Let's divide 87364416 by 13
We want to figure out the number of times 87364416 can be divided by 13.

Advancing to step 1:
If we divide 8 by 13, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 13

Let's proceed to step 2:
87 divided by 13 is 6 with a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 9 after subtracting 78 from 87.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 13

Advancing to step 3:
The number 13 fits into 93 7 times, leaving a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 67.0
Subtracting 91 from 93 leaves us with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 13

Advancing to step 4:
26 divided by 13 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 672.0
If we take 26 away from 26, we end up with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 13

Advancing to step 5:
4 divided by 13 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 6720.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 13

Moving on to step 6:
When dividing 44 by 13, we get 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 67203.0
Subtracting 39 from 44 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 13

Moving on to step 7:
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: 672033.0
Deduct 39 from 51 and we're left with 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 13

Advancing to step 8:
126 divided by 13 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 6720339.0
Subtracting 117 from 126 leaves us with 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 9:
90 divided by 13 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 6720339.6
If we subtract 78 from 90, 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.

Going ahead to step 10:
When dividing 120 by 13, we get 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 6720339.69
The remainder is 3 after subtracting 117 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 11:
If we divide 30 by 13, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 6720339.692
If we take 26 away from 30, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
When dividing 40 by 13, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 6720339.6923
Deduct 39 from 40 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 13:
The number 13 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 6720339.6923
If we subtract 0 from 10, we 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.

On to step 14:
13 goes into 100 7 times with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 6720339.692307
The remainder is 9 after subtracting 91 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 15:
When dividing 90 by 13, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 6720339.6923076
Deduct 78 from 90 and we're left with 12.
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 16:
13 goes into 120 9 times with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 6720339.69230769
Subtract 117 from 120 to 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.

The final outcome is 6720339.69230769, with a leftover of 3e-09.
