Let's divide 51202407 by 636
Let's see how many times 636 fits into 51202407.

On to step 1:
If we divide 5 by 636, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 636

Going ahead to step 2:
636 can be fit into 51 0 times, resulting in a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Fetch the next digit (2) from the dividend, attach it to 51 and continue: 512 / 636

Moving on to step 3:
If we divide 512 by 636, we get 0 and a remainder of 512.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 512 to get 512.
Take the next digit (0) from the dividend and append it to 512, then repeat: 5120 / 636

Advancing to step 4:
The number 636 fits into 5120 8 times, leaving a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 32 after subtracting 5088 from 5120.
Include the next digit (2) from the dividend after 32, then repeat: 322 / 636

On to step 5:
636 can be fit into 322 0 times, resulting in a remainder of 322.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Subtract 0 from 322 to get 322.
Take the next digit (4) from the dividend and append it to 322, then repeat: 3224 / 636

Step 6:
636 goes into 3224 5 times with a remainder of 44.
Write down 5 as next digit of the result. 
Result so far: 805.0
Subtract 3180 from 3224 to get 44.
Grab the next digit (0) from the dividend, add it to 44, then carry on: 440 / 636

Advancing to step 7:
636 can be fit into 440 0 times, resulting in a remainder of 440.
The number 0 becomes the next digit in our result. 
Result so far: 8050.0
Deduct 0 from 440 and we're left with 440.
Append the next digit (7) from the dividend to 440 and continue with: 4407 / 636

Moving on to step 8:
636 goes into 4407 6 times with a remainder of 591.
Record the quotient 6 as the next digit in the result. 
Result so far: 80506.0
Subtracting 3816 from 4407 leaves us with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Moving on to step 9:
When dividing 5910 by 636, we get 9 with a remainder of 186.
Record the quotient 9 as the next digit in the result. 
Result so far: 80506.9
Subtract 5724 from 5910 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 10:
1860 divided by 636 is 2 with a remainder of 588.
Write down 2 as next digit of the result. 
Result so far: 80506.92
Subtracting 1272 from 1860 leaves us with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Moving on to step 11:
When dividing 5880 by 636, we get 9 with a remainder of 156.
Write down 9 as next digit of the result. 
Result so far: 80506.929
Deduct 5724 from 5880 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 12:
The number 636 fits into 1560 2 times, leaving a remainder of 288.
The number 2 becomes the next digit in our result. 
Result so far: 80506.9292
If we subtract 1272 from 1560, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 13:
2880 divided by 636 is 4 with a remainder of 336.
Record the quotient 4 as the next digit in the result. 
Result so far: 80506.92924
If we take 2544 away from 2880, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 14:
The number 636 fits into 3360 5 times, leaving a remainder of 180.
Record the quotient 5 as the next digit in the result. 
Result so far: 80506.929245
The remainder is 180 after subtracting 3180 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 15:
636 can be fit into 1800 2 times, resulting in a remainder of 528.
Use 2 as the next digit of our solution. 
Result so far: 80506.9292452
If we take 1272 away from 1800, we end up with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 16:
The number 636 fits into 5280 8 times, leaving a remainder of 192.
The number 8 becomes the next digit in our result. 
Result so far: 80506.92924528
If we subtract 5088 from 5280, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

After the division, we end up with 80506.92924528 and a remainder of 1.92e-07.
