We look at the division of 901915 by 13 
We want to figure out the number of times 901915 can be divided by 13.

Let's proceed to step 1:
13 can be fit into 9 0 times, resulting in 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 (0) of the dividend behind the 9 and repeat the process: 90 / 13

Going ahead to step 2:
When dividing 90 by 13, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 78 from 90 and we're left with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 13

Let's proceed to step 3:
13 goes into 121 9 times with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 69.0
The remainder is 4 after subtracting 117 from 121.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 13

Let's proceed to step 4:
If we divide 49 by 13, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 693.0
If we subtract 39 from 49, we get 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 13

Moving on to step 5:
101 divided by 13 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 6937.0
Subtract 91 from 101 to get 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 13

Let's proceed to step 6:
105 divided by 13 is 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 69378.0
If we take 104 away from 105, we end up 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 7:
The number 13 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 69378.0
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.

Going ahead to step 8:
When dividing 100 by 13, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 69378.07
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.

Let's proceed to step 9:
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: 69378.076
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.

Step 10:
120 divided by 13 is 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 69378.0769
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.

On to step 11:
The number 13 fits into 30 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 69378.07692
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.

Step 12:
13 can be fit into 40 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 69378.076923
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.

Step 13:
13 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 69378.076923
Subtracting 0 from 10 leaves us 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.

Step 14:
If we divide 100 by 13, we get 7 and a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 69378.07692307
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.

In conclusion, the division gives 69378.07692307 with a balance of 9e-09.
