5 divided by 669 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 669

Advancing to step 2:
669 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Grab the next digit (0) from the dividend, add it to 50, then carry on: 500 / 669

Let's proceed to step 3:
500 divided by 669 is 0 with a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 500 to get 500.
Bring next digit (7) of the dividend behind the 500 and repeat the process: 5007 / 669

Going ahead to step 4:
When dividing 5007 by 669, we get 7 with a remainder of 324.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 4683 away from 5007, we end up with 324.
Fetch the next digit (8) from the dividend, attach it to 324 and continue: 3248 / 669

On to step 5:
If we divide 3248 by 669, we get 4 and a remainder of 572.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Subtracting 2676 from 3248 leaves us with 572.
Bring next digit (5) of the dividend behind the 572 and repeat the process: 5725 / 669

Let's proceed to step 6:
669 can be fit into 5725 8 times, resulting in a remainder of 373.
Record the quotient 8 as the next digit in the result. 
Result so far: 748.0
If we subtract 5352 from 5725, we get 373.
Fetch the next digit (7) from the dividend, attach it to 373 and continue: 3737 / 669

Advancing to step 7:
3737 divided by 669 is 5 with a remainder of 392.
The number 5 becomes the next digit in our result. 
Result so far: 7485.0
Subtract 3345 from 3737 to get 392.
Fetch the next digit (2) from the dividend, attach it to 392 and continue: 3922 / 669

Advancing to step 8:
669 can be fit into 3922 5 times, resulting in a remainder of 577.
The number 5 becomes the next digit in our result. 
Result so far: 74855.0
The remainder is 577 after subtracting 3345 from 3922.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Moving on to step 9:
669 can be fit into 5770 8 times, resulting in a remainder of 418.
The next digit of our result is 8. 
Result so far: 74855.8
If we take 5352 away from 5770, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

On to step 10:
If we divide 4180 by 669, we get 6 and a remainder of 166.
The next digit of our result is 6. 
Result so far: 74855.86
Subtracting 4014 from 4180 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 11:
When dividing 1660 by 669, we get 2 with a remainder of 322.
The number 2 becomes the next digit in our result. 
Result so far: 74855.862
Subtracting 1338 from 1660 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 12:
3220 divided by 669 is 4 with a remainder of 544.
Put 4 as the next digit of the answer. 
Result so far: 74855.8624
The remainder is 544 after subtracting 2676 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Advancing to step 13:
669 can be fit into 5440 8 times, resulting in a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 74855.86248
The remainder is 88 after subtracting 5352 from 5440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 14:
If we divide 880 by 669, we get 1 and a remainder of 211.
The next digit of our result is 1. 
Result so far: 74855.862481
If we subtract 669 from 880, we get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 15:
669 can be fit into 2110 3 times, resulting in a remainder of 103.
Write down 3 as next digit of the result. 
Result so far: 74855.8624813
Subtract 2007 from 2110 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Step 16:
1030 divided by 669 is 1 with a remainder of 361.
Put 1 as the next digit of the answer. 
Result so far: 74855.86248131
The remainder is 361 after subtracting 669 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

After the division, we end up with 74855.86248131 and a remainder of 3.61e-07.
