Let's divide 56980609 by 669
We want to figure out the number of times 56980609 can be divided by 669.

Going ahead to step 1:
If we divide 5 by 669, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 669

Moving on to step 2:
669 goes into 56 0 times with a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 56 to get 56.
Fetch the next digit (9) from the dividend, attach it to 56 and continue: 569 / 669

Going ahead to step 3:
If we divide 569 by 669, we get 0 and a remainder of 569.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 569 to get 569.
Take the next digit (8) from the dividend and append it to 569, then repeat: 5698 / 669

Moving on to step 4:
669 can be fit into 5698 8 times, resulting in a remainder of 346.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 5352 from 5698 and we're left with 346.
Take the next digit (0) from the dividend and append it to 346, then repeat: 3460 / 669

Step 5:
The number 669 fits into 3460 5 times, leaving a remainder of 115.
Use 5 as the next digit of our solution. 
Result so far: 85.0
If we take 3345 away from 3460, we end up with 115.
Include the next digit (6) from the dividend after 115, then repeat: 1156 / 669

Going ahead to step 6:
When dividing 1156 by 669, we get 1 with a remainder of 487.
Use 1 as the next digit of our solution. 
Result so far: 851.0
If we take 669 away from 1156, we end up with 487.
Take the next digit (0) from the dividend and append it to 487, then repeat: 4870 / 669

Moving on to step 7:
The number 669 fits into 4870 7 times, leaving a remainder of 187.
Record the quotient 7 as the next digit in the result. 
Result so far: 8517.0
Deduct 4683 from 4870 and we're left with 187.
Bring next digit (9) of the dividend behind the 187 and repeat the process: 1879 / 669

Step 8:
669 can be fit into 1879 2 times, resulting in a remainder of 541.
The number 2 becomes the next digit in our result. 
Result so far: 85172.0
If we take 1338 away from 1879, we end up with 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Let's proceed to step 9:
669 can be fit into 5410 8 times, resulting in a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 85172.8
Deduct 5352 from 5410 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 10:
If we divide 580 by 669, we get 0 and a remainder of 580.
Use 0 as the next digit of our solution. 
Result so far: 85172.8
If we take 0 away from 580, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 11:
If we divide 5800 by 669, we get 8 and a remainder of 448.
Put 8 as the next digit of the answer. 
Result so far: 85172.808
The remainder is 448 after subtracting 5352 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 12:
The number 669 fits into 4480 6 times, leaving a remainder of 466.
Write down 6 as next digit of the result. 
Result so far: 85172.8086
Subtract 4014 from 4480 to get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Step 13:
The number 669 fits into 4660 6 times, leaving a remainder of 646.
Use 6 as the next digit of our solution. 
Result so far: 85172.80866
Subtracting 4014 from 4660 leaves us with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

In conclusion, the division gives 85172.80866 with a balance of 0.000646.
