99690943 ÷ 145 
Let's see how many times 145 fits into 99690943.

Let's proceed to step 1:
When dividing 9 by 145, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 145

On to step 2:
99 divided by 145 is 0 with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Bring next digit (6) of the dividend behind the 99 and repeat the process: 996 / 145

Going ahead to step 3:
If we divide 996 by 145, we get 6 and a remainder of 126.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 126 after subtracting 870 from 996.
Take the next digit (9) from the dividend and append it to 126, then repeat: 1269 / 145

Step 4:
145 can be fit into 1269 8 times, resulting in a remainder of 109.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Subtracting 1160 from 1269 leaves us with 109.
Take the next digit (0) from the dividend and append it to 109, then repeat: 1090 / 145

Advancing to step 5:
The number 145 fits into 1090 7 times, leaving a remainder of 75.
Record the quotient 7 as the next digit in the result. 
Result so far: 687.0
The remainder is 75 after subtracting 1015 from 1090.
Take the next digit (9) from the dividend and append it to 75, then repeat: 759 / 145

Moving on to step 6:
145 can be fit into 759 5 times, resulting in a remainder of 34.
Use 5 as the next digit of our solution. 
Result so far: 6875.0
If we subtract 725 from 759, we get 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 145

Let's proceed to step 7:
344 divided by 145 is 2 with a remainder of 54.
Put 2 as the next digit of the answer. 
Result so far: 68752.0
Deduct 290 from 344 and we're left with 54.
Grab the next digit (3) from the dividend, add it to 54, then carry on: 543 / 145

Moving on to step 8:
The number 145 fits into 543 3 times, leaving a remainder of 108.
The number 3 becomes the next digit in our result. 
Result so far: 687523.0
If we subtract 435 from 543, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 9:
145 can be fit into 1080 7 times, resulting in a remainder of 65.
The number 7 becomes the next digit in our result. 
Result so far: 687523.7
The remainder is 65 after subtracting 1015 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 10:
The number 145 fits into 650 4 times, leaving a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 687523.74
The remainder is 70 after subtracting 580 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 11:
700 divided by 145 is 4 with a remainder of 120.
Put 4 as the next digit of the answer. 
Result so far: 687523.744
Subtracting 580 from 700 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 687523.744 and a remainder of 0.012.
