We divide 12880253 by 392
We want to divide 12880253 by 392.

Advancing to step 1:
If we divide 1 by 392, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 392

Advancing to step 2:
If we divide 12 by 392, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 392

Going ahead to step 3:
If we divide 128 by 392, we get 0 and a remainder of 128.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 128 to get 128.
Grab the next digit (8) from the dividend, add it to 128, then carry on: 1288 / 392

Step 4:
The number 392 fits into 1288 3 times, leaving a remainder of 112.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 1176 from 1288 to get 112.
Grab the next digit (0) from the dividend, add it to 112, then carry on: 1120 / 392

Going ahead to step 5:
The number 392 fits into 1120 2 times, leaving a remainder of 336.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Deduct 784 from 1120 and we're left with 336.
Grab the next digit (2) from the dividend, add it to 336, then carry on: 3362 / 392

Advancing to step 6:
When dividing 3362 by 392, we get 8 with a remainder of 226.
Use 8 as the next digit of our solution. 
Result so far: 328.0
If we take 3136 away from 3362, we end up with 226.
Append the next digit (5) from the dividend to 226 and continue with: 2265 / 392

Going ahead to step 7:
392 goes into 2265 5 times with a remainder of 305.
Record the quotient 5 as the next digit in the result. 
Result so far: 3285.0
Deduct 1960 from 2265 and we're left with 305.
Grab the next digit (3) from the dividend, add it to 305, then carry on: 3053 / 392

Let's proceed to step 8:
If we divide 3053 by 392, we get 7 and a remainder of 309.
Record the quotient 7 as the next digit in the result. 
Result so far: 32857.0
Subtract 2744 from 3053 to get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Moving on to step 9:
The number 392 fits into 3090 7 times, leaving a remainder of 346.
Write down 7 as next digit of the result. 
Result so far: 32857.7
If we take 2744 away from 3090, we end up with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Advancing to step 10:
The number 392 fits into 3460 8 times, leaving a remainder of 324.
Record the quotient 8 as the next digit in the result. 
Result so far: 32857.78
If we subtract 3136 from 3460, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 11:
3240 divided by 392 is 8 with a remainder of 104.
The next digit of our result is 8. 
Result so far: 32857.788
If we take 3136 away from 3240, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

After the division, we end up with 32857.788 and a remainder of 0.0104.
