We're dividing 72144069 by 434 
We want to divide 72144069 by 434.

Let's proceed to step 1:
If we divide 7 by 434, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 434

Advancing to step 2:
72 divided by 434 is 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 434

Advancing to step 3:
434 can be fit into 721 1 times, resulting in a remainder of 287.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 434 from 721 leaves us with 287.
Bring next digit (4) of the dividend behind the 287 and repeat the process: 2874 / 434

Let's proceed to step 4:
When dividing 2874 by 434, we get 6 with a remainder of 270.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 2604 from 2874 to get 270.
Include the next digit (4) from the dividend after 270, then repeat: 2704 / 434

Moving on to step 5:
If we divide 2704 by 434, we get 6 and a remainder of 100.
Record the quotient 6 as the next digit in the result. 
Result so far: 166.0
Subtract 2604 from 2704 to get 100.
Append the next digit (0) from the dividend to 100 and continue with: 1000 / 434

Step 6:
1000 divided by 434 is 2 with a remainder of 132.
Record the quotient 2 as the next digit in the result. 
Result so far: 1662.0
If we subtract 868 from 1000, we get 132.
Append the next digit (6) from the dividend to 132 and continue with: 1326 / 434

Advancing to step 7:
434 can be fit into 1326 3 times, resulting in a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 16623.0
Deduct 1302 from 1326 and we're left with 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 434

Moving on to step 8:
When dividing 249 by 434, we get 0 with a remainder of 249.
Record the quotient 0 as the next digit in the result. 
Result so far: 166230.0
The remainder is 249 after subtracting 0 from 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Moving on to step 9:
When dividing 2490 by 434, we get 5 with a remainder of 320.
Write down 5 as next digit of the result. 
Result so far: 166230.5
The remainder is 320 after subtracting 2170 from 2490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 10:
If we divide 3200 by 434, we get 7 and a remainder of 162.
The number 7 becomes the next digit in our result. 
Result so far: 166230.57
The remainder is 162 after subtracting 3038 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 11:
1620 divided by 434 is 3 with a remainder of 318.
Put 3 as the next digit of the answer. 
Result so far: 166230.573
Deduct 1302 from 1620 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

On to step 12:
3180 divided by 434 is 7 with a remainder of 142.
Write down 7 as next digit of the result. 
Result so far: 166230.5737
Deduct 3038 from 3180 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 13:
The number 434 fits into 1420 3 times, leaving a remainder of 118.
Record the quotient 3 as the next digit in the result. 
Result so far: 166230.57373
The remainder is 118 after subtracting 1302 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 14:
When dividing 1180 by 434, we get 2 with a remainder of 312.
The number 2 becomes the next digit in our result. 
Result so far: 166230.573732
Subtract 868 from 1180 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 15:
The number 434 fits into 3120 7 times, leaving a remainder of 82.
Write down 7 as next digit of the result. 
Result so far: 166230.5737327
The remainder is 82 after subtracting 3038 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 16:
434 goes into 820 1 times with a remainder of 386.
The number 1 becomes the next digit in our result. 
Result so far: 166230.57373271
If we take 434 away from 820, we end up with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Our division results in 166230.57373271 with a remaining 3.86e-07.
