99646868 divided by 690 
We want to figure out the number of times 99646868 can be divided by 690.

Going ahead to step 1:
690 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 690

Step 2:
The number 690 fits into 99 0 times, leaving a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Fetch the next digit (6) from the dividend, attach it to 99 and continue: 996 / 690

Going ahead to step 3:
The number 690 fits into 996 1 times, leaving a remainder of 306.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 690 from 996 to get 306.
Bring next digit (4) of the dividend behind the 306 and repeat the process: 3064 / 690

On to step 4:
3064 divided by 690 is 4 with a remainder of 304.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 2760 away from 3064, we end up with 304.
Grab the next digit (6) from the dividend, add it to 304, then carry on: 3046 / 690

Step 5:
690 can be fit into 3046 4 times, resulting in a remainder of 286.
Write down 4 as next digit of the result. 
Result so far: 144.0
Subtract 2760 from 3046 to get 286.
Include the next digit (8) from the dividend after 286, then repeat: 2868 / 690

Moving on to step 6:
690 can be fit into 2868 4 times, resulting in a remainder of 108.
The next digit of our result is 4. 
Result so far: 1444.0
If we subtract 2760 from 2868, we get 108.
Grab the next digit (6) from the dividend, add it to 108, then carry on: 1086 / 690

Let's proceed to step 7:
If we divide 1086 by 690, we get 1 and a remainder of 396.
The next digit of our result is 1. 
Result so far: 14441.0
The remainder is 396 after subtracting 690 from 1086.
Fetch the next digit (8) from the dividend, attach it to 396 and continue: 3968 / 690

Let's proceed to step 8:
When dividing 3968 by 690, we get 5 with a remainder of 518.
Record the quotient 5 as the next digit in the result. 
Result so far: 144415.0
Subtracting 3450 from 3968 leaves us with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Advancing to step 9:
690 can be fit into 5180 7 times, resulting in a remainder of 350.
Write down 7 as next digit of the result. 
Result so far: 144415.7
If we subtract 4830 from 5180, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 10:
When dividing 3500 by 690, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 144415.75
Subtracting 3450 from 3500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
If we divide 500 by 690, we get 0 and a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 144415.75
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 12:
5000 divided by 690 is 7 with a remainder of 170.
The number 7 becomes the next digit in our result. 
Result so far: 144415.7507
Subtract 4830 from 5000 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 13:
The number 690 fits into 1700 2 times, leaving a remainder of 320.
The next digit of our result is 2. 
Result so far: 144415.75072
Subtracting 1380 from 1700 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 14:
The number 690 fits into 3200 4 times, leaving a remainder of 440.
Use 4 as the next digit of our solution. 
Result so far: 144415.750724
If we subtract 2760 from 3200, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 15:
4400 divided by 690 is 6 with a remainder of 260.
Write down 6 as next digit of the result. 
Result so far: 144415.7507246
If we take 4140 away from 4400, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 16:
When dividing 2600 by 690, we get 3 with a remainder of 530.
Use 3 as the next digit of our solution. 
Result so far: 144415.75072463
Subtracting 2070 from 2600 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.

In conclusion, the division gives 144415.75072463 with a balance of 5.3e-07.
