Let's divide 80109689 by 105
We want to divide 80109689 by 105.

Advancing to step 1:
105 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 105

Moving on to step 2:
105 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Bring next digit (1) of the dividend behind the 80 and repeat the process: 801 / 105

Going ahead to step 3:
105 goes into 801 7 times with a remainder of 66.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 735 from 801 to get 66.
Include the next digit (0) from the dividend after 66, then repeat: 660 / 105

Moving on to step 4:
660 divided by 105 is 6 with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Subtract 630 from 660 to get 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 105

Advancing to step 5:
When dividing 309 by 105, we get 2 with a remainder of 99.
The next digit of our result is 2. 
Result so far: 762.0
If we take 210 away from 309, we end up with 99.
Take the next digit (6) from the dividend and append it to 99, then repeat: 996 / 105

Moving on to step 6:
105 goes into 996 9 times with a remainder of 51.
The next digit of our result is 9. 
Result so far: 7629.0
If we take 945 away from 996, we end up with 51.
Bring next digit (8) of the dividend behind the 51 and repeat the process: 518 / 105

Let's proceed to step 7:
518 divided by 105 is 4 with a remainder of 98.
The number 4 becomes the next digit in our result. 
Result so far: 76294.0
If we subtract 420 from 518, we get 98.
Grab the next digit (9) from the dividend, add it to 98, then carry on: 989 / 105

Going ahead to step 8:
105 can be fit into 989 9 times, resulting in a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 762949.0
The remainder is 44 after subtracting 945 from 989.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
105 can be fit into 440 4 times, resulting in a remainder of 20.
The next digit of our result is 4. 
Result so far: 762949.4
The remainder is 20 after subtracting 420 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
105 can be fit into 200 1 times, resulting in a remainder of 95.
Record the quotient 1 as the next digit in the result. 
Result so far: 762949.41
Subtract 105 from 200 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 11:
If we divide 950 by 105, we get 9 and a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 762949.419
The remainder is 5 after subtracting 945 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
When dividing 50 by 105, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 762949.419
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
105 can be fit into 500 4 times, resulting in a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 762949.41904
The remainder is 80 after subtracting 420 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 14:
105 goes into 800 7 times with a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 762949.419047
Subtracting 735 from 800 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 15:
When dividing 650 by 105, we get 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 762949.4190476
The remainder is 20 after subtracting 630 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 16:
105 can be fit into 200 1 times, resulting in a remainder of 95.
The number 1 becomes the next digit in our result. 
Result so far: 762949.41904761
Subtracting 105 from 200 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

After the division, we end up with 762949.41904761 and a remainder of 9.5e-08.
