77307051 ÷ 100 
We want to divide 77307051 by 100.

Step 1:
If we divide 7 by 100, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 100

Moving on to step 2:
If we divide 77 by 100, we get 0 and a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 100

Going ahead to step 3:
If we divide 773 by 100, we get 7 and a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 73 after subtracting 700 from 773.
Append the next digit (0) from the dividend to 73 and continue with: 730 / 100

Moving on to step 4:
When dividing 730 by 100, we get 7 with a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 77.0
If we take 700 away from 730, we end up with 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 100

Advancing to step 5:
307 divided by 100 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 773.0
If we take 300 away from 307, we end up with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 100

On to step 6:
When dividing 70 by 100, we get 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 7730.0
Deduct 0 from 70 and we're left with 70.
Append the next digit (5) from the dividend to 70 and continue with: 705 / 100

Moving on to step 7:
100 can be fit into 705 7 times, resulting in a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 77307.0
If we subtract 700 from 705, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 100

On to step 8:
If we divide 51 by 100, we get 0 and a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 773070.0
Deduct 0 from 51 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 9:
100 can be fit into 510 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 773070.5
Subtracting 500 from 510 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
100 divided by 100 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 773070.51
Subtract 100 from 100 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
When dividing 0 by 100, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 773070.51
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
100 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 773070.51
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 773070.51 with a remainder of 0.0.
