80378242 ÷ 396 
We're looking to find how many times 396 goes into 80378242.

Advancing to 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
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 396

Advancing to step 2:
If we divide 80 by 396, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Include the next digit (3) from the dividend after 80, then repeat: 803 / 396

Let's proceed to step 3:
396 goes into 803 2 times with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 792 away from 803, we end up with 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 396

On to step 4:
396 can be fit into 117 0 times, resulting in a remainder of 117.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Deduct 0 from 117 and we're left with 117.
Fetch the next digit (8) from the dividend, attach it to 117 and continue: 1178 / 396

Going ahead to step 5:
If we divide 1178 by 396, we get 2 and a remainder of 386.
The next digit of our result is 2. 
Result so far: 202.0
Subtracting 792 from 1178 leaves us with 386.
Fetch the next digit (2) from the dividend, attach it to 386 and continue: 3862 / 396

Going ahead to step 6:
If we divide 3862 by 396, we get 9 and a remainder of 298.
Use 9 as the next digit of our solution. 
Result so far: 2029.0
Subtract 3564 from 3862 to get 298.
Bring next digit (4) of the dividend behind the 298 and repeat the process: 2984 / 396

Moving on to step 7:
If we divide 2984 by 396, we get 7 and a remainder of 212.
The number 7 becomes the next digit in our result. 
Result so far: 20297.0
Subtract 2772 from 2984 to get 212.
Append the next digit (2) from the dividend to 212 and continue with: 2122 / 396

Advancing to step 8:
The number 396 fits into 2122 5 times, leaving a remainder of 142.
The next digit of our result is 5. 
Result so far: 202975.0
Subtracting 1980 from 2122 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 9:
396 can be fit into 1420 3 times, resulting in a remainder of 232.
Write down 3 as next digit of the result. 
Result so far: 202975.3
If we subtract 1188 from 1420, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 10:
When dividing 2320 by 396, we get 5 with a remainder of 340.
Write down 5 as next digit of the result. 
Result so far: 202975.35
Subtract 1980 from 2320 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 11:
3400 divided by 396 is 8 with a remainder of 232.
Use 8 as the next digit of our solution. 
Result so far: 202975.358
Subtracting 3168 from 3400 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 12:
396 can be fit into 2320 5 times, resulting in a remainder of 340.
The next digit of our result is 5. 
Result so far: 202975.3585
Subtracting 1980 from 2320 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 13:
396 goes into 3400 8 times with a remainder of 232.
The next digit of our result is 8. 
Result so far: 202975.35858
Deduct 3168 from 3400 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 14:
If we divide 2320 by 396, we get 5 and a remainder of 340.
The next digit of our result is 5. 
Result so far: 202975.358585
If we subtract 1980 from 2320, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 15:
396 goes into 3400 8 times with a remainder of 232.
Record the quotient 8 as the next digit in the result. 
Result so far: 202975.3585858
If we take 3168 away from 3400, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 16:
The number 396 fits into 2320 5 times, leaving a remainder of 340.
The number 5 becomes the next digit in our result. 
Result so far: 202975.35858585
The remainder is 340 after subtracting 1980 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

After the division, we end up with 202975.35858585 and a remainder of 3.4e-07.
