18509285 ÷ 669 
Let's see how many times 669 fits into 18509285.

On to step 1:
669 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 669

On to step 2:
If we divide 18 by 669, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 669

Moving on to step 3:
669 can be fit into 185 0 times, resulting in a remainder of 185.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 185 and we're left with 185.
Grab the next digit (0) from the dividend, add it to 185, then carry on: 1850 / 669

Let's proceed to step 4:
The number 669 fits into 1850 2 times, leaving a remainder of 512.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1338 from 1850 and we're left with 512.
Append the next digit (9) from the dividend to 512 and continue with: 5129 / 669

Step 5:
5129 divided by 669 is 7 with a remainder of 446.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
The remainder is 446 after subtracting 4683 from 5129.
Append the next digit (2) from the dividend to 446 and continue with: 4462 / 669

Moving on to step 6:
If we divide 4462 by 669, we get 6 and a remainder of 448.
The next digit of our result is 6. 
Result so far: 276.0
Subtract 4014 from 4462 to get 448.
Grab the next digit (8) from the dividend, add it to 448, then carry on: 4488 / 669

Step 7:
When dividing 4488 by 669, we get 6 with a remainder of 474.
Record the quotient 6 as the next digit in the result. 
Result so far: 2766.0
If we subtract 4014 from 4488, we get 474.
Take the next digit (5) from the dividend and append it to 474, then repeat: 4745 / 669

On to step 8:
669 can be fit into 4745 7 times, resulting in a remainder of 62.
The number 7 becomes the next digit in our result. 
Result so far: 27667.0
Subtracting 4683 from 4745 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 9:
When dividing 620 by 669, we get 0 with a remainder of 620.
Record the quotient 0 as the next digit in the result. 
Result so far: 27667.0
Subtract 0 from 620 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

On to step 10:
When dividing 6200 by 669, we get 9 with a remainder of 179.
Put 9 as the next digit of the answer. 
Result so far: 27667.09
The remainder is 179 after subtracting 6021 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

On to step 11:
669 can be fit into 1790 2 times, resulting in a remainder of 452.
Record the quotient 2 as the next digit in the result. 
Result so far: 27667.092
If we take 1338 away from 1790, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Let's proceed to step 12:
4520 divided by 669 is 6 with a remainder of 506.
Record the quotient 6 as the next digit in the result. 
Result so far: 27667.0926
The remainder is 506 after subtracting 4014 from 4520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Going ahead to step 13:
The number 669 fits into 5060 7 times, leaving a remainder of 377.
Write down 7 as next digit of the result. 
Result so far: 27667.09267
Subtracting 4683 from 5060 leaves us with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Moving on to step 14:
When dividing 3770 by 669, we get 5 with a remainder of 425.
Write down 5 as next digit of the result. 
Result so far: 27667.092675
Deduct 3345 from 3770 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Going ahead to step 15:
669 can be fit into 4250 6 times, resulting in a remainder of 236.
Record the quotient 6 as the next digit in the result. 
Result so far: 27667.0926756
Subtract 4014 from 4250 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 16:
If we divide 2360 by 669, we get 3 and a remainder of 353.
Record the quotient 3 as the next digit in the result. 
Result so far: 27667.09267563
If we take 2007 away from 2360, we end up with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

The final result is 27667.09267563 with a remainder of 3.53e-07.
