Let's divide 51133686 by 20
Let's see how many times 20 fits into 51133686.

Advancing to step 1:
20 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 20

Step 2:
When dividing 51 by 20, we get 2 with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 40 from 51 to get 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 20

Step 3:
20 can be fit into 111 5 times, resulting in a remainder of 11.
The next digit of our result is 5. 
Result so far: 25.0
If we take 100 away from 111, we end up with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 20

Moving on to step 4:
The number 20 fits into 113 5 times, leaving a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 255.0
The remainder is 13 after subtracting 100 from 113.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 20

Step 5:
The number 20 fits into 133 6 times, leaving a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 2556.0
Subtracting 120 from 133 leaves us with 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 20

Moving on to step 6:
When dividing 136 by 20, we get 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 25566.0
If we take 120 away from 136, we end up with 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 20

Step 7:
When dividing 168 by 20, we get 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 255668.0
If we take 160 away from 168, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 20

Advancing to step 8:
If we divide 86 by 20, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 2556684.0
Subtracting 80 from 86 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
20 can be fit into 60 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 2556684.3
Subtracting 60 from 60 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 2556684.3
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2556684.3
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 2556684.3 with a remaining 0.0.
