Let's divide 86743843 by 109
Let's see how many times 109 fits into 86743843.

Advancing to step 1:
The number 109 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 109

Going ahead to step 2:
86 divided by 109 is 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Bring next digit (7) of the dividend behind the 86 and repeat the process: 867 / 109

Going ahead to step 3:
109 goes into 867 7 times with a remainder of 104.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 763 from 867 to get 104.
Take the next digit (4) from the dividend and append it to 104, then repeat: 1044 / 109

On to step 4:
109 can be fit into 1044 9 times, resulting in a remainder of 63.
Write down 9 as next digit of the result. 
Result so far: 79.0
Subtract 981 from 1044 to get 63.
Append the next digit (3) from the dividend to 63 and continue with: 633 / 109

Moving on to step 5:
When dividing 633 by 109, we get 5 with a remainder of 88.
Write down 5 as next digit of the result. 
Result so far: 795.0
The remainder is 88 after subtracting 545 from 633.
Take the next digit (8) from the dividend and append it to 88, then repeat: 888 / 109

Step 6:
109 can be fit into 888 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 7958.0
The remainder is 16 after subtracting 872 from 888.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 109

On to step 7:
When dividing 164 by 109, we get 1 with a remainder of 55.
The number 1 becomes the next digit in our result. 
Result so far: 79581.0
Subtracting 109 from 164 leaves us with 55.
Bring next digit (3) of the dividend behind the 55 and repeat the process: 553 / 109

Step 8:
109 can be fit into 553 5 times, resulting in a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 795815.0
Deduct 545 from 553 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
When dividing 80 by 109, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 795815.0
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
If we divide 800 by 109, we get 7 and a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 795815.07
The remainder is 37 after subtracting 763 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 11:
If we divide 370 by 109, we get 3 and a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 795815.073
If we subtract 327 from 370, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 12:
109 can be fit into 430 3 times, resulting in a remainder of 103.
Use 3 as the next digit of our solution. 
Result so far: 795815.0733
If we subtract 327 from 430, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

After the division, we end up with 795815.0733 and a remainder of 0.00103.
