We're dividing 72639075 by 451 
We're looking to find how many times 451 goes into 72639075.

On to step 1:
451 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 451

Moving on to step 2:
451 goes into 72 0 times with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Append the next digit (6) from the dividend to 72 and continue with: 726 / 451

Let's proceed to step 3:
726 divided by 451 is 1 with a remainder of 275.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 275 after subtracting 451 from 726.
Append the next digit (3) from the dividend to 275 and continue with: 2753 / 451

Step 4:
When dividing 2753 by 451, we get 6 with a remainder of 47.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 2706 from 2753 to get 47.
Append the next digit (9) from the dividend to 47 and continue with: 479 / 451

Advancing to step 5:
When dividing 479 by 451, we get 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 161.0
If we subtract 451 from 479, we get 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 451

Advancing to step 6:
280 divided by 451 is 0 with a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 1610.0
The remainder is 280 after subtracting 0 from 280.
Include the next digit (7) from the dividend after 280, then repeat: 2807 / 451

Going ahead to step 7:
451 goes into 2807 6 times with a remainder of 101.
The number 6 becomes the next digit in our result. 
Result so far: 16106.0
If we take 2706 away from 2807, we end up with 101.
Bring next digit (5) of the dividend behind the 101 and repeat the process: 1015 / 451

On to step 8:
1015 divided by 451 is 2 with a remainder of 113.
Use 2 as the next digit of our solution. 
Result so far: 161062.0
The remainder is 113 after subtracting 902 from 1015.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Advancing to step 9:
If we divide 1130 by 451, we get 2 and a remainder of 228.
The number 2 becomes the next digit in our result. 
Result so far: 161062.2
Subtracting 902 from 1130 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 10:
When dividing 2280 by 451, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 161062.25
Subtracting 2255 from 2280 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 11:
If we divide 250 by 451, we get 0 and a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 161062.25
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 12:
451 can be fit into 2500 5 times, resulting in a remainder of 245.
The number 5 becomes the next digit in our result. 
Result so far: 161062.2505
The remainder is 245 after subtracting 2255 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Advancing to step 13:
If we divide 2450 by 451, we get 5 and a remainder of 195.
Write down 5 as next digit of the result. 
Result so far: 161062.25055
Subtract 2255 from 2450 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

After the division, we end up with 161062.25055 and a remainder of 0.000195.
