We divide 51424 by 13
We're looking to find how many times 13 goes into 51424.

Step 1:
If we divide 5 by 13, we get 0 and 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.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 13

Advancing to step 2:
When dividing 51 by 13, we get 3 with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 12 after subtracting 39 from 51.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 13

Going ahead to step 3:
124 divided by 13 is 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we take 117 away from 124, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 13

On to step 4:
13 goes into 72 5 times with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 395.0
Subtract 65 from 72 to get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 13

Step 5:
74 divided by 13 is 5 with a remainder of 9.
The next digit of our result is 5. 
Result so far: 3955.0
Subtract 65 from 74 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 6:
13 goes into 90 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 3955.6
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
120 divided by 13 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 3955.69
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 8:
When dividing 30 by 13, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 3955.692
If we subtract 26 from 30, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
40 divided by 13 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3955.6923
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
13 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 3955.6923
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
13 can be fit into 100 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 3955.692307
If we subtract 91 from 100, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 12:
When dividing 90 by 13, we get 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 3955.6923076
The remainder is 12 after subtracting 78 from 90.
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 13:
13 goes into 120 9 times with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 3955.69230769
Subtracting 117 from 120 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 3955.69230769, with a leftover of 3e-09.
