We look at the division of 990999 by 60 
Our goal is to divide 990999 by 60.

Step 1:
The number 60 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 60

On to step 2:
When dividing 99 by 60, we get 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 60 from 99 and we're left with 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 60

Step 3:
When dividing 390 by 60, we get 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 30 after subtracting 360 from 390.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 60

On to step 4:
If we divide 309 by 60, we get 5 and a remainder of 9.
The next digit of our result is 5. 
Result so far: 165.0
If we subtract 300 from 309, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 60

On to step 5:
60 goes into 99 1 times with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1651.0
Subtracting 60 from 99 leaves us with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 60

Moving on to step 6:
If we divide 399 by 60, we get 6 and a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 16516.0
If we subtract 360 from 399, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 7:
If we divide 390 by 60, we get 6 and a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 16516.6
If we take 360 away from 390, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
The number 60 fits into 300 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 16516.65
Subtracting 300 from 300 leaves us 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.

Moving on to step 9:
60 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16516.65
If we take 0 away from 0, we end up 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.

Let's proceed to step 10:
The number 60 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 16516.65
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.

The quotient of the division is 16516.65, and the remainder is 0.0.
