 4500, we end up with 316.
Bring next digit (0) of the dividend behind the 316 and repeat the process: 3160 / 523

Advancing to step 6:
When dividing 3160 by 523, we get 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 1686.0
Subtract 3138 from 3160 to get 22.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 523

Let's proceed to step 7:
523 goes into 222 0 times with a remainder of 222.
Record the quotient 0 as the next digit in the result. 
Result so far: 16860.0
Subtracting 0 from 222 leaves us with 222.
Append the next digit (0) from the dividend to 222 and continue with: 2220 / 523

Let's proceed to step 8:
2220 divided by 523 is 4 with a remainder of 128.
Put 4 as the next digit of the answer. 
Result so far: 168604.0
The remainder is 128 after subtracting 2092 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 9:
523 can be fit into 1280 2 times, resulting in a remainder of 234.
Write down 2 as next digit of the result. 
Result so far: 168604.2
If we subtract 1046 from 1280, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Step 10:
523 can be fit into 2340 4 times, resulting in a remainder of 248.
Put 4 as the next digit of the answer. 
Result so far: 168604.24
If we take 2092 away from 2340, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 11:
2480 divided by 523 is 4 with a remainder of 388.
The next digit of our result is 4. 
Result so far: 168604.244
Deduct 2092 from 2480 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Our division results in 168604.244 with a remaining 0.0388.
