We look at the division of 99309776 by 690 
Our goal is to divide 99309776 by 690.

On to step 1:
If we divide 9 by 690, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 690

Going ahead to step 2:
If we divide 99 by 690, we get 0 and a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Fetch the next digit (3) from the dividend, attach it to 99 and continue: 993 / 690

Step 3:
690 can be fit into 993 1 times, resulting in a remainder of 303.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 690 from 993, we get 303.
Fetch the next digit (0) from the dividend, attach it to 303 and continue: 3030 / 690

On to step 4:
690 goes into 3030 4 times with a remainder of 270.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 2760 from 3030 leaves us with 270.
Include the next digit (9) from the dividend after 270, then repeat: 2709 / 690

Let's proceed to step 5:
If we divide 2709 by 690, we get 3 and a remainder of 639.
Use 3 as the next digit of our solution. 
Result so far: 143.0
Deduct 2070 from 2709 and we're left with 639.
Include the next digit (7) from the dividend after 639, then repeat: 6397 / 690

Moving on to step 6:
If we divide 6397 by 690, we get 9 and a remainder of 187.
Put 9 as the next digit of the answer. 
Result so far: 1439.0
If we subtract 6210 from 6397, we get 187.
Append the next digit (7) from the dividend to 187 and continue with: 1877 / 690

Step 7:
690 goes into 1877 2 times with a remainder of 497.
The number 2 becomes the next digit in our result. 
Result so far: 14392.0
If we take 1380 away from 1877, we end up with 497.
Take the next digit (6) from the dividend and append it to 497, then repeat: 4976 / 690

Moving on to step 8:
If we divide 4976 by 690, we get 7 and a remainder of 146.
Write down 7 as next digit of the result. 
Result so far: 143927.0
The remainder is 146 after subtracting 4830 from 4976.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 9:
690 can be fit into 1460 2 times, resulting in a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 143927.2
The remainder is 80 after subtracting 1380 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
The number 690 fits into 800 1 times, leaving a remainder of 110.
Put 1 as the next digit of the answer. 
Result so far: 143927.21
If we subtract 690 from 800, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 11:
If we divide 1100 by 690, we get 1 and a remainder of 410.
The next digit of our result is 1. 
Result so far: 143927.211
Subtract 690 from 1100 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

The final result is 143927.211 with a remainder of 0.041.
