We divide 72774506 by 645
We want to figure out the number of times 72774506 can be divided by 645.

Moving on to step 1:
The number 645 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
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 / 645

Step 2:
72 divided by 645 is 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Include the next digit (7) from the dividend after 72, then repeat: 727 / 645

Step 3:
The number 645 fits into 727 1 times, leaving a remainder of 82.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 82 after subtracting 645 from 727.
Bring next digit (7) of the dividend behind the 82 and repeat the process: 827 / 645

Moving on to step 4:
If we divide 827 by 645, we get 1 and a remainder of 182.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 182 after subtracting 645 from 827.
Bring next digit (4) of the dividend behind the 182 and repeat the process: 1824 / 645

On to step 5:
When dividing 1824 by 645, we get 2 with a remainder of 534.
Put 2 as the next digit of the answer. 
Result so far: 112.0
Subtract 1290 from 1824 to get 534.
Fetch the next digit (5) from the dividend, attach it to 534 and continue: 5345 / 645

Step 6:
When dividing 5345 by 645, we get 8 with a remainder of 185.
The next digit of our result is 8. 
Result so far: 1128.0
If we take 5160 away from 5345, we end up with 185.
Include the next digit (0) from the dividend after 185, then repeat: 1850 / 645

On to step 7:
645 goes into 1850 2 times with a remainder of 560.
Write down 2 as next digit of the result. 
Result so far: 11282.0
The remainder is 560 after subtracting 1290 from 1850.
Fetch the next digit (6) from the dividend, attach it to 560 and continue: 5606 / 645

Moving on to step 8:
645 goes into 5606 8 times with a remainder of 446.
Use 8 as the next digit of our solution. 
Result so far: 112828.0
If we take 5160 away from 5606, we end up with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Moving on to step 9:
When dividing 4460 by 645, we get 6 with a remainder of 590.
The next digit of our result is 6. 
Result so far: 112828.6
The remainder is 590 after subtracting 3870 from 4460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Advancing to step 10:
If we divide 5900 by 645, we get 9 and a remainder of 95.
The number 9 becomes the next digit in our result. 
Result so far: 112828.69
Deduct 5805 from 5900 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 11:
When dividing 950 by 645, we get 1 with a remainder of 305.
Put 1 as the next digit of the answer. 
Result so far: 112828.691
Subtracting 645 from 950 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Let's proceed to step 12:
If we divide 3050 by 645, we get 4 and a remainder of 470.
Use 4 as the next digit of our solution. 
Result so far: 112828.6914
Subtracting 2580 from 3050 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Moving on to step 13:
645 can be fit into 4700 7 times, resulting in a remainder of 185.
Put 7 as the next digit of the answer. 
Result so far: 112828.69147
If we subtract 4515 from 4700, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 14:
1850 divided by 645 is 2 with a remainder of 560.
Use 2 as the next digit of our solution. 
Result so far: 112828.691472
If we subtract 1290 from 1850, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 15:
5600 divided by 645 is 8 with a remainder of 440.
Use 8 as the next digit of our solution. 
Result so far: 112828.6914728
Deduct 5160 from 5600 and we're left 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.

Advancing to step 16:
645 goes into 4400 6 times with a remainder of 530.
Put 6 as the next digit of the answer. 
Result so far: 112828.69147286
Subtracting 3870 from 4400 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

In conclusion, the division gives 112828.69147286 with a balance of 5.3e-07.
