We look at the division of 42369342 by 636 
We're looking to find how many times 636 goes into 42369342.

Advancing to step 1:
636 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 636

Moving on to step 2:
636 can be fit into 42 0 times, resulting in a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 636

Going ahead to step 3:
The number 636 fits into 423 0 times, leaving a remainder of 423.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 423 leaves us with 423.
Bring next digit (6) of the dividend behind the 423 and repeat the process: 4236 / 636

Let's proceed to step 4:
636 can be fit into 4236 6 times, resulting in a remainder of 420.
The next digit of our result is 6. 
Result so far: 6.0
If we take 3816 away from 4236, we end up with 420.
Take the next digit (9) from the dividend and append it to 420, then repeat: 4209 / 636

Step 5:
The number 636 fits into 4209 6 times, leaving a remainder of 393.
Write down 6 as next digit of the result. 
Result so far: 66.0
If we take 3816 away from 4209, we end up with 393.
Grab the next digit (3) from the dividend, add it to 393, then carry on: 3933 / 636

Step 6:
636 can be fit into 3933 6 times, resulting in a remainder of 117.
The next digit of our result is 6. 
Result so far: 666.0
Subtract 3816 from 3933 to get 117.
Bring next digit (4) of the dividend behind the 117 and repeat the process: 1174 / 636

Step 7:
636 can be fit into 1174 1 times, resulting in a remainder of 538.
Use 1 as the next digit of our solution. 
Result so far: 6661.0
If we subtract 636 from 1174, we get 538.
Bring next digit (2) of the dividend behind the 538 and repeat the process: 5382 / 636

Moving on to step 8:
The number 636 fits into 5382 8 times, leaving a remainder of 294.
The number 8 becomes the next digit in our result. 
Result so far: 66618.0
Deduct 5088 from 5382 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 9:
When dividing 2940 by 636, we get 4 with a remainder of 396.
Put 4 as the next digit of the answer. 
Result so far: 66618.4
Subtracting 2544 from 2940 leaves us with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 10:
636 goes into 3960 6 times with a remainder of 144.
Use 6 as the next digit of our solution. 
Result so far: 66618.46
Subtract 3816 from 3960 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 11:
The number 636 fits into 1440 2 times, leaving a remainder of 168.
Write down 2 as next digit of the result. 
Result so far: 66618.462
Subtract 1272 from 1440 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 12:
636 can be fit into 1680 2 times, resulting in a remainder of 408.
Record the quotient 2 as the next digit in the result. 
Result so far: 66618.4622
Subtracting 1272 from 1680 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

The final outcome is 66618.4622, with a leftover of 0.00408.
