We're dividing 72704237 by 455 
We want to divide 72704237 by 455.

Moving on to step 1:
If we divide 7 by 455, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
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 / 455

Moving on 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
Subtract 0 from 72 to get 72.
Append the next digit (7) from the dividend to 72 and continue with: 727 / 455

Let's proceed to step 3:
The number 455 fits into 727 1 times, leaving a remainder of 272.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 455 from 727 to get 272.
Grab the next digit (0) from the dividend, add it to 272, then carry on: 2720 / 455

Going ahead to step 4:
If we divide 2720 by 455, we get 5 and a remainder of 445.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 2275 from 2720 leaves us with 445.
Fetch the next digit (4) from the dividend, attach it to 445 and continue: 4454 / 455

On to step 5:
4454 divided by 455 is 9 with a remainder of 359.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
Subtract 4095 from 4454 to get 359.
Grab the next digit (2) from the dividend, add it to 359, then carry on: 3592 / 455

Going ahead to step 6:
455 goes into 3592 7 times with a remainder of 407.
Record the quotient 7 as the next digit in the result. 
Result so far: 1597.0
The remainder is 407 after subtracting 3185 from 3592.
Append the next digit (3) from the dividend to 407 and continue with: 4073 / 455

Moving on to step 7:
455 goes into 4073 8 times with a remainder of 433.
Use 8 as the next digit of our solution. 
Result so far: 15978.0
The remainder is 433 after subtracting 3640 from 4073.
Append the next digit (7) from the dividend to 433 and continue with: 4337 / 455

Advancing to step 8:
4337 divided by 455 is 9 with a remainder of 242.
The next digit of our result is 9. 
Result so far: 159789.0
If we take 4095 away from 4337, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Step 9:
The number 455 fits into 2420 5 times, leaving a remainder of 145.
Record the quotient 5 as the next digit in the result. 
Result so far: 159789.5
If we subtract 2275 from 2420, we 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.

Advancing to step 10:
1450 divided by 455 is 3 with a remainder of 85.
Put 3 as the next digit of the answer. 
Result so far: 159789.53
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:
When dividing 850 by 455, we get 1 with a remainder of 395.
The number 1 becomes the next digit in our result. 
Result so far: 159789.531
Subtracting 455 from 850 leaves us 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.

Advancing to step 12:
If we divide 3950 by 455, we get 8 and a remainder of 310.
The number 8 becomes the next digit in our result. 
Result so far: 159789.5318
Subtracting 3640 from 3950 leaves us 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.

Let's proceed to step 13:
The number 455 fits into 3100 6 times, leaving a remainder of 370.
The number 6 becomes the next digit in our result. 
Result so far: 159789.53186
Subtract 2730 from 3100 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 14:
3700 divided by 455 is 8 with a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 159789.531868
If we subtract 3640 from 3700, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 15:
455 can be fit into 600 1 times, resulting in a remainder of 145.
Use 1 as the next digit of our solution. 
Result so far: 159789.5318681
The remainder is 145 after subtracting 455 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 16:
455 can be fit into 1450 3 times, resulting in a remainder of 85.
The next digit of our result is 3. 
Result so far: 159789.53186813
The remainder is 85 after subtracting 1365 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

After the division, we end up with 159789.53186813 and a remainder of 8.5e-08.
