12851920 ÷ 356 
We're looking to find how many times 356 goes into 12851920.

Moving on to step 1:
1 divided by 356 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 356

On to step 2:
356 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 356

Going ahead to step 3:
If we divide 128 by 356, we get 0 and a remainder of 128.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 128 to get 128.
Include the next digit (5) from the dividend after 128, then repeat: 1285 / 356

Step 4:
356 goes into 1285 3 times with a remainder of 217.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 1068 from 1285 leaves us with 217.
Include the next digit (1) from the dividend after 217, then repeat: 2171 / 356

Advancing to step 5:
The number 356 fits into 2171 6 times, leaving a remainder of 35.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
The remainder is 35 after subtracting 2136 from 2171.
Take the next digit (9) from the dividend and append it to 35, then repeat: 359 / 356

Let's proceed to step 6:
When dividing 359 by 356, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 361.0
If we take 356 away from 359, we end up with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 356

On to step 7:
When dividing 32 by 356, we get 0 with a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 3610.0
Subtract 0 from 32 to get 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 356

Moving on to step 8:
356 can be fit into 320 0 times, resulting in a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 36100.0
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 9:
If we divide 3200 by 356, we get 8 and a remainder of 352.
Write down 8 as next digit of the result. 
Result so far: 36100.8
The remainder is 352 after subtracting 2848 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 10:
3520 divided by 356 is 9 with a remainder of 316.
Put 9 as the next digit of the answer. 
Result so far: 36100.89
Subtracting 3204 from 3520 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.

Let's proceed to step 11:
If we divide 3160 by 356, we get 8 and a remainder of 312.
Use 8 as the next digit of our solution. 
Result so far: 36100.898
Subtract 2848 from 3160 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 12:
The number 356 fits into 3120 8 times, leaving a remainder of 272.
The next digit of our result is 8. 
Result so far: 36100.8988
Subtract 2848 from 3120 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

The final result is 36100.8988 with a remainder of 0.00272.
