55458429 divided by 669 
Our goal is to divide 55458429 by 669.

Step 1:
669 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 669

Step 2:
55 divided by 669 is 0 with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Include the next digit (4) from the dividend after 55, then repeat: 554 / 669

Moving on to step 3:
554 divided by 669 is 0 with a remainder of 554.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 554, we get 554.
Fetch the next digit (5) from the dividend, attach it to 554 and continue: 5545 / 669

On to step 4:
5545 divided by 669 is 8 with a remainder of 193.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 193 after subtracting 5352 from 5545.
Append the next digit (8) from the dividend to 193 and continue with: 1938 / 669

On to step 5:
669 can be fit into 1938 2 times, resulting in a remainder of 600.
Write down 2 as next digit of the result. 
Result so far: 82.0
Subtracting 1338 from 1938 leaves us with 600.
Append the next digit (4) from the dividend to 600 and continue with: 6004 / 669

Advancing to step 6:
If we divide 6004 by 669, we get 8 and a remainder of 652.
The next digit of our result is 8. 
Result so far: 828.0
If we subtract 5352 from 6004, we get 652.
Take the next digit (2) from the dividend and append it to 652, then repeat: 6522 / 669

Advancing to step 7:
If we divide 6522 by 669, we get 9 and a remainder of 501.
The next digit of our result is 9. 
Result so far: 8289.0
Subtract 6021 from 6522 to get 501.
Append the next digit (9) from the dividend to 501 and continue with: 5019 / 669

On to step 8:
669 can be fit into 5019 7 times, resulting in a remainder of 336.
Write down 7 as next digit of the result. 
Result so far: 82897.0
Deduct 4683 from 5019 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 9:
3360 divided by 669 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 82897.5
The remainder is 15 after subtracting 3345 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
150 divided by 669 is 0 with a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 82897.5
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 11:
669 can be fit into 1500 2 times, resulting in a remainder of 162.
Put 2 as the next digit of the answer. 
Result so far: 82897.502
The remainder is 162 after subtracting 1338 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 12:
The number 669 fits into 1620 2 times, leaving a remainder of 282.
The number 2 becomes the next digit in our result. 
Result so far: 82897.5022
Subtracting 1338 from 1620 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

After the division, we end up with 82897.5022 and a remainder of 0.00282.
