We look at the division of 423435 by 72 
We want to divide 423435 by 72.

Advancing to step 1:
If we divide 4 by 72, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 72

Advancing to step 2:
When dividing 42 by 72, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 72

Let's proceed to step 3:
72 goes into 423 5 times with a remainder of 63.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 360 away from 423, we end up with 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 72

Let's proceed to step 4:
634 divided by 72 is 8 with a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Subtracting 576 from 634 leaves us with 58.
Append the next digit (3) from the dividend to 58 and continue with: 583 / 72

Moving on to step 5:
72 goes into 583 8 times with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 588.0
The remainder is 7 after subtracting 576 from 583.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 72

On to step 6:
75 divided by 72 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 5881.0
If we take 72 away from 75, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
72 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 5881.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
300 divided by 72 is 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 5881.04
If we subtract 288 from 300, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
The number 72 fits into 120 1 times, leaving a remainder of 48.
The next digit of our result is 1. 
Result so far: 5881.041
Subtract 72 from 120 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
480 divided by 72 is 6 with a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 5881.0416
Deduct 432 from 480 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
480 divided by 72 is 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 5881.04166
Subtracting 432 from 480 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 5881.04166, and the remainder is 4.8e-05.
