We look at the division of 72129069 by 440 
Let's see how many times 440 fits into 72129069.

Moving on to step 1:
When dividing 7 by 440, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 440

On to step 2:
440 can be fit into 72 0 times, resulting in 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.
Append the next digit (1) from the dividend to 72 and continue with: 721 / 440

Moving on to step 3:
When dividing 721 by 440, we get 1 with a remainder of 281.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 440 away from 721, we end up with 281.
Append the next digit (2) from the dividend to 281 and continue with: 2812 / 440

On to step 4:
When dividing 2812 by 440, we get 6 with a remainder of 172.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 2640 from 2812 and we're left with 172.
Include the next digit (9) from the dividend after 172, then repeat: 1729 / 440

Moving on to step 5:
440 can be fit into 1729 3 times, resulting in a remainder of 409.
Write down 3 as next digit of the result. 
Result so far: 163.0
If we subtract 1320 from 1729, we get 409.
Take the next digit (0) from the dividend and append it to 409, then repeat: 4090 / 440

Moving on to step 6:
440 can be fit into 4090 9 times, resulting in a remainder of 130.
Put 9 as the next digit of the answer. 
Result so far: 1639.0
Deduct 3960 from 4090 and we're left with 130.
Fetch the next digit (6) from the dividend, attach it to 130 and continue: 1306 / 440

On to step 7:
When dividing 1306 by 440, we get 2 with a remainder of 426.
Record the quotient 2 as the next digit in the result. 
Result so far: 16392.0
If we take 880 away from 1306, we end up with 426.
Include the next digit (9) from the dividend after 426, then repeat: 4269 / 440

Step 8:
The number 440 fits into 4269 9 times, leaving a remainder of 309.
Put 9 as the next digit of the answer. 
Result so far: 163929.0
Subtract 3960 from 4269 to get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Moving on to step 9:
The number 440 fits into 3090 7 times, leaving a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 163929.7
Deduct 3080 from 3090 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
440 goes into 100 0 times with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 163929.7
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
The number 440 fits into 1000 2 times, leaving a remainder of 120.
Record the quotient 2 as the next digit in the result. 
Result so far: 163929.702
Deduct 880 from 1000 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 12:
1200 divided by 440 is 2 with a remainder of 320.
Put 2 as the next digit of the answer. 
Result so far: 163929.7022
Subtracting 880 from 1200 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final result is 163929.7022 with a remainder of 0.0032.
