We're dividing 420957 by 72 
Our goal is to divide 420957 by 72.

Let's proceed to step 1:
72 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 72

Let's proceed to step 2:
If we divide 42 by 72, we get 0 and a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 72

Advancing to step 3:
The number 72 fits into 420 5 times, leaving a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 360 from 420 to get 60.
Fetch the next digit (9) from the dividend, attach it to 60 and continue: 609 / 72

Going ahead to step 4:
If we divide 609 by 72, we get 8 and a remainder of 33.
Put 8 as the next digit of the answer. 
Result so far: 58.0
If we take 576 away from 609, we end up with 33.
Take the next digit (5) from the dividend and append it to 33, then repeat: 335 / 72

Going ahead to step 5:
72 can be fit into 335 4 times, resulting in a remainder of 47.
Use 4 as the next digit of our solution. 
Result so far: 584.0
If we subtract 288 from 335, we get 47.
Append the next digit (7) from the dividend to 47 and continue with: 477 / 72

Moving on to step 6:
The number 72 fits into 477 6 times, leaving a remainder of 45.
Put 6 as the next digit of the answer. 
Result so far: 5846.0
If we subtract 432 from 477, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 7:
450 divided by 72 is 6 with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 5846.6
If we subtract 432 from 450, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
If we divide 180 by 72, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 5846.62
The remainder is 36 after subtracting 144 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
72 goes into 360 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5846.625
Subtract 360 from 360 to 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.

On to step 10:
72 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5846.625
Deduct 0 from 0 and we're left 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.

On to step 11:
If we divide 0 by 72, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5846.625
If we subtract 0 from 0, 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.

The final outcome is 5846.625, with a leftover of 0.0.
