54189013 divided by 13 
We want to figure out the number of times 54189013 can be divided by 13.

Moving on to step 1:
5 divided by 13 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 13

Let's proceed to step 2:
13 goes into 54 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 52 from 54, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 13

Advancing to step 3:
13 can be fit into 21 1 times, resulting in a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Subtract 13 from 21 to get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 13

Going ahead to step 4:
The number 13 fits into 88 6 times, leaving a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 416.0
Subtracting 78 from 88 leaves us with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 13

Moving on to step 5:
13 can be fit into 109 8 times, resulting in a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 4168.0
Subtracting 104 from 109 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 13

Let's proceed to step 6:
If we divide 50 by 13, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 41683.0
If we take 39 away from 50, we end up with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 13

On to step 7:
13 goes into 111 8 times with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 416838.0
Subtract 104 from 111 to get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 13

Going ahead to step 8:
73 divided by 13 is 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 4168385.0
If we subtract 65 from 73, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
When dividing 80 by 13, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 4168385.6
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
If we divide 20 by 13, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 4168385.61
Subtracting 13 from 20 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 11:
13 goes into 70 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 4168385.615
If we take 65 away from 70, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
When dividing 50 by 13, we get 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 4168385.6153
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 13:
13 can be fit into 110 8 times, resulting in a remainder of 6.
The next digit of our result is 8. 
Result so far: 4168385.61538
Deduct 104 from 110 and we're left 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.

Moving on to step 14:
When dividing 60 by 13, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 4168385.615384
Deduct 52 from 60 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 15:
13 can be fit into 80 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 4168385.6153846
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 16:
The number 13 fits into 20 1 times, leaving a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 4168385.61538461
If we take 13 away from 20, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 4168385.61538461, with a leftover of 7e-09.
