We're dividing 64548943 by 13 
We want to divide 64548943 by 13.

Advancing to step 1:
6 divided by 13 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 13

On to step 2:
The number 13 fits into 64 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 52 from 64 to get 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 13

Advancing to step 3:
The number 13 fits into 125 9 times, leaving a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we take 117 away from 125, we end up with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 13

On to step 4:
84 divided by 13 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 496.0
Deduct 78 from 84 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 13

Let's proceed to step 5:
If we divide 68 by 13, we get 5 and a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 4965.0
Subtract 65 from 68 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 13

Going ahead to step 6:
39 divided by 13 is 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 49653.0
Subtract 39 from 39 to get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 13

Advancing to step 7:
When dividing 4 by 13, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 496530.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 13

Moving on to step 8:
43 divided by 13 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 4965303.0
Subtracting 39 from 43 leaves us 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.

Step 9:
40 divided by 13 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 4965303.3
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.

Going ahead to step 10:
The number 13 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 4965303.3
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.

Advancing to step 11:
100 divided by 13 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 4965303.307
Subtracting 91 from 100 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 12:
When dividing 90 by 13, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 4965303.3076
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 13:
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: 4965303.30769
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.

Advancing to step 14:
13 can be fit into 30 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 4965303.307692
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.

Let's proceed to step 15:
13 goes into 40 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 4965303.3076923
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.

Moving on to step 16:
10 divided by 13 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 4965303.3076923
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.

The final result is 4965303.3076923 with a remainder of 1e-08.
