We divide 691990 by 99
We're looking to find how many times 99 goes into 691990.

Moving on to step 1:
When dividing 6 by 99, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 99

On to step 2:
99 can be fit into 69 0 times, resulting in a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Include the next digit (1) from the dividend after 69, then repeat: 691 / 99

Going ahead to step 3:
When dividing 691 by 99, we get 6 with a remainder of 97.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 594 from 691 to get 97.
Append the next digit (9) from the dividend to 97 and continue with: 979 / 99

On to step 4:
When dividing 979 by 99, we get 9 with a remainder of 88.
Use 9 as the next digit of our solution. 
Result so far: 69.0
The remainder is 88 after subtracting 891 from 979.
Bring next digit (9) of the dividend behind the 88 and repeat the process: 889 / 99

Let's proceed to step 5:
The number 99 fits into 889 8 times, leaving a remainder of 97.
Write down 8 as next digit of the result. 
Result so far: 698.0
If we subtract 792 from 889, we get 97.
Append the next digit (0) from the dividend to 97 and continue with: 970 / 99

On to step 6:
99 goes into 970 9 times with a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 6989.0
If we subtract 891 from 970, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 7:
99 goes into 790 7 times with a remainder of 97.
Put 7 as the next digit of the answer. 
Result so far: 6989.7
Subtracting 693 from 790 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 8:
If we divide 970 by 99, we get 9 and a remainder of 79.
The number 9 becomes the next digit in our result. 
Result so far: 6989.79
Subtracting 891 from 970 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 9:
99 goes into 790 7 times with a remainder of 97.
Write down 7 as next digit of the result. 
Result so far: 6989.797
The remainder is 97 after subtracting 693 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

On to step 10:
When dividing 970 by 99, we get 9 with a remainder of 79.
Write down 9 as next digit of the result. 
Result so far: 6989.7979
If we take 891 away from 970, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 11:
99 can be fit into 790 7 times, resulting in a remainder of 97.
Write down 7 as next digit of the result. 
Result so far: 6989.79797
If we subtract 693 from 790, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Going ahead to step 12:
99 goes into 970 9 times with a remainder of 79.
The next digit of our result is 9. 
Result so far: 6989.797979
Subtracting 891 from 970 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 13:
If we divide 790 by 99, we get 7 and a remainder of 97.
The next digit of our result is 7. 
Result so far: 6989.7979797
Subtract 693 from 790 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Moving on to step 14:
99 goes into 970 9 times with a remainder of 79.
Record the quotient 9 as the next digit in the result. 
Result so far: 6989.79797979
If we take 891 away from 970, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

In conclusion, the division gives 6989.79797979 with a balance of 7.9e-08.
