Let's divide 86350807 by 43
Our goal is to divide 86350807 by 43.

Step 1:
43 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 43

Moving on to step 2:
43 goes into 86 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 86 from 86 to get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 43

On to step 3:
When dividing 3 by 43, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 43

On to step 4:
When dividing 35 by 43, we get 0 with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 200.0
If we take 0 away from 35, we end up with 35.
Include the next digit (0) from the dividend after 35, then repeat: 350 / 43

Going ahead to step 5:
43 goes into 350 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 2008.0
Deduct 344 from 350 and we're left with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 43

Advancing to step 6:
68 divided by 43 is 1 with a remainder of 25.
The next digit of our result is 1. 
Result so far: 20081.0
Subtract 43 from 68 to get 25.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 43

On to step 7:
If we divide 250 by 43, we get 5 and a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 200815.0
If we subtract 215 from 250, we get 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 43

Advancing to step 8:
If we divide 357 by 43, we get 8 and a remainder of 13.
The next digit of our result is 8. 
Result so far: 2008158.0
If we take 344 away from 357, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
The number 43 fits into 130 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 2008158.3
Subtract 129 from 130 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
If we divide 10 by 43, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 2008158.3
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
If we divide 100 by 43, we get 2 and a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 2008158.302
If we subtract 86 from 100, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
The number 43 fits into 140 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 2008158.3023
Subtracting 129 from 140 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 13:
110 divided by 43 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 2008158.30232
If we take 86 away from 110, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
When dividing 240 by 43, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 2008158.302325
If we take 215 away from 240, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 15:
43 goes into 250 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 2008158.3023255
The remainder is 35 after subtracting 215 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 2008158.3023255 with a remainder of 3.5e-07.
