We look at the division of 690542 by 99 
We want to divide 690542 by 99.

Step 1:
When dividing 6 by 99, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 99

Going ahead to step 2:
99 goes into 69 0 times with a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Bring next digit (0) of the dividend behind the 69 and repeat the process: 690 / 99

Advancing to step 3:
When dividing 690 by 99, we get 6 with a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 594 away from 690, we end up with 96.
Take the next digit (5) from the dividend and append it to 96, then repeat: 965 / 99

Step 4:
99 goes into 965 9 times with a remainder of 74.
Put 9 as the next digit of the answer. 
Result so far: 69.0
Subtracting 891 from 965 leaves us with 74.
Append the next digit (4) from the dividend to 74 and continue with: 744 / 99

Step 5:
99 can be fit into 744 7 times, resulting in a remainder of 51.
Use 7 as the next digit of our solution. 
Result so far: 697.0
The remainder is 51 after subtracting 693 from 744.
Take the next digit (2) from the dividend and append it to 51, then repeat: 512 / 99

Step 6:
512 divided by 99 is 5 with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 6975.0
If we subtract 495 from 512, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
99 can be fit into 170 1 times, resulting in a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 6975.1
The remainder is 71 after subtracting 99 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 8:
99 goes into 710 7 times with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 6975.17
Deduct 693 from 710 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 9:
If we divide 170 by 99, we get 1 and a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 6975.171
Subtract 99 from 170 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 10:
If we divide 710 by 99, we get 7 and a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 6975.1717
Subtract 693 from 710 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 11:
If we divide 170 by 99, we get 1 and a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 6975.17171
If we subtract 99 from 170, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 12:
The number 99 fits into 710 7 times, leaving a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 6975.171717
Deduct 693 from 710 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 13:
If we divide 170 by 99, we get 1 and a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 6975.1717171
Deduct 99 from 170 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 14:
99 can be fit into 710 7 times, resulting in a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 6975.17171717
Deduct 693 from 710 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 6975.17171717 with a remainder of 1.7e-08.
