70499945 ÷ 13 
We want to figure out the number of times 70499945 can be divided by 13.

Let's proceed to step 1:
If we divide 7 by 13, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 13

Going ahead to step 2:
13 can be fit into 70 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 65 away from 70, we end up with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 13

Going ahead to step 3:
If we divide 54 by 13, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 54.0
The remainder is 2 after subtracting 52 from 54.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 13

Moving on to step 4:
13 can be fit into 29 2 times, resulting in a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 542.0
Subtract 26 from 29 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 13

Let's proceed to step 5:
39 divided by 13 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 5423.0
The remainder is 0 after subtracting 39 from 39.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 13

Let's proceed to step 6:
If we divide 9 by 13, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 54230.0
If we subtract 0 from 9, we get 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 13

Advancing to step 7:
13 goes into 94 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 542307.0
Deduct 91 from 94 and we're left with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 13

Step 8:
When dividing 35 by 13, we get 2 with a remainder of 9.
The next digit of our result is 2. 
Result so far: 5423072.0
Subtract 26 from 35 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.

On to step 9:
When dividing 90 by 13, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 5423072.6
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.

On to step 10:
120 divided by 13 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 5423072.69
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.

On to step 11:
13 goes into 30 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 5423072.692
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.

Let's proceed to step 12:
The number 13 fits into 40 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 5423072.6923
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.

Step 13:
13 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 5423072.6923
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
13 can be fit into 100 7 times, resulting in a remainder of 9.
The next digit of our result is 7. 
Result so far: 5423072.692307
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.

On to step 15:
13 goes into 90 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 5423072.6923076
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:
When dividing 120 by 13, we get 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 5423072.69230769
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.

The quotient of the division is 5423072.69230769, and the remainder is 3e-09.
