We're dividing 72945489 by 812 
We want to figure out the number of times 72945489 can be divided by 812.

Step 1:
812 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 812

Moving on to step 2:
If we divide 72 by 812, we get 0 and a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Take the next digit (9) from the dividend and append it to 72, then repeat: 729 / 812

Moving on to step 3:
When dividing 729 by 812, we get 0 with a remainder of 729.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 729 and we're left with 729.
Bring next digit (4) of the dividend behind the 729 and repeat the process: 7294 / 812

On to step 4:
812 goes into 7294 8 times with a remainder of 798.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 798 after subtracting 6496 from 7294.
Fetch the next digit (5) from the dividend, attach it to 798 and continue: 7985 / 812

Going ahead to step 5:
If we divide 7985 by 812, we get 9 and a remainder of 677.
Put 9 as the next digit of the answer. 
Result so far: 89.0
If we subtract 7308 from 7985, we get 677.
Grab the next digit (4) from the dividend, add it to 677, then carry on: 6774 / 812

Advancing to step 6:
6774 divided by 812 is 8 with a remainder of 278.
The number 8 becomes the next digit in our result. 
Result so far: 898.0
Subtracting 6496 from 6774 leaves us with 278.
Bring next digit (8) of the dividend behind the 278 and repeat the process: 2788 / 812

On to step 7:
812 can be fit into 2788 3 times, resulting in a remainder of 352.
Put 3 as the next digit of the answer. 
Result so far: 8983.0
If we subtract 2436 from 2788, we get 352.
Take the next digit (9) from the dividend and append it to 352, then repeat: 3529 / 812

Moving on to step 8:
3529 divided by 812 is 4 with a remainder of 281.
Write down 4 as next digit of the result. 
Result so far: 89834.0
If we take 3248 away from 3529, we end up with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Moving on to step 9:
If we divide 2810 by 812, we get 3 and a remainder of 374.
Use 3 as the next digit of our solution. 
Result so far: 89834.3
If we subtract 2436 from 2810, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

On to step 10:
812 can be fit into 3740 4 times, resulting in a remainder of 492.
Use 4 as the next digit of our solution. 
Result so far: 89834.34
If we take 3248 away from 3740, we end up with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Let's proceed to step 11:
The number 812 fits into 4920 6 times, leaving a remainder of 48.
The next digit of our result is 6. 
Result so far: 89834.346
If we take 4872 away from 4920, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
When dividing 480 by 812, we get 0 with a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 89834.346
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 13:
When dividing 4800 by 812, we get 5 with a remainder of 740.
The next digit of our result is 5. 
Result so far: 89834.34605
If we take 4060 away from 4800, we end up with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

On to step 14:
812 goes into 7400 9 times with a remainder of 92.
The number 9 becomes the next digit in our result. 
Result so far: 89834.346059
Deduct 7308 from 7400 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 15:
When dividing 920 by 812, we get 1 with a remainder of 108.
Write down 1 as next digit of the result. 
Result so far: 89834.3460591
If we take 812 away from 920, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 16:
812 can be fit into 1080 1 times, resulting in a remainder of 268.
Put 1 as the next digit of the answer. 
Result so far: 89834.34605911
Subtracting 812 from 1080 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

In conclusion, the division gives 89834.34605911 with a balance of 2.68e-07.
