Let's divide 52306870 by 420
We're looking to find how many times 420 goes into 52306870.

Advancing to step 1:
420 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 420

Step 2:
If we divide 52 by 420, we get 0 and a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Bring next digit (3) of the dividend behind the 52 and repeat the process: 523 / 420

Let's proceed to step 3:
The number 420 fits into 523 1 times, leaving a remainder of 103.
The next digit of our result is 1. 
Result so far: 1.0
If we take 420 away from 523, we end up with 103.
Take the next digit (0) from the dividend and append it to 103, then repeat: 1030 / 420

On to step 4:
If we divide 1030 by 420, we get 2 and a remainder of 190.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 190 after subtracting 840 from 1030.
Grab the next digit (6) from the dividend, add it to 190, then carry on: 1906 / 420

Moving on to step 5:
420 goes into 1906 4 times with a remainder of 226.
Put 4 as the next digit of the answer. 
Result so far: 124.0
If we subtract 1680 from 1906, we get 226.
Append the next digit (8) from the dividend to 226 and continue with: 2268 / 420

Moving on to step 6:
If we divide 2268 by 420, we get 5 and a remainder of 168.
The next digit of our result is 5. 
Result so far: 1245.0
If we take 2100 away from 2268, we end up with 168.
Bring next digit (7) of the dividend behind the 168 and repeat the process: 1687 / 420

On to step 7:
If we divide 1687 by 420, we get 4 and a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 12454.0
Deduct 1680 from 1687 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 420

Let's proceed to step 8:
420 can be fit into 70 0 times, resulting in a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 124540.0
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
If we divide 700 by 420, we get 1 and a remainder of 280.
Use 1 as the next digit of our solution. 
Result so far: 124540.1
The remainder is 280 after subtracting 420 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 10:
If we divide 2800 by 420, we get 6 and a remainder of 280.
Write down 6 as next digit of the result. 
Result so far: 124540.16
Subtract 2520 from 2800 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 11:
420 goes into 2800 6 times with a remainder of 280.
The number 6 becomes the next digit in our result. 
Result so far: 124540.166
If we subtract 2520 from 2800, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

In conclusion, the division gives 124540.166 with a balance of 0.028.
