We look at the division of 30606023 by 420 
Our goal is to divide 30606023 by 420.

Going ahead to step 1:
The number 420 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 420

On to step 2:
When dividing 30 by 420, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 420

Step 3:
306 divided by 420 is 0 with a remainder of 306.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 306, we end up with 306.
Bring next digit (0) of the dividend behind the 306 and repeat the process: 3060 / 420

Moving on to step 4:
3060 divided by 420 is 7 with a remainder of 120.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 2940 from 3060 to get 120.
Include the next digit (6) from the dividend after 120, then repeat: 1206 / 420

Going ahead to step 5:
The number 420 fits into 1206 2 times, leaving a remainder of 366.
The next digit of our result is 2. 
Result so far: 72.0
Subtract 840 from 1206 to get 366.
Include the next digit (0) from the dividend after 366, then repeat: 3660 / 420

Advancing to step 6:
420 can be fit into 3660 8 times, resulting in a remainder of 300.
Record the quotient 8 as the next digit in the result. 
Result so far: 728.0
Subtract 3360 from 3660 to get 300.
Include the next digit (2) from the dividend after 300, then repeat: 3002 / 420

Let's proceed to step 7:
420 can be fit into 3002 7 times, resulting in a remainder of 62.
Use 7 as the next digit of our solution. 
Result so far: 7287.0
Subtracting 2940 from 3002 leaves us with 62.
Fetch the next digit (3) from the dividend, attach it to 62 and continue: 623 / 420

Going ahead to step 8:
420 goes into 623 1 times with a remainder of 203.
Record the quotient 1 as the next digit in the result. 
Result so far: 72871.0
Deduct 420 from 623 and we're left with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Step 9:
When dividing 2030 by 420, we get 4 with a remainder of 350.
The next digit of our result is 4. 
Result so far: 72871.4
If we subtract 1680 from 2030, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 10:
420 can be fit into 3500 8 times, resulting in a remainder of 140.
The next digit of our result is 8. 
Result so far: 72871.48
Subtracting 3360 from 3500 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
If we divide 1400 by 420, we get 3 and a remainder of 140.
The number 3 becomes the next digit in our result. 
Result so far: 72871.483
If we take 1260 away from 1400, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 12:
When dividing 1400 by 420, we get 3 with a remainder of 140.
Record the quotient 3 as the next digit in the result. 
Result so far: 72871.4833
The remainder is 140 after subtracting 1260 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

In conclusion, the division gives 72871.4833 with a balance of 0.0014.
