We look at the division of 210404 by 60 
We're looking to find how many times 60 goes into 210404.

On to step 1:
60 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 60

On to step 2:
60 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 60

On to step 3:
If we divide 210 by 60, we get 3 and a remainder of 30.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 180 from 210 and we're left with 30.
Append the next digit (4) from the dividend to 30 and continue with: 304 / 60

Let's proceed to step 4:
The number 60 fits into 304 5 times, leaving a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 35.0
The remainder is 4 after subtracting 300 from 304.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 60

Moving on to step 5:
60 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 350.0
If we take 0 away from 40, we end up with 40.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 60

Moving on to step 6:
When dividing 404 by 60, we get 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 3506.0
If we take 360 away from 404, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
60 can be fit into 440 7 times, resulting in a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 3506.7
If we take 420 away from 440, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
60 goes into 200 3 times with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 3506.73
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
60 can be fit into 200 3 times, resulting in a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 3506.733
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 3506.733 with a remaining 0.002.
