We look at the division of 72288172 by 181 
We're looking to find how many times 181 goes into 72288172.

Moving on to step 1:
181 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 181

Going ahead to step 2:
When dividing 72 by 181, we get 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Include the next digit (2) from the dividend after 72, then repeat: 722 / 181

Let's proceed to step 3:
181 can be fit into 722 3 times, resulting in a remainder of 179.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 543 from 722 to get 179.
Grab the next digit (8) from the dividend, add it to 179, then carry on: 1798 / 181

On to step 4:
1798 divided by 181 is 9 with a remainder of 169.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we take 1629 away from 1798, we end up with 169.
Grab the next digit (8) from the dividend, add it to 169, then carry on: 1698 / 181

On to step 5:
The number 181 fits into 1698 9 times, leaving a remainder of 69.
The next digit of our result is 9. 
Result so far: 399.0
If we take 1629 away from 1698, we end up with 69.
Fetch the next digit (1) from the dividend, attach it to 69 and continue: 691 / 181

On to step 6:
691 divided by 181 is 3 with a remainder of 148.
Record the quotient 3 as the next digit in the result. 
Result so far: 3993.0
Subtracting 543 from 691 leaves us with 148.
Bring next digit (7) of the dividend behind the 148 and repeat the process: 1487 / 181

Advancing to step 7:
If we divide 1487 by 181, we get 8 and a remainder of 39.
Write down 8 as next digit of the result. 
Result so far: 39938.0
If we take 1448 away from 1487, we end up with 39.
Grab the next digit (2) from the dividend, add it to 39, then carry on: 392 / 181

On to step 8:
The number 181 fits into 392 2 times, leaving a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 399382.0
If we take 362 away from 392, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
300 divided by 181 is 1 with a remainder of 119.
The number 1 becomes the next digit in our result. 
Result so far: 399382.1
Subtract 181 from 300 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 10:
181 can be fit into 1190 6 times, resulting in a remainder of 104.
Use 6 as the next digit of our solution. 
Result so far: 399382.16
If we take 1086 away from 1190, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 11:
181 goes into 1040 5 times with a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 399382.165
If we subtract 905 from 1040, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 12:
If we divide 1350 by 181, we get 7 and a remainder of 83.
The next digit of our result is 7. 
Result so far: 399382.1657
Subtracting 1267 from 1350 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 13:
If we divide 830 by 181, we get 4 and a remainder of 106.
The number 4 becomes the next digit in our result. 
Result so far: 399382.16574
The remainder is 106 after subtracting 724 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 14:
181 can be fit into 1060 5 times, resulting in a remainder of 155.
The next digit of our result is 5. 
Result so far: 399382.165745
If we subtract 905 from 1060, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 15:
If we divide 1550 by 181, we get 8 and a remainder of 102.
Put 8 as the next digit of the answer. 
Result so far: 399382.1657458
Subtracting 1448 from 1550 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 16:
1020 divided by 181 is 5 with a remainder of 115.
Write down 5 as next digit of the result. 
Result so far: 399382.16574585
Deduct 905 from 1020 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

In conclusion, the division gives 399382.16574585 with a balance of 1.15e-07.
