We look at the division of 99504638 by 689 
We want to figure out the number of times 99504638 can be divided by 689.

On to step 1:
689 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 689

Step 2:
689 goes into 99 0 times with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Bring next digit (5) of the dividend behind the 99 and repeat the process: 995 / 689

On to step 3:
689 can be fit into 995 1 times, resulting in a remainder of 306.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 689 from 995 leaves us with 306.
Fetch the next digit (0) from the dividend, attach it to 306 and continue: 3060 / 689

Advancing to step 4:
When dividing 3060 by 689, we get 4 with a remainder of 304.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 304 after subtracting 2756 from 3060.
Take the next digit (4) from the dividend and append it to 304, then repeat: 3044 / 689

Step 5:
The number 689 fits into 3044 4 times, leaving a remainder of 288.
Write down 4 as next digit of the result. 
Result so far: 144.0
Deduct 2756 from 3044 and we're left with 288.
Fetch the next digit (6) from the dividend, attach it to 288 and continue: 2886 / 689

Advancing to step 6:
689 can be fit into 2886 4 times, resulting in a remainder of 130.
The next digit of our result is 4. 
Result so far: 1444.0
The remainder is 130 after subtracting 2756 from 2886.
Grab the next digit (3) from the dividend, add it to 130, then carry on: 1303 / 689

Advancing to step 7:
The number 689 fits into 1303 1 times, leaving a remainder of 614.
Write down 1 as next digit of the result. 
Result so far: 14441.0
Subtract 689 from 1303 to get 614.
Append the next digit (8) from the dividend to 614 and continue with: 6148 / 689

Going ahead to step 8:
The number 689 fits into 6148 8 times, leaving a remainder of 636.
Use 8 as the next digit of our solution. 
Result so far: 144418.0
If we subtract 5512 from 6148, we get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Step 9:
When dividing 6360 by 689, we get 9 with a remainder of 159.
The number 9 becomes the next digit in our result. 
Result so far: 144418.9
Subtracting 6201 from 6360 leaves us with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Going ahead to step 10:
The number 689 fits into 1590 2 times, leaving a remainder of 212.
Use 2 as the next digit of our solution. 
Result so far: 144418.92
If we subtract 1378 from 1590, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 11:
The number 689 fits into 2120 3 times, leaving a remainder of 53.
The next digit of our result is 3. 
Result so far: 144418.923
If we take 2067 away from 2120, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 12:
530 divided by 689 is 0 with a remainder of 530.
Record the quotient 0 as the next digit in the result. 
Result so far: 144418.923
Subtracting 0 from 530 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.

Moving on to step 13:
689 goes into 5300 7 times with a remainder of 477.
Put 7 as the next digit of the answer. 
Result so far: 144418.92307
Subtract 4823 from 5300 to get 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Advancing to step 14:
If we divide 4770 by 689, we get 6 and a remainder of 636.
Use 6 as the next digit of our solution. 
Result so far: 144418.923076
If we subtract 4134 from 4770, we get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Step 15:
When dividing 6360 by 689, we get 9 with a remainder of 159.
Put 9 as the next digit of the answer. 
Result so far: 144418.9230769
If we subtract 6201 from 6360, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Going ahead to step 16:
689 can be fit into 1590 2 times, resulting in a remainder of 212.
Write down 2 as next digit of the result. 
Result so far: 144418.92307692
Deduct 1378 from 1590 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The quotient of the division is 144418.92307692, and the remainder is 2.12e-07.
