We're dividing 12921204 by 404 
We're looking to find how many times 404 goes into 12921204.

Step 1:
404 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 404

On to step 2:
12 divided by 404 is 0 with 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 (9) from the dividend to 12 and continue with: 129 / 404

Step 3:
If we divide 129 by 404, we get 0 and a remainder of 129.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 129 leaves us with 129.
Fetch the next digit (2) from the dividend, attach it to 129 and continue: 1292 / 404

Advancing to step 4:
404 can be fit into 1292 3 times, resulting in a remainder of 80.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 80 after subtracting 1212 from 1292.
Grab the next digit (1) from the dividend, add it to 80, then carry on: 801 / 404

Let's proceed to step 5:
404 goes into 801 1 times with a remainder of 397.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 404 from 801 to get 397.
Fetch the next digit (2) from the dividend, attach it to 397 and continue: 3972 / 404

Step 6:
3972 divided by 404 is 9 with a remainder of 336.
The next digit of our result is 9. 
Result so far: 319.0
If we take 3636 away from 3972, we end up with 336.
Bring next digit (0) of the dividend behind the 336 and repeat the process: 3360 / 404

Let's proceed to step 7:
When dividing 3360 by 404, we get 8 with a remainder of 128.
Put 8 as the next digit of the answer. 
Result so far: 3198.0
Subtract 3232 from 3360 to get 128.
Append the next digit (4) from the dividend to 128 and continue with: 1284 / 404

Going ahead to step 8:
If we divide 1284 by 404, we get 3 and a remainder of 72.
The next digit of our result is 3. 
Result so far: 31983.0
Subtract 1212 from 1284 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
If we divide 720 by 404, we get 1 and a remainder of 316.
Use 1 as the next digit of our solution. 
Result so far: 31983.1
Subtracting 404 from 720 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 10:
The number 404 fits into 3160 7 times, leaving a remainder of 332.
Put 7 as the next digit of the answer. 
Result so far: 31983.17
Deduct 2828 from 3160 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 11:
3320 divided by 404 is 8 with a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 31983.178
If we take 3232 away from 3320, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 12:
880 divided by 404 is 2 with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 31983.1782
If we take 808 away from 880, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 13:
If we divide 720 by 404, we get 1 and a remainder of 316.
The number 1 becomes the next digit in our result. 
Result so far: 31983.17821
Subtract 404 from 720 to 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 14:
404 can be fit into 3160 7 times, resulting in a remainder of 332.
The number 7 becomes the next digit in our result. 
Result so far: 31983.178217
Deduct 2828 from 3160 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 15:
When dividing 3320 by 404, we get 8 with a remainder of 88.
The number 8 becomes the next digit in our result. 
Result so far: 31983.1782178
The remainder is 88 after subtracting 3232 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 16:
404 goes into 880 2 times with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 31983.17821782
The remainder is 72 after subtracting 808 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 31983.17821782 and a remainder of 7.2e-08.
