Let's divide 51404628 by 36
Our goal is to divide 51404628 by 36.

On to step 1:
The number 36 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
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 / 36

Step 2:
When dividing 51 by 36, we get 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 36 from 51 and we're left with 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 36

Advancing to step 3:
36 can be fit into 154 4 times, resulting in a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 10 after subtracting 144 from 154.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 36

On to step 4:
The number 36 fits into 100 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 142.0
If we subtract 72 from 100, we get 28.
Grab the next digit (4) from the dividend, add it to 28, then carry on: 284 / 36

Moving on to step 5:
36 can be fit into 284 7 times, resulting in a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 1427.0
If we subtract 252 from 284, we get 32.
Grab the next digit (6) from the dividend, add it to 32, then carry on: 326 / 36

On to step 6:
When dividing 326 by 36, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 14279.0
Subtracting 324 from 326 leaves us with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 36

Step 7:
If we divide 22 by 36, we get 0 and a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 142790.0
If we take 0 away from 22, we end up with 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 36

Step 8:
228 divided by 36 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 1427906.0
If we subtract 216 from 228, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
When dividing 120 by 36, we get 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 1427906.3
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
The number 36 fits into 120 3 times, leaving a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 1427906.33
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 1427906.33, and the remainder is 0.012.
