Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 792 from 1136 to get 344.
Fetch the next digit (6) from the dividend, attach it to 344 and continue: 3446 / 396

Advancing to step 5:
396 can be fit into 3446 8 times, resulting in a remainder of 278.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
If we subtract 3168 from 3446, we get 278.
Grab the next digit (8) from the dividend, add it to 278, then carry on: 2788 / 396

Step 6:
396 can be fit into 2788 7 times, resulting in a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 1287.0
Subtracting 2772 from 2788 leaves us with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 396

Moving on to step 7:
If we divide 169 by 396, we get 0 and a remainder of 169.
The next digit of our result is 0. 
Result so far: 12870.0
The remainder is 169 after subtracting 0 from 169.
Fetch the next digit (7) from the dividend, attach it to 169 and continue: 1697 / 396

Moving on to step 8:
1697 divided by 396 is 4 with a remainder of 113.
Write down 4 as next digit of the result. 
Result so far: 128704.0
If we take 1584 away from 1697, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Advancing to step 9:
When dividing 1130 by 396, we get 2 with a remainder of 338.
Write down 2 as next digit of the result. 
Result so far: 128704.2
Subtract 792 from 1130 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Step 10:
3380 divided by 396 is 8 with a remainder of 212.
Use 8 as the next digit of our solution. 
Result so far: 128704.28
If we take 3168 away from 3380, we end up 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.

Advancing to step 11:
When dividing 2120 by 396, we get 5 with a remainder of 140.
The next digit of our result is 5. 
Result so far: 128704.285
If we subtract 1980 from 2120, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 12:
396 can be fit into 1400 3 times, resulting in a remainder of 212.
Record the quotient 3 as the next digit in the result. 
Result so far: 128704.2853
Deduct 1188 from 1400 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.

Advancing to step 13:
The number 396 fits into 2120 5 times, leaving a remainder of 140.
The next digit of our result is 5. 
Result so far: 128704.28535
If we take 1980 away from 2120, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 14:
The number 396 fits into 1400 3 times, leaving a remainder of 212.
Use 3 as the next digit of our solution. 
Result so far: 128704.285353
The remainder is 212 after subtracting 1188 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 15:
2120 divided by 396 is 5 with a remainder of 140.
Put 5 as the next digit of the answer. 
Result so far: 128704.2853535
If we take 1980 away from 2120, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 16:
When dividing 1400 by 396, we get 3 with a remainder of 212.
The number 3 becomes the next digit in our result. 
Result so far: 128704.28535353
If we subtract 1188 from 1400, 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.
