Let's divide 72779921 by 455
Our goal is to divide 72779921 by 455.

Let's proceed to step 1:
455 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 455

Advancing to step 2:
The number 455 fits into 72 0 times, leaving a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Take the next digit (7) from the dividend and append it to 72, then repeat: 727 / 455

On to step 3:
The number 455 fits into 727 1 times, leaving a remainder of 272.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 455 from 727 to get 272.
Take the next digit (7) from the dividend and append it to 272, then repeat: 2727 / 455

Moving on to step 4:
455 can be fit into 2727 5 times, resulting in a remainder of 452.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 452 after subtracting 2275 from 2727.
Bring next digit (9) of the dividend behind the 452 and repeat the process: 4529 / 455

Advancing to step 5:
The number 455 fits into 4529 9 times, leaving a remainder of 434.
Record the quotient 9 as the next digit in the result. 
Result so far: 159.0
The remainder is 434 after subtracting 4095 from 4529.
Bring next digit (9) of the dividend behind the 434 and repeat the process: 4349 / 455

Moving on to step 6:
The number 455 fits into 4349 9 times, leaving a remainder of 254.
The next digit of our result is 9. 
Result so far: 1599.0
Subtracting 4095 from 4349 leaves us with 254.
Bring next digit (2) of the dividend behind the 254 and repeat the process: 2542 / 455

Going ahead to step 7:
455 goes into 2542 5 times with a remainder of 267.
Use 5 as the next digit of our solution. 
Result so far: 15995.0
Subtracting 2275 from 2542 leaves us with 267.
Bring next digit (1) of the dividend behind the 267 and repeat the process: 2671 / 455

Let's proceed to step 8:
455 can be fit into 2671 5 times, resulting in a remainder of 396.
Use 5 as the next digit of our solution. 
Result so far: 159955.0
The remainder is 396 after subtracting 2275 from 2671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 9:
When dividing 3960 by 455, we get 8 with a remainder of 320.
Record the quotient 8 as the next digit in the result. 
Result so far: 159955.8
Deduct 3640 from 3960 and we're left 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.

Advancing to step 10:
455 goes into 3200 7 times with a remainder of 15.
The next digit of our result is 7. 
Result so far: 159955.87
Subtracting 3185 from 3200 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
455 goes into 150 0 times with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 159955.87
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 12:
1500 divided by 455 is 3 with a remainder of 135.
Put 3 as the next digit of the answer. 
Result so far: 159955.8703
Subtracting 1365 from 1500 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 13:
When dividing 1350 by 455, we get 2 with a remainder of 440.
Use 2 as the next digit of our solution. 
Result so far: 159955.87032
Subtracting 910 from 1350 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 14:
4400 divided by 455 is 9 with a remainder of 305.
Record the quotient 9 as the next digit in the result. 
Result so far: 159955.870329
If we subtract 4095 from 4400, we get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Step 15:
When dividing 3050 by 455, we get 6 with a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 159955.8703296
Subtracting 2730 from 3050 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.

Advancing to step 16:
455 can be fit into 3200 7 times, resulting in a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 159955.87032967
Deduct 3185 from 3200 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 159955.87032967, with a leftover of 1.5e-08.
