42539366 divided by 492 
Our goal is to divide 42539366 by 492.

On to step 1:
When dividing 4 by 492, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 492

Moving on to step 2:
When dividing 42 by 492, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 492

Going ahead to step 3:
When dividing 425 by 492, we get 0 with a remainder of 425.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 425, we end up with 425.
Fetch the next digit (3) from the dividend, attach it to 425 and continue: 4253 / 492

Step 4:
If we divide 4253 by 492, we get 8 and a remainder of 317.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 3936 from 4253 leaves us with 317.
Take the next digit (9) from the dividend and append it to 317, then repeat: 3179 / 492

On to step 5:
The number 492 fits into 3179 6 times, leaving a remainder of 227.
Put 6 as the next digit of the answer. 
Result so far: 86.0
Subtracting 2952 from 3179 leaves us with 227.
Grab the next digit (3) from the dividend, add it to 227, then carry on: 2273 / 492

On to step 6:
If we divide 2273 by 492, we get 4 and a remainder of 305.
The number 4 becomes the next digit in our result. 
Result so far: 864.0
Subtracting 1968 from 2273 leaves us with 305.
Grab the next digit (6) from the dividend, add it to 305, then carry on: 3056 / 492

Going ahead to step 7:
492 goes into 3056 6 times with a remainder of 104.
Use 6 as the next digit of our solution. 
Result so far: 8646.0
Subtracting 2952 from 3056 leaves us with 104.
Grab the next digit (6) from the dividend, add it to 104, then carry on: 1046 / 492

Going ahead to step 8:
492 can be fit into 1046 2 times, resulting in a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 86462.0
If we subtract 984 from 1046, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 9:
492 goes into 620 1 times with a remainder of 128.
The number 1 becomes the next digit in our result. 
Result so far: 86462.1
Deduct 492 from 620 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 10:
The number 492 fits into 1280 2 times, leaving a remainder of 296.
Record the quotient 2 as the next digit in the result. 
Result so far: 86462.12
If we take 984 away from 1280, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 11:
2960 divided by 492 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 86462.126
If we take 2952 away from 2960, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
If we divide 80 by 492, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 86462.126
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
492 goes into 800 1 times with a remainder of 308.
Record the quotient 1 as the next digit in the result. 
Result so far: 86462.12601
The remainder is 308 after subtracting 492 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 14:
When dividing 3080 by 492, we get 6 with a remainder of 128.
Put 6 as the next digit of the answer. 
Result so far: 86462.126016
The remainder is 128 after subtracting 2952 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 15:
When dividing 1280 by 492, we get 2 with a remainder of 296.
Record the quotient 2 as the next digit in the result. 
Result so far: 86462.1260162
The remainder is 296 after subtracting 984 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 16:
When dividing 2960 by 492, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 86462.12601626
Subtracting 2952 from 2960 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 86462.12601626, with a leftover of 8e-09.
