We look at the division of 985429 by 13 
We want to figure out the number of times 985429 can be divided by 13.

On to step 1:
If we divide 9 by 13, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 13

Step 2:
If we divide 98 by 13, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 91 from 98, we get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 13

Moving on to step 3:
13 goes into 75 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 75.0
Subtract 65 from 75 to get 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 13

Advancing to step 4:
The number 13 fits into 104 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 758.0
Subtract 104 from 104 to get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 13

Let's proceed to step 5:
The number 13 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 7580.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 13

Advancing to step 6:
13 goes into 29 2 times with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 75802.0
Deduct 26 from 29 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.

Let's proceed to step 7:
If we divide 30 by 13, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 75802.2
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 8:
13 goes into 40 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 75802.23
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.

On to step 9:
The number 13 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 75802.23
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.

Going ahead to step 10:
13 can be fit into 100 7 times, resulting in a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 75802.2307
Subtract 91 from 100 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 11:
13 goes into 90 6 times with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 75802.23076
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.

Step 12:
13 goes into 120 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 75802.230769
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.

Going ahead to step 13:
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: 75802.2307692
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.

Step 14:
If we divide 40 by 13, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 75802.23076923
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.

The final result is 75802.23076923 with a remainder of 1e-09.
