89990731 ÷ 396 
We're looking to find how many times 396 goes into 89990731.

Step 1:
8 divided by 396 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 396

Step 2:
If we divide 89 by 396, we get 0 and a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Append the next digit (9) from the dividend to 89 and continue with: 899 / 396

On to step 3:
899 divided by 396 is 2 with a remainder of 107.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 107 after subtracting 792 from 899.
Include the next digit (9) from the dividend after 107, then repeat: 1079 / 396

Moving on to step 4:
396 can be fit into 1079 2 times, resulting in a remainder of 287.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 792 from 1079 to get 287.
Fetch the next digit (0) from the dividend, attach it to 287 and continue: 2870 / 396

Step 5:
2870 divided by 396 is 7 with a remainder of 98.
Record the quotient 7 as the next digit in the result. 
Result so far: 227.0
If we take 2772 away from 2870, we end up with 98.
Include the next digit (7) from the dividend after 98, then repeat: 987 / 396

Moving on to step 6:
987 divided by 396 is 2 with a remainder of 195.
The next digit of our result is 2. 
Result so far: 2272.0
The remainder is 195 after subtracting 792 from 987.
Grab the next digit (3) from the dividend, add it to 195, then carry on: 1953 / 396

Going ahead to step 7:
If we divide 1953 by 396, we get 4 and a remainder of 369.
Put 4 as the next digit of the answer. 
Result so far: 22724.0
Subtract 1584 from 1953 to get 369.
Bring next digit (1) of the dividend behind the 369 and repeat the process: 3691 / 396

Moving on to step 8:
396 goes into 3691 9 times with a remainder of 127.
Record the quotient 9 as the next digit in the result. 
Result so far: 227249.0
Subtracting 3564 from 3691 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Let's proceed to step 9:
When dividing 1270 by 396, we get 3 with a remainder of 82.
Write down 3 as next digit of the result. 
Result so far: 227249.3
The remainder is 82 after subtracting 1188 from 1270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 10:
If we divide 820 by 396, we get 2 and a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 227249.32
Subtracting 792 from 820 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
When dividing 280 by 396, we get 0 with a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 227249.32
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 12:
If we divide 2800 by 396, we get 7 and a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 227249.3207
The remainder is 28 after subtracting 2772 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 13:
396 goes into 280 0 times with a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 227249.3207
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 14:
396 can be fit into 2800 7 times, resulting in a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 227249.320707
The remainder is 28 after subtracting 2772 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 15:
280 divided by 396 is 0 with a remainder of 280.
The next digit of our result is 0. 
Result so far: 227249.320707
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 16:
396 goes into 2800 7 times with a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 227249.32070707
If we take 2772 away from 2800, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 227249.32070707 and a remainder of 2.8e-08.
