We look at the division of 54042102 by 636 
We're looking to find how many times 636 goes into 54042102.

Moving on to step 1:
636 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 636

Moving on to step 2:
When dividing 54 by 636, we get 0 with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Include the next digit (0) from the dividend after 54, then repeat: 540 / 636

Moving on to step 3:
636 can be fit into 540 0 times, resulting in a remainder of 540.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 540 after subtracting 0 from 540.
Fetch the next digit (4) from the dividend, attach it to 540 and continue: 5404 / 636

On to step 4:
When dividing 5404 by 636, we get 8 with a remainder of 316.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 5088 from 5404 and we're left with 316.
Grab the next digit (2) from the dividend, add it to 316, then carry on: 3162 / 636

Let's proceed to step 5:
3162 divided by 636 is 4 with a remainder of 618.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
The remainder is 618 after subtracting 2544 from 3162.
Include the next digit (1) from the dividend after 618, then repeat: 6181 / 636

On to step 6:
636 goes into 6181 9 times with a remainder of 457.
Record the quotient 9 as the next digit in the result. 
Result so far: 849.0
If we subtract 5724 from 6181, we get 457.
Fetch the next digit (0) from the dividend, attach it to 457 and continue: 4570 / 636

Let's proceed to step 7:
4570 divided by 636 is 7 with a remainder of 118.
Put 7 as the next digit of the answer. 
Result so far: 8497.0
If we take 4452 away from 4570, we end up with 118.
Fetch the next digit (2) from the dividend, attach it to 118 and continue: 1182 / 636

Moving on to step 8:
636 can be fit into 1182 1 times, resulting in a remainder of 546.
Record the quotient 1 as the next digit in the result. 
Result so far: 84971.0
Subtracting 636 from 1182 leaves us with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Moving on to step 9:
5460 divided by 636 is 8 with a remainder of 372.
Write down 8 as next digit of the result. 
Result so far: 84971.8
Subtracting 5088 from 5460 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Moving on to step 10:
636 can be fit into 3720 5 times, resulting in a remainder of 540.
Use 5 as the next digit of our solution. 
Result so far: 84971.85
The remainder is 540 after subtracting 3180 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Let's proceed to step 11:
If we divide 5400 by 636, we get 8 and a remainder of 312.
Record the quotient 8 as the next digit in the result. 
Result so far: 84971.858
If we take 5088 away from 5400, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 12:
636 goes into 3120 4 times with a remainder of 576.
Record the quotient 4 as the next digit in the result. 
Result so far: 84971.8584
Subtract 2544 from 3120 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 13:
If we divide 5760 by 636, we get 9 and a remainder of 36.
The next digit of our result is 9. 
Result so far: 84971.85849
Subtract 5724 from 5760 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
636 can be fit into 360 0 times, resulting in a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 84971.85849
Deduct 0 from 360 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 15:
636 goes into 3600 5 times with a remainder of 420.
Put 5 as the next digit of the answer. 
Result so far: 84971.8584905
Subtract 3180 from 3600 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 16:
636 goes into 4200 6 times with a remainder of 384.
Use 6 as the next digit of our solution. 
Result so far: 84971.85849056
If we subtract 3816 from 4200, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The final outcome is 84971.85849056, with a leftover of 3.84e-07.
