421306 ÷ 50 
Our goal is to divide 421306 by 50.

Advancing to step 1:
50 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 50

Advancing to step 2:
42 divided by 50 is 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 50

Advancing to step 3:
If we divide 421 by 50, we get 8 and a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 400 from 421 to get 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 50

Let's proceed to step 4:
50 goes into 213 4 times with a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
Subtract 200 from 213 to get 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 50

Moving on to step 5:
50 goes into 130 2 times with a remainder of 30.
The next digit of our result is 2. 
Result so far: 842.0
If we take 100 away from 130, we end up with 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 50

On to step 6:
When dividing 306 by 50, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 8426.0
If we subtract 300 from 306, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
If we divide 60 by 50, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 8426.1
If we subtract 50 from 60, 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 8:
The number 50 fits into 100 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 8426.12
If we subtract 100 from 100, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
0 divided by 50 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8426.12
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
The number 50 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8426.12
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 8426.12 with a balance of 0.0.
