72439211 divided by 423 
We want to divide 72439211 by 423.

Going ahead to step 1:
When dividing 7 by 423, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
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

Moving on to step 2:
If we divide 72 by 423, we get 0 and a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Bring next digit (4) of the dividend behind the 72 and repeat the process: 724 / 423

Let's proceed to step 3:
When dividing 724 by 423, we get 1 with a remainder of 301.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 423 from 724, we get 301.
Take the next digit (3) from the dividend and append it to 301, then repeat: 3013 / 423

Let's proceed to step 4:
423 goes into 3013 7 times with a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 52 after subtracting 2961 from 3013.
Fetch the next digit (9) from the dividend, attach it to 52 and continue: 529 / 423

Going ahead to step 5:
529 divided by 423 is 1 with a remainder of 106.
Use 1 as the next digit of our solution. 
Result so far: 171.0
If we subtract 423 from 529, we get 106.
Include the next digit (2) from the dividend after 106, then repeat: 1062 / 423

Step 6:
1062 divided by 423 is 2 with a remainder of 216.
The number 2 becomes the next digit in our result. 
Result so far: 1712.0
Subtracting 846 from 1062 leaves us with 216.
Grab the next digit (1) from the dividend, add it to 216, then carry on: 2161 / 423

Advancing to step 7:
2161 divided by 423 is 5 with a remainder of 46.
Put 5 as the next digit of the answer. 
Result so far: 17125.0
The remainder is 46 after subtracting 2115 from 2161.
Fetch the next digit (1) from the dividend, attach it to 46 and continue: 461 / 423

Step 8:
423 can be fit into 461 1 times, resulting in a remainder of 38.
The next digit of our result is 1. 
Result so far: 171251.0
If we subtract 423 from 461, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
The number 423 fits into 380 0 times, leaving a remainder of 380.
Put 0 as the next digit of the answer. 
Result so far: 171251.0
If we subtract 0 from 380, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 10:
When dividing 3800 by 423, we get 8 with a remainder of 416.
Use 8 as the next digit of our solution. 
Result so far: 171251.08
Deduct 3384 from 3800 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 11:
When dividing 4160 by 423, we get 9 with a remainder of 353.
Write down 9 as next digit of the result. 
Result so far: 171251.089
The remainder is 353 after subtracting 3807 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Let's proceed to step 12:
If we divide 3530 by 423, we get 8 and a remainder of 146.
Put 8 as the next digit of the answer. 
Result so far: 171251.0898
The remainder is 146 after subtracting 3384 from 3530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 13:
423 can be fit into 1460 3 times, resulting in a remainder of 191.
Write down 3 as next digit of the result. 
Result so far: 171251.08983
Subtracting 1269 from 1460 leaves us with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Moving on to step 14:
When dividing 1910 by 423, we get 4 with a remainder of 218.
The number 4 becomes the next digit in our result. 
Result so far: 171251.089834
If we subtract 1692 from 1910, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 15:
When dividing 2180 by 423, we get 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 171251.0898345
If we take 2115 away from 2180, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 16:
If we divide 650 by 423, we get 1 and a remainder of 227.
Write down 1 as next digit of the result. 
Result so far: 171251.08983451
Subtracting 423 from 650 leaves us with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

The final result is 171251.08983451 with a remainder of 2.27e-07.
