Let's divide 1478238 by 669
We're looking to find how many times 669 goes into 1478238.

Step 1:
The number 669 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 669

Moving on to step 2:
If we divide 14 by 669, we get 0 and a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Bring next digit (7) of the dividend behind the 14 and repeat the process: 147 / 669

Moving on to step 3:
The number 669 fits into 147 0 times, leaving a remainder of 147.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 147, we end up with 147.
Take the next digit (8) from the dividend and append it to 147, then repeat: 1478 / 669

Going ahead to step 4:
669 goes into 1478 2 times with a remainder of 140.
The next digit of our result is 2. 
Result so far: 2.0
If we take 1338 away from 1478, we end up with 140.
Append the next digit (2) from the dividend to 140 and continue with: 1402 / 669

Moving on to step 5:
669 can be fit into 1402 2 times, resulting in a remainder of 64.
The next digit of our result is 2. 
Result so far: 22.0
If we subtract 1338 from 1402, we get 64.
Take the next digit (3) from the dividend and append it to 64, then repeat: 643 / 669

On to step 6:
When dividing 643 by 669, we get 0 with a remainder of 643.
Put 0 as the next digit of the answer. 
Result so far: 220.0
The remainder is 643 after subtracting 0 from 643.
Include the next digit (8) from the dividend after 643, then repeat: 6438 / 669

Moving on to step 7:
When dividing 6438 by 669, we get 9 with a remainder of 417.
Put 9 as the next digit of the answer. 
Result so far: 2209.0
Subtract 6021 from 6438 to get 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

On to step 8:
When dividing 4170 by 669, we get 6 with a remainder of 156.
Write down 6 as next digit of the result. 
Result so far: 2209.6
Subtract 4014 from 4170 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 9:
669 can be fit into 1560 2 times, resulting in a remainder of 222.
Use 2 as the next digit of our solution. 
Result so far: 2209.62
Deduct 1338 from 1560 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 10:
If we divide 2220 by 669, we get 3 and a remainder of 213.
Record the quotient 3 as the next digit in the result. 
Result so far: 2209.623
Subtracting 2007 from 2220 leaves us with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Moving on to step 11:
If we divide 2130 by 669, we get 3 and a remainder of 123.
The number 3 becomes the next digit in our result. 
Result so far: 2209.6233
If we take 2007 away from 2130, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

The quotient of the division is 2209.6233, and the remainder is 0.00123.
