81777300 divided by 51 
We want to figure out the number of times 81777300 can be divided by 51.

Going ahead to step 1:
8 divided by 51 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 51

Let's proceed to step 2:
When dividing 81 by 51, we get 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 51 away from 81, we end up with 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 51

Moving on to step 3:
When dividing 307 by 51, we get 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 306 from 307 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 51

On to step 4:
When dividing 17 by 51, we get 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 160.0
Subtracting 0 from 17 leaves us with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 51

Going ahead to step 5:
If we divide 177 by 51, we get 3 and a remainder of 24.
The next digit of our result is 3. 
Result so far: 1603.0
If we take 153 away from 177, we end up with 24.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 51

Advancing to step 6:
51 goes into 243 4 times with a remainder of 39.
Write down 4 as next digit of the result. 
Result so far: 16034.0
Subtract 204 from 243 to get 39.
Fetch the next digit (0) from the dividend, attach it to 39 and continue: 390 / 51

Going ahead to step 7:
51 can be fit into 390 7 times, resulting in a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 160347.0
If we subtract 357 from 390, we get 33.
Fetch the next digit (0) from the dividend, attach it to 33 and continue: 330 / 51

Moving on to step 8:
The number 51 fits into 330 6 times, leaving a remainder of 24.
The next digit of our result is 6. 
Result so far: 1603476.0
Subtract 306 from 330 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
51 can be fit into 240 4 times, resulting in a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 1603476.4
Subtract 204 from 240 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
The number 51 fits into 360 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 1603476.47
If we take 357 away from 360, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 11:
When dividing 30 by 51, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 1603476.47
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
If we divide 300 by 51, we get 5 and a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 1603476.4705
Subtract 255 from 300 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 13:
51 can be fit into 450 8 times, resulting in a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 1603476.47058
The remainder is 42 after subtracting 408 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 14:
If we divide 420 by 51, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 1603476.470588
Subtract 408 from 420 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 1603476.470588 and a remainder of 1.2e-06.
