66306588 ÷ 534 
Our goal is to divide 66306588 by 534.

On to step 1:
The number 534 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 534

Going ahead to step 2:
The number 534 fits into 66 0 times, leaving a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Grab the next digit (3) from the dividend, add it to 66, then carry on: 663 / 534

Moving on to step 3:
If we divide 663 by 534, we get 1 and a remainder of 129.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 534 from 663 and we're left with 129.
Take the next digit (0) from the dividend and append it to 129, then repeat: 1290 / 534

Step 4:
If we divide 1290 by 534, we get 2 and a remainder of 222.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 1068 from 1290 leaves us with 222.
Append the next digit (6) from the dividend to 222 and continue with: 2226 / 534

Let's proceed to step 5:
The number 534 fits into 2226 4 times, leaving a remainder of 90.
Use 4 as the next digit of our solution. 
Result so far: 124.0
Subtracting 2136 from 2226 leaves us with 90.
Include the next digit (5) from the dividend after 90, then repeat: 905 / 534

Advancing to step 6:
905 divided by 534 is 1 with a remainder of 371.
The number 1 becomes the next digit in our result. 
Result so far: 1241.0
Subtracting 534 from 905 leaves us with 371.
Take the next digit (8) from the dividend and append it to 371, then repeat: 3718 / 534

Advancing to step 7:
534 goes into 3718 6 times with a remainder of 514.
Write down 6 as next digit of the result. 
Result so far: 12416.0
Subtract 3204 from 3718 to get 514.
Fetch the next digit (8) from the dividend, attach it to 514 and continue: 5148 / 534

Going ahead to step 8:
If we divide 5148 by 534, we get 9 and a remainder of 342.
The number 9 becomes the next digit in our result. 
Result so far: 124169.0
If we subtract 4806 from 5148, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Moving on to step 9:
534 goes into 3420 6 times with a remainder of 216.
The number 6 becomes the next digit in our result. 
Result so far: 124169.6
Subtracting 3204 from 3420 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 10:
When dividing 2160 by 534, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 124169.64
Subtracting 2136 from 2160 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.

Going ahead to step 11:
534 can be fit into 240 0 times, resulting in a remainder of 240.
The next digit of our result is 0. 
Result so far: 124169.64
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 12:
534 goes into 2400 4 times with a remainder of 264.
Use 4 as the next digit of our solution. 
Result so far: 124169.6404
If we take 2136 away from 2400, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 13:
When dividing 2640 by 534, we get 4 with a remainder of 504.
Write down 4 as next digit of the result. 
Result so far: 124169.64044
If we take 2136 away from 2640, we end up with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

The final outcome is 124169.64044, with a leftover of 0.000504.
