67988006 ÷ 990 
We want to figure out the number of times 67988006 can be divided by 990.

On to step 1:
When dividing 6 by 990, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 990

On to step 2:
If we divide 67 by 990, we get 0 and a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Take the next digit (9) from the dividend and append it to 67, then repeat: 679 / 990

On to step 3:
The number 990 fits into 679 0 times, leaving a remainder of 679.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 679 leaves us with 679.
Bring next digit (8) of the dividend behind the 679 and repeat the process: 6798 / 990

Step 4:
990 goes into 6798 6 times with a remainder of 858.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 5940 from 6798 to get 858.
Bring next digit (8) of the dividend behind the 858 and repeat the process: 8588 / 990

On to step 5:
990 can be fit into 8588 8 times, resulting in a remainder of 668.
Write down 8 as next digit of the result. 
Result so far: 68.0
Deduct 7920 from 8588 and we're left with 668.
Take the next digit (0) from the dividend and append it to 668, then repeat: 6680 / 990

Step 6:
990 goes into 6680 6 times with a remainder of 740.
Write down 6 as next digit of the result. 
Result so far: 686.0
Subtracting 5940 from 6680 leaves us with 740.
Take the next digit (0) from the dividend and append it to 740, then repeat: 7400 / 990

Going ahead to step 7:
7400 divided by 990 is 7 with a remainder of 470.
Record the quotient 7 as the next digit in the result. 
Result so far: 6867.0
If we take 6930 away from 7400, we end up with 470.
Append the next digit (6) from the dividend to 470 and continue with: 4706 / 990

Moving on to step 8:
If we divide 4706 by 990, we get 4 and a remainder of 746.
Record the quotient 4 as the next digit in the result. 
Result so far: 68674.0
Deduct 3960 from 4706 and we're left with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

Moving on to step 9:
7460 divided by 990 is 7 with a remainder of 530.
Use 7 as the next digit of our solution. 
Result so far: 68674.7
If we subtract 6930 from 7460, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 10:
990 can be fit into 5300 5 times, resulting in a remainder of 350.
Write down 5 as next digit of the result. 
Result so far: 68674.75
The remainder is 350 after subtracting 4950 from 5300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 11:
When dividing 3500 by 990, we get 3 with a remainder of 530.
The number 3 becomes the next digit in our result. 
Result so far: 68674.753
If we take 2970 away from 3500, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 12:
5300 divided by 990 is 5 with a remainder of 350.
Record the quotient 5 as the next digit in the result. 
Result so far: 68674.7535
Subtract 4950 from 5300 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 13:
When dividing 3500 by 990, we get 3 with a remainder of 530.
Write down 3 as next digit of the result. 
Result so far: 68674.75353
Deduct 2970 from 3500 and we're left with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 14:
990 can be fit into 5300 5 times, resulting in a remainder of 350.
Put 5 as the next digit of the answer. 
Result so far: 68674.753535
The remainder is 350 after subtracting 4950 from 5300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 15:
When dividing 3500 by 990, we get 3 with a remainder of 530.
Record the quotient 3 as the next digit in the result. 
Result so far: 68674.7535353
Subtracting 2970 from 3500 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 16:
990 can be fit into 5300 5 times, resulting in a remainder of 350.
The number 5 becomes the next digit in our result. 
Result so far: 68674.75353535
Deduct 4950 from 5300 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

After the division, we end up with 68674.75353535 and a remainder of 3.5e-07.
