63121 divided by 30 
We want to figure out the number of times 63121 can be divided by 30.

Moving on to step 1:
The number 30 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 30

Going ahead to step 2:
30 can be fit into 63 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
If we take 60 away from 63, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 30

On to step 3:
The number 30 fits into 31 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 30 from 31, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 30

Going ahead to step 4:
30 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 210.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 30

Let's proceed to step 5:
30 goes into 121 4 times with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 2104.0
Subtracting 120 from 121 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 6:
10 divided by 30 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 2104.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 2104.03
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
30 goes into 100 3 times with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 2104.033
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 2104.033 with a balance of 0.001.
