We're dividing 20689494 by 15 
We want to divide 20689494 by 15.

Step 1:
When dividing 2 by 15, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 15

Going ahead to step 2:
15 can be fit into 20 1 times, resulting in a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 15 from 20 to get 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 15

Advancing to step 3:
15 can be fit into 56 3 times, resulting in a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 45 from 56, we get 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 15

Moving on to step 4:
15 can be fit into 118 7 times, resulting in a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 137.0
Deduct 105 from 118 and we're left with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 15

On to step 5:
When dividing 139 by 15, we get 9 with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 1379.0
Deduct 135 from 139 and we're left with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 15

Let's proceed to step 6:
44 divided by 15 is 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 13792.0
If we take 30 away from 44, we end up with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 15

Advancing to step 7:
15 goes into 149 9 times with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 137929.0
If we subtract 135 from 149, we get 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 15

On to step 8:
15 can be fit into 144 9 times, resulting in a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 1379299.0
If we subtract 135 from 144, 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.

Advancing to step 9:
90 divided by 15 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 1379299.6
If we subtract 90 from 90, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
If we divide 0 by 15, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1379299.6
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
15 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1379299.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 1379299.6 and a remainder of 0.0.
