645093 divided by 43 
We want to divide 645093 by 43.

On to step 1:
If we divide 6 by 43, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 43

On to step 2:
The number 43 fits into 64 1 times, leaving a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 43 from 64, we get 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 43

Going ahead to step 3:
43 goes into 215 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 215 from 215, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 43

Moving on to step 4:
43 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
If we take 0 away from 0, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 43

Step 5:
43 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 1500.0
If we subtract 0 from 9, we get 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 43

Going ahead to step 6:
When dividing 93 by 43, we get 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 15002.0
If we subtract 86 from 93, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
The number 43 fits into 70 1 times, leaving a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 15002.1
Deduct 43 from 70 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 8:
43 goes into 270 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 15002.16
If we subtract 258 from 270, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
43 can be fit into 120 2 times, resulting in a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 15002.162
The remainder is 34 after subtracting 86 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
43 goes into 340 7 times with a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 15002.1627
Subtract 301 from 340 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 11:
The number 43 fits into 390 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 15002.16279
If we take 387 away from 390, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
43 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 15002.16279
If we take 0 away from 30, 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.

Step 13:
When dividing 300 by 43, we get 6 with a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 15002.1627906
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 14:
420 divided by 43 is 9 with a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 15002.16279069
Subtracting 387 from 420 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final outcome is 15002.16279069, with a leftover of 3.3e-08.
