Let's divide 12054407 by 669
Our goal is to divide 12054407 by 669.

Going ahead to step 1:
669 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 669

Moving on to step 2:
12 divided by 669 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 669

Moving on to step 3:
The number 669 fits into 120 0 times, leaving a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 120 leaves us with 120.
Take the next digit (5) from the dividend and append it to 120, then repeat: 1205 / 669

Let's proceed to step 4:
If we divide 1205 by 669, we get 1 and a remainder of 536.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 669 from 1205 to get 536.
Take the next digit (4) from the dividend and append it to 536, then repeat: 5364 / 669

Advancing to step 5:
The number 669 fits into 5364 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 12 after subtracting 5352 from 5364.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 669

On to step 6:
124 divided by 669 is 0 with a remainder of 124.
Write down 0 as next digit of the result. 
Result so far: 180.0
Subtracting 0 from 124 leaves us with 124.
Grab the next digit (0) from the dividend, add it to 124, then carry on: 1240 / 669

Moving on to step 7:
1240 divided by 669 is 1 with a remainder of 571.
Put 1 as the next digit of the answer. 
Result so far: 1801.0
The remainder is 571 after subtracting 669 from 1240.
Grab the next digit (7) from the dividend, add it to 571, then carry on: 5717 / 669

Moving on to step 8:
The number 669 fits into 5717 8 times, leaving a remainder of 365.
Put 8 as the next digit of the answer. 
Result so far: 18018.0
The remainder is 365 after subtracting 5352 from 5717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 9:
When dividing 3650 by 669, we get 5 with a remainder of 305.
The next digit of our result is 5. 
Result so far: 18018.5
Subtracting 3345 from 3650 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 10:
If we divide 3050 by 669, we get 4 and a remainder of 374.
Write down 4 as next digit of the result. 
Result so far: 18018.54
If we subtract 2676 from 3050, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Advancing to step 11:
The number 669 fits into 3740 5 times, leaving a remainder of 395.
Put 5 as the next digit of the answer. 
Result so far: 18018.545
If we subtract 3345 from 3740, we get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Advancing to step 12:
When dividing 3950 by 669, we get 5 with a remainder of 605.
The number 5 becomes the next digit in our result. 
Result so far: 18018.5455
The remainder is 605 after subtracting 3345 from 3950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

In conclusion, the division gives 18018.5455 with a balance of 0.00605.
