Let's divide 13905980 by 600
We want to figure out the number of times 13905980 can be divided by 600.

Step 1:
The number 600 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 600

Step 2:
600 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 600

On to step 3:
When dividing 139 by 600, we get 0 with a remainder of 139.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 139 leaves us with 139.
Append the next digit (0) from the dividend to 139 and continue with: 1390 / 600

Step 4:
1390 divided by 600 is 2 with a remainder of 190.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1200 from 1390 leaves us with 190.
Include the next digit (5) from the dividend after 190, then repeat: 1905 / 600

Moving on to step 5:
When dividing 1905 by 600, we get 3 with a remainder of 105.
Put 3 as the next digit of the answer. 
Result so far: 23.0
The remainder is 105 after subtracting 1800 from 1905.
Include the next digit (9) from the dividend after 105, then repeat: 1059 / 600

On to step 6:
600 goes into 1059 1 times with a remainder of 459.
Use 1 as the next digit of our solution. 
Result so far: 231.0
The remainder is 459 after subtracting 600 from 1059.
Grab the next digit (8) from the dividend, add it to 459, then carry on: 4598 / 600

Advancing to step 7:
4598 divided by 600 is 7 with a remainder of 398.
Record the quotient 7 as the next digit in the result. 
Result so far: 2317.0
Subtract 4200 from 4598 to get 398.
Bring next digit (0) of the dividend behind the 398 and repeat the process: 3980 / 600

Going ahead to step 8:
600 goes into 3980 6 times with a remainder of 380.
The number 6 becomes the next digit in our result. 
Result so far: 23176.0
If we take 3600 away from 3980, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 9:
3800 divided by 600 is 6 with a remainder of 200.
Record the quotient 6 as the next digit in the result. 
Result so far: 23176.6
The remainder is 200 after subtracting 3600 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 10:
600 can be fit into 2000 3 times, resulting in a remainder of 200.
Use 3 as the next digit of our solution. 
Result so far: 23176.63
If we take 1800 away from 2000, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 11:
When dividing 2000 by 600, we get 3 with a remainder of 200.
The next digit of our result is 3. 
Result so far: 23176.633
Deduct 1800 from 2000 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 23176.633 with a remainder of 0.02.
