99021612 divided by 689 
Our goal is to divide 99021612 by 689.

Step 1:
When dividing 9 by 689, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 689

Moving on to step 4:
The number 689 fits into 3012 4 times, leaving a remainder of 256.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 2756 from 3012, we get 256.
Bring next digit (1) of the dividend behind the 256 and repeat the process: 2561 / 689

Advancing to step 5:
When dividing 2561 by 689, we get 3 with a remainder of 494.
The number 3 becomes the next digit in our result. 
Result so far: 143.0
Deduct 2067 from 2561 and we're left with 494.
Grab the next digit (6) from the dividend, add it to 494, then carry on: 4946 / 689

On to step 6:
689 goes into 4946 7 times with a remainder of 123.
The number 7 becomes the next digit in our result. 
Result so far: 1437.0
Subtracting 4823 from 4946 leaves us with 123.
Bring next digit (1) of the dividend behind the 123 and repeat the process: 1231 / 689

Let's proceed to step 7:
689 can be fit into 1231 1 times, resulting in a remainder of 542.
Write down 1 as next digit of the result. 
Result so far: 14371.0
Deduct 689 from 1231 and we're left with 542.
Bring next digit (2) of the dividend behind the 542 and repeat the process: 5422 / 689

Advancing to step 8:
689 can be fit into 5422 7 times, resulting in a remainder of 599.
Write down 7 as next digit of the result. 
Result so far: 143717.0
Subtracting 4823 from 5422 leaves us with 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Step 9:
When dividing 5990 by 689, we get 8 with a remainder of 478.
Use 8 as the next digit of our solution. 
Result so far: 143717.8
Deduct 5512 from 5990 and we're left with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Advancing to step 10:
689 can be fit into 4780 6 times, resulting in a remainder of 646.
Use 6 as the next digit of our solution. 
Result so far: 143717.86
Deduct 4134 from 4780 and we're left with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Step 11:
689 can be fit into 6460 9 times, resulting in a remainder of 259.
The number 9 becomes the next digit in our result. 
Result so far: 143717.869
Subtract 6201 from 6460 to get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 12:
If we divide 2590 by 689, we get 3 and a remainder of 523.
Write down 3 as next digit of the result. 
Result so far: 143717.8693
Subtracting 2067 from 2590 leaves us with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Step 13:
If we divide 5230 by 689, we get 7 and a remainder of 407.
The next digit of our result is 7. 
Result so far: 143717.86937
The remainder is 407 after subtracting 4823 from 5230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

On to step 14:
The number 689 fits into 4070 5 times, leaving a remainder of 625.
The next digit of our result is 5. 
Result so far: 143717.869375
The remainder is 625 after subtracting 3445 from 4070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Let's proceed to step 15:
689 goes into 6250 9 times with a remainder of 49.
The next digit of our result is 9. 
Result so far: 143717.8693759
Subtract 6201 from 6250 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 16:
The number 689 fits into 490 0 times, leaving a remainder of 490.
Use 0 as the next digit of our solution. 
Result so far: 143717.8693759
The remainder is 490 after subtracting 0 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

The quotient of the division is 143717.8693759, and the remainder is 4.9e-07.
