We look at the division of 12471121 by 396 
We want to figure out the number of times 12471121 can be divided by 396.

Moving on to step 1:
396 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 396

Let's proceed to step 2:
The number 396 fits into 12 0 times, leaving a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 396

Step 3:
124 divided by 396 is 0 with a remainder of 124.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 124 and we're left with 124.
Include the next digit (7) from the dividend after 124, then repeat: 1247 / 396

On to step 4:
396 can be fit into 1247 3 times, resulting in a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 1188 from 1247, we get 59.
Take the next digit (1) from the dividend and append it to 59, then repeat: 591 / 396

Moving on to step 5:
If we divide 591 by 396, we get 1 and a remainder of 195.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we take 396 away from 591, we end up with 195.
Fetch the next digit (1) from the dividend, attach it to 195 and continue: 1951 / 396

Let's proceed to step 6:
If we divide 1951 by 396, we get 4 and a remainder of 367.
Record the quotient 4 as the next digit in the result. 
Result so far: 314.0
Deduct 1584 from 1951 and we're left with 367.
Take the next digit (2) from the dividend and append it to 367, then repeat: 3672 / 396

Advancing to step 7:
396 can be fit into 3672 9 times, resulting in a remainder of 108.
The number 9 becomes the next digit in our result. 
Result so far: 3149.0
If we subtract 3564 from 3672, we get 108.
Fetch the next digit (1) from the dividend, attach it to 108 and continue: 1081 / 396

Going ahead to step 8:
396 can be fit into 1081 2 times, resulting in a remainder of 289.
The number 2 becomes the next digit in our result. 
Result so far: 31492.0
The remainder is 289 after subtracting 792 from 1081.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

On to step 9:
The number 396 fits into 2890 7 times, leaving a remainder of 118.
The number 7 becomes the next digit in our result. 
Result so far: 31492.7
Subtracting 2772 from 2890 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 10:
1180 divided by 396 is 2 with a remainder of 388.
Write down 2 as next digit of the result. 
Result so far: 31492.72
Deduct 792 from 1180 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 11:
3880 divided by 396 is 9 with a remainder of 316.
Write down 9 as next digit of the result. 
Result so far: 31492.729
If we subtract 3564 from 3880, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 12:
396 goes into 3160 7 times with a remainder of 388.
The number 7 becomes the next digit in our result. 
Result so far: 31492.7297
Subtract 2772 from 3160 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

On to step 13:
The number 396 fits into 3880 9 times, leaving a remainder of 316.
Put 9 as the next digit of the answer. 
Result so far: 31492.72979
Deduct 3564 from 3880 and we're left with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Moving on to step 14:
When dividing 3160 by 396, we get 7 with a remainder of 388.
Record the quotient 7 as the next digit in the result. 
Result so far: 31492.729797
Deduct 2772 from 3160 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 15:
The number 396 fits into 3880 9 times, leaving a remainder of 316.
Record the quotient 9 as the next digit in the result. 
Result so far: 31492.7297979
Subtracting 3564 from 3880 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 16:
396 goes into 3160 7 times with a remainder of 388.
Write down 7 as next digit of the result. 
Result so far: 31492.72979797
The remainder is 388 after subtracting 2772 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

The final outcome is 31492.72979797, with a leftover of 3.88e-07.
