We look at the division of 987001 by 990 
We want to figure out the number of times 987001 can be divided by 990.

On to step 1:
9 divided by 990 is 0 with a remainder of 9.
The next digit of our result is 0. 
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 / 990

On to step 2:
If we divide 98 by 990, we get 0 and a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 98, we end up with 98.
Include the next digit (7) from the dividend after 98, then repeat: 987 / 990

Going ahead to step 3:
990 can be fit into 987 0 times, resulting in a remainder of 987.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 987 after subtracting 0 from 987.
Fetch the next digit (0) from the dividend, attach it to 987 and continue: 9870 / 990

On to step 4:
If we divide 9870 by 990, we get 9 and a remainder of 960.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 8910 from 9870, we get 960.
Append the next digit (0) from the dividend to 960 and continue with: 9600 / 990

Advancing to step 5:
990 goes into 9600 9 times with a remainder of 690.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Deduct 8910 from 9600 and we're left with 690.
Append the next digit (1) from the dividend to 690 and continue with: 6901 / 990

Advancing to step 6:
990 can be fit into 6901 6 times, resulting in a remainder of 961.
Put 6 as the next digit of the answer. 
Result so far: 996.0
The remainder is 961 after subtracting 5940 from 6901.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9610, and continue the process.

Moving on to step 7:
When dividing 9610 by 990, we get 9 with a remainder of 700.
Use 9 as the next digit of our solution. 
Result so far: 996.9
If we take 8910 away from 9610, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 8:
The number 990 fits into 7000 7 times, leaving a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 996.97
Subtracting 6930 from 7000 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 9:
990 can be fit into 700 0 times, resulting in a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 996.97
The remainder is 700 after subtracting 0 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 10:
The number 990 fits into 7000 7 times, leaving a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 996.9707
The remainder is 70 after subtracting 6930 from 7000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
If we divide 700 by 990, we get 0 and a remainder of 700.
The number 0 becomes the next digit in our result. 
Result so far: 996.9707
Deduct 0 from 700 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 12:
990 can be fit into 7000 7 times, resulting in a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 996.970707
Subtracting 6930 from 7000 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 13:
990 can be fit into 700 0 times, resulting in a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 996.970707
Subtracting 0 from 700 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 14:
7000 divided by 990 is 7 with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 996.97070707
If we subtract 6930 from 7000, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 996.97070707 with a balance of 7e-08.
