We're dividing 72351348 by 423 
Let's see how many times 423 fits into 72351348.

Advancing to step 1:
If we divide 7 by 423, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 423

Advancing to step 2:
When dividing 72 by 423, we get 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Bring next digit (3) of the dividend behind the 72 and repeat the process: 723 / 423

Let's proceed to step 3:
If we divide 723 by 423, we get 1 and a remainder of 300.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 423 from 723 and we're left with 300.
Include the next digit (5) from the dividend after 300, then repeat: 3005 / 423

Step 4:
423 can be fit into 3005 7 times, resulting in a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtract 2961 from 3005 to get 44.
Append the next digit (1) from the dividend to 44 and continue with: 441 / 423

On to step 5:
If we divide 441 by 423, we get 1 and a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 171.0
The remainder is 18 after subtracting 423 from 441.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 423

Advancing to step 6:
If we divide 183 by 423, we get 0 and a remainder of 183.
Put 0 as the next digit of the answer. 
Result so far: 1710.0
Deduct 0 from 183 and we're left with 183.
Take the next digit (4) from the dividend and append it to 183, then repeat: 1834 / 423

Moving on to step 7:
If we divide 1834 by 423, we get 4 and a remainder of 142.
Record the quotient 4 as the next digit in the result. 
Result so far: 17104.0
Subtract 1692 from 1834 to get 142.
Fetch the next digit (8) from the dividend, attach it to 142 and continue: 1428 / 423

On to step 8:
423 can be fit into 1428 3 times, resulting in a remainder of 159.
Put 3 as the next digit of the answer. 
Result so far: 171043.0
The remainder is 159 after subtracting 1269 from 1428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Going ahead to step 9:
1590 divided by 423 is 3 with a remainder of 321.
Put 3 as the next digit of the answer. 
Result so far: 171043.3
Subtracting 1269 from 1590 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Step 10:
The number 423 fits into 3210 7 times, leaving a remainder of 249.
Write down 7 as next digit of the result. 
Result so far: 171043.37
Deduct 2961 from 3210 and we're left with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Advancing to step 11:
423 goes into 2490 5 times with a remainder of 375.
Write down 5 as next digit of the result. 
Result so far: 171043.375
If we subtract 2115 from 2490, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Going ahead to step 12:
The number 423 fits into 3750 8 times, leaving a remainder of 366.
Record the quotient 8 as the next digit in the result. 
Result so far: 171043.3758
The remainder is 366 after subtracting 3384 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Moving on to step 13:
423 goes into 3660 8 times with a remainder of 276.
The next digit of our result is 8. 
Result so far: 171043.37588
Subtract 3384 from 3660 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

The final outcome is 171043.37588, with a leftover of 0.000276.
