99608315 divided by 13 
We want to divide 99608315 by 13.

On to step 1:
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: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 13

Advancing to step 2:
13 can be fit into 99 7 times, resulting in a remainder of 8.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 91 from 99, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 13

Going ahead to step 3:
13 can be fit into 86 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 76.0
Subtracting 78 from 86 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 13

Moving on to step 4:
13 goes into 80 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 766.0
The remainder is 2 after subtracting 78 from 80.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 13

Step 5:
13 can be fit into 28 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 7662.0
Subtract 26 from 28 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 13

Moving on to step 6:
13 can be fit into 23 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 76621.0
If we take 13 away from 23, we end up with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 13

Moving on to step 7:
101 divided by 13 is 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 766217.0
Subtract 91 from 101 to get 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 13

Step 8:
When dividing 105 by 13, we get 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 7662178.0
Subtract 104 from 105 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.

Step 9:
When dividing 10 by 13, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 7662178.0
Deduct 0 from 10 and we're left with 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 10:
13 goes into 100 7 times with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 7662178.07
Deduct 91 from 100 and we're left 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 11:
90 divided by 13 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 7662178.076
Subtract 78 from 90 to 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.

On to step 12:
If we divide 120 by 13, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 7662178.0769
Deduct 117 from 120 and we're left 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.

Moving on to step 13:
When dividing 30 by 13, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 7662178.07692
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.

Going ahead to step 14:
When dividing 40 by 13, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 7662178.076923
If we subtract 39 from 40, we 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.

Advancing to step 15:
13 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 7662178.076923
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.

Advancing to step 16:
The number 13 fits into 100 7 times, leaving a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 7662178.07692307
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.

The quotient of the division is 7662178.07692307, and the remainder is 9e-09.
