We're dividing 72685218 by 455 
We want to figure out the number of times 72685218 can be divided by 455.

On to step 1:
When dividing 7 by 455, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 455

Advancing to step 2:
72 divided by 455 is 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Append the next digit (6) from the dividend to 72 and continue with: 726 / 455

Let's proceed to step 3:
The number 455 fits into 726 1 times, leaving a remainder of 271.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 455 from 726 and we're left with 271.
Fetch the next digit (8) from the dividend, attach it to 271 and continue: 2718 / 455

On to step 4:
The number 455 fits into 2718 5 times, leaving a remainder of 443.
The next digit of our result is 5. 
Result so far: 15.0
If we take 2275 away from 2718, we end up with 443.
Append the next digit (5) from the dividend to 443 and continue with: 4435 / 455

Let's proceed to step 5:
455 can be fit into 4435 9 times, resulting in a remainder of 340.
Use 9 as the next digit of our solution. 
Result so far: 159.0
The remainder is 340 after subtracting 4095 from 4435.
Bring next digit (2) of the dividend behind the 340 and repeat the process: 3402 / 455

Advancing to step 6:
455 can be fit into 3402 7 times, resulting in a remainder of 217.
Put 7 as the next digit of the answer. 
Result so far: 1597.0
Subtracting 3185 from 3402 leaves us with 217.
Grab the next digit (1) from the dividend, add it to 217, then carry on: 2171 / 455

Let's proceed to step 7:
2171 divided by 455 is 4 with a remainder of 351.
Put 4 as the next digit of the answer. 
Result so far: 15974.0
Subtracting 1820 from 2171 leaves us with 351.
Grab the next digit (8) from the dividend, add it to 351, then carry on: 3518 / 455

Advancing to step 8:
The number 455 fits into 3518 7 times, leaving a remainder of 333.
Put 7 as the next digit of the answer. 
Result so far: 159747.0
Deduct 3185 from 3518 and we're left with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Step 9:
The number 455 fits into 3330 7 times, leaving a remainder of 145.
The number 7 becomes the next digit in our result. 
Result so far: 159747.7
The remainder is 145 after subtracting 3185 from 3330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 10:
If we divide 1450 by 455, we get 3 and a remainder of 85.
The number 3 becomes the next digit in our result. 
Result so far: 159747.73
Subtract 1365 from 1450 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 11:
850 divided by 455 is 1 with a remainder of 395.
Record the quotient 1 as the next digit in the result. 
Result so far: 159747.731
If we take 455 away from 850, we end up with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

On to step 12:
The number 455 fits into 3950 8 times, leaving a remainder of 310.
Record the quotient 8 as the next digit in the result. 
Result so far: 159747.7318
Deduct 3640 from 3950 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 13:
When dividing 3100 by 455, we get 6 with a remainder of 370.
Record the quotient 6 as the next digit in the result. 
Result so far: 159747.73186
Subtracting 2730 from 3100 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 14:
When dividing 3700 by 455, we get 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 159747.731868
The remainder is 60 after subtracting 3640 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 15:
455 can be fit into 600 1 times, resulting in a remainder of 145.
Write down 1 as next digit of the result. 
Result so far: 159747.7318681
Subtract 455 from 600 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 16:
If we divide 1450 by 455, we get 3 and a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 159747.73186813
Deduct 1365 from 1450 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final result is 159747.73186813 with a remainder of 8.5e-08.
