98121799 ÷ 13 
We want to divide 98121799 by 13.

Going ahead to step 1:
The number 13 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 13

Let's proceed to step 2:
If we divide 98 by 13, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 91 from 98, we get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 13

Step 3:
13 goes into 71 5 times with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Subtract 65 from 71 to get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 13

Advancing to step 4:
If we divide 62 by 13, we get 4 and a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 754.0
The remainder is 10 after subtracting 52 from 62.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 13

On to step 5:
The number 13 fits into 101 7 times, leaving a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 7547.0
If we subtract 91 from 101, we get 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 13

Going ahead to step 6:
The number 13 fits into 107 8 times, leaving a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 75478.0
If we take 104 away from 107, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 13

Moving on to step 7:
13 goes into 39 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 754783.0
The remainder is 0 after subtracting 39 from 39.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 13

Step 8:
The number 13 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 7547830.0
Deduct 0 from 9 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.

On to step 9:
When dividing 90 by 13, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 7547830.6
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.

Advancing to step 10:
13 goes into 120 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 7547830.69
If we take 117 away from 120, we end up 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.

On to step 11:
When dividing 30 by 13, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 7547830.692
Subtracting 26 from 30 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.

Let's proceed 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: 7547830.6923
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.
Use 0 as the next digit of our solution. 
Result so far: 7547830.6923
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.

Step 14:
13 goes into 100 7 times with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 7547830.692307
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 15:
13 goes into 90 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 7547830.6923076
Subtracting 78 from 90 leaves us 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.

Advancing to step 16:
The number 13 fits into 120 9 times, leaving a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 7547830.69230769
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.

In conclusion, the division gives 7547830.69230769 with a balance of 3e-09.
