988589 ÷ 15 
We want to figure out the number of times 988589 can be divided by 15.

Going ahead to step 1:
If we divide 9 by 15, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 15

Let's proceed to step 2:
The number 15 fits into 98 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 90 away from 98, we end up with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 15

Step 3:
88 divided by 15 is 5 with a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 65.0
Deduct 75 from 88 and we're left with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 15

Step 4:
15 goes into 135 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 659.0
Deduct 135 from 135 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 15

Moving on to step 5:
15 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 6590.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 15

Advancing to step 6:
If we divide 89 by 15, we get 5 and a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 65905.0
Deduct 75 from 89 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
When dividing 140 by 15, we get 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 65905.9
If we take 135 away from 140, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
15 goes into 50 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 65905.93
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
If we divide 50 by 15, we get 3 and a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 65905.933
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 65905.933 with a balance of 0.0005.
