Let's divide 80115918 by 105
We're looking to find how many times 105 goes into 80115918.

Moving on to step 1:
The number 105 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 105

Step 2:
The number 105 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Include the next digit (1) from the dividend after 80, then repeat: 801 / 105

On to step 3:
105 goes into 801 7 times with a remainder of 66.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 735 from 801, we get 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 105

Advancing to step 4:
If we divide 661 by 105, we get 6 and a remainder of 31.
Put 6 as the next digit of the answer. 
Result so far: 76.0
If we take 630 away from 661, we end up with 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 105

Moving on to step 5:
105 can be fit into 315 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 763.0
Deduct 315 from 315 and we're left with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 105

Let's proceed to step 6:
105 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 7630.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 105

Going ahead to step 7:
The number 105 fits into 91 0 times, leaving a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 76300.0
The remainder is 91 after subtracting 0 from 91.
Append the next digit (8) from the dividend to 91 and continue with: 918 / 105

Advancing to step 8:
The number 105 fits into 918 8 times, leaving a remainder of 78.
Record the quotient 8 as the next digit in the result. 
Result so far: 763008.0
If we take 840 away from 918, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 9:
The number 105 fits into 780 7 times, leaving a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 763008.7
The remainder is 45 after subtracting 735 from 780.
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 10:
If we divide 450 by 105, we get 4 and a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 763008.74
If we take 420 away from 450, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
When dividing 300 by 105, we get 2 with a remainder of 90.
Put 2 as the next digit of the answer. 
Result so far: 763008.742
Subtract 210 from 300 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 12:
The number 105 fits into 900 8 times, leaving a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 763008.7428
Subtract 840 from 900 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 13:
The number 105 fits into 600 5 times, leaving a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 763008.74285
Subtract 525 from 600 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 14:
750 divided by 105 is 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 763008.742857
If we take 735 away from 750, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 15:
150 divided by 105 is 1 with a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 763008.7428571
If we take 105 away from 150, we end up with 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 16:
The number 105 fits into 450 4 times, leaving a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 763008.74285714
If we take 420 away from 450, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 763008.74285714 and a remainder of 3e-08.
