51099777 ÷ 730 
We want to figure out the number of times 51099777 can be divided by 730.

On to step 1:
The number 730 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 730

Advancing to step 2:
If we divide 51 by 730, we get 0 and a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Take the next digit (0) from the dividend and append it to 51, then repeat: 510 / 730

Let's proceed to step 3:
The number 730 fits into 510 0 times, leaving a remainder of 510.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 510, we get 510.
Grab the next digit (9) from the dividend, add it to 510, then carry on: 5109 / 730

Moving on to step 4:
If we divide 5109 by 730, we get 6 and a remainder of 729.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 4380 from 5109 and we're left with 729.
Include the next digit (9) from the dividend after 729, then repeat: 7299 / 730

Let's proceed to step 5:
7299 divided by 730 is 9 with a remainder of 729.
The next digit of our result is 9. 
Result so far: 69.0
Subtracting 6570 from 7299 leaves us with 729.
Bring next digit (7) of the dividend behind the 729 and repeat the process: 7297 / 730

On to step 6:
7297 divided by 730 is 9 with a remainder of 727.
Write down 9 as next digit of the result. 
Result so far: 699.0
The remainder is 727 after subtracting 6570 from 7297.
Fetch the next digit (7) from the dividend, attach it to 727 and continue: 7277 / 730

Going ahead to step 7:
If we divide 7277 by 730, we get 9 and a remainder of 707.
Put 9 as the next digit of the answer. 
Result so far: 6999.0
If we subtract 6570 from 7277, we get 707.
Take the next digit (7) from the dividend and append it to 707, then repeat: 7077 / 730

Let's proceed to step 8:
When dividing 7077 by 730, we get 9 with a remainder of 507.
Put 9 as the next digit of the answer. 
Result so far: 69999.0
If we take 6570 away from 7077, we end up with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

On to step 9:
5070 divided by 730 is 6 with a remainder of 690.
Put 6 as the next digit of the answer. 
Result so far: 69999.6
Subtract 4380 from 5070 to get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

On to step 10:
If we divide 6900 by 730, we get 9 and a remainder of 330.
Put 9 as the next digit of the answer. 
Result so far: 69999.69
Subtracting 6570 from 6900 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 11:
When dividing 3300 by 730, we get 4 with a remainder of 380.
Record the quotient 4 as the next digit in the result. 
Result so far: 69999.694
Subtract 2920 from 3300 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 12:
3800 divided by 730 is 5 with a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 69999.6945
Deduct 3650 from 3800 and we're left with 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 13:
1500 divided by 730 is 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 69999.69452
Subtracting 1460 from 1500 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
The number 730 fits into 400 0 times, leaving a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 69999.69452
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 15:
4000 divided by 730 is 5 with a remainder of 350.
The number 5 becomes the next digit in our result. 
Result so far: 69999.6945205
Deduct 3650 from 4000 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 16:
730 goes into 3500 4 times with a remainder of 580.
Write down 4 as next digit of the result. 
Result so far: 69999.69452054
If we subtract 2920 from 3500, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

The final result is 69999.69452054 with a remainder of 5.8e-07.
