We look at the division of 80107707 by 357 
We want to divide 80107707 by 357.

Advancing to step 1:
When dividing 8 by 357, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 357

On to step 2:
The number 357 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Take the next digit (1) from the dividend and append it to 80, then repeat: 801 / 357

On to step 3:
The number 357 fits into 801 2 times, leaving a remainder of 87.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 714 from 801, we get 87.
Append the next digit (0) from the dividend to 87 and continue with: 870 / 357

On to step 4:
The number 357 fits into 870 2 times, leaving a remainder of 156.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Deduct 714 from 870 and we're left with 156.
Append the next digit (7) from the dividend to 156 and continue with: 1567 / 357

Going ahead to step 5:
357 goes into 1567 4 times with a remainder of 139.
The number 4 becomes the next digit in our result. 
Result so far: 224.0
If we subtract 1428 from 1567, we get 139.
Fetch the next digit (7) from the dividend, attach it to 139 and continue: 1397 / 357

Going ahead to step 6:
1397 divided by 357 is 3 with a remainder of 326.
The next digit of our result is 3. 
Result so far: 2243.0
If we subtract 1071 from 1397, we get 326.
Take the next digit (0) from the dividend and append it to 326, then repeat: 3260 / 357

Step 7:
357 goes into 3260 9 times with a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 22439.0
If we subtract 3213 from 3260, we get 47.
Include the next digit (7) from the dividend after 47, then repeat: 477 / 357

On to step 8:
When dividing 477 by 357, we get 1 with a remainder of 120.
Use 1 as the next digit of our solution. 
Result so far: 224391.0
Subtracting 357 from 477 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 9:
357 goes into 1200 3 times with a remainder of 129.
Put 3 as the next digit of the answer. 
Result so far: 224391.3
Subtract 1071 from 1200 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Moving on to step 10:
357 can be fit into 1290 3 times, resulting in a remainder of 219.
Use 3 as the next digit of our solution. 
Result so far: 224391.33
If we subtract 1071 from 1290, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

The final outcome is 224391.33, with a leftover of 0.219.
