12885845 divided by 604 
Let's see how many times 604 fits into 12885845.

Step 1:
604 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 604

Going ahead to step 2:
604 goes into 12 0 times with 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.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 604

Let's proceed to step 3:
The number 604 fits into 128 0 times, leaving a remainder of 128.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 128, we get 128.
Append the next digit (8) from the dividend to 128 and continue with: 1288 / 604

Let's proceed to step 4:
When dividing 1288 by 604, we get 2 with a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1208 from 1288 leaves us with 80.
Fetch the next digit (5) from the dividend, attach it to 80 and continue: 805 / 604

Step 5:
If we divide 805 by 604, we get 1 and a remainder of 201.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 604 away from 805, we end up with 201.
Fetch the next digit (8) from the dividend, attach it to 201 and continue: 2018 / 604

Advancing to step 6:
The number 604 fits into 2018 3 times, leaving a remainder of 206.
The next digit of our result is 3. 
Result so far: 213.0
Deduct 1812 from 2018 and we're left with 206.
Fetch the next digit (4) from the dividend, attach it to 206 and continue: 2064 / 604

On to step 7:
When dividing 2064 by 604, we get 3 with a remainder of 252.
Put 3 as the next digit of the answer. 
Result so far: 2133.0
Subtracting 1812 from 2064 leaves us with 252.
Grab the next digit (5) from the dividend, add it to 252, then carry on: 2525 / 604

Let's proceed to step 8:
If we divide 2525 by 604, we get 4 and a remainder of 109.
The next digit of our result is 4. 
Result so far: 21334.0
Deduct 2416 from 2525 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Let's proceed to step 9:
When dividing 1090 by 604, we get 1 with a remainder of 486.
Record the quotient 1 as the next digit in the result. 
Result so far: 21334.1
Subtracting 604 from 1090 leaves us with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Step 10:
604 can be fit into 4860 8 times, resulting in a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 21334.18
Subtracting 4832 from 4860 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
If we divide 280 by 604, we get 0 and a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 21334.18
The remainder is 280 after subtracting 0 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 12:
When dividing 2800 by 604, we get 4 with a remainder of 384.
Record the quotient 4 as the next digit in the result. 
Result so far: 21334.1804
Subtract 2416 from 2800 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 13:
604 can be fit into 3840 6 times, resulting in a remainder of 216.
The next digit of our result is 6. 
Result so far: 21334.18046
Subtract 3624 from 3840 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 14:
If we divide 2160 by 604, we get 3 and a remainder of 348.
Put 3 as the next digit of the answer. 
Result so far: 21334.180463
Deduct 1812 from 2160 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 15:
604 can be fit into 3480 5 times, resulting in a remainder of 460.
Use 5 as the next digit of our solution. 
Result so far: 21334.1804635
Subtracting 3020 from 3480 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 16:
When dividing 4600 by 604, we get 7 with a remainder of 372.
Put 7 as the next digit of the answer. 
Result so far: 21334.18046357
Subtracting 4228 from 4600 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

After the division, we end up with 21334.18046357 and a remainder of 3.72e-07.
