We look at the division of 422972 by 3 
We're looking to find how many times 3 goes into 422972.

Step 1:
3 can be fit into 4 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 3 from 4 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 3

Let's proceed to step 2:
The number 3 fits into 12 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 12 from 12 and we're left with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 3

Step 3:
3 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 140.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 3

Going ahead to step 4:
The number 3 fits into 29 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 1409.0
If we subtract 27 from 29, we get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 3

On to step 5:
The number 3 fits into 27 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 14099.0
If we subtract 27 from 27, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 3

Step 6:
3 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 140990.0
If we subtract 0 from 2, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 140990.6
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 140990.66
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 140990.66 with a balance of 0.002.
