670385 divided by 43 
We want to figure out the number of times 670385 can be divided 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
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 43

On to step 2:
When dividing 67 by 43, we get 1 with a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 24 after subtracting 43 from 67.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 43

On to step 3:
43 goes into 240 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 215 from 240 and we're left with 25.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 43

Advancing to step 4:
43 goes into 253 5 times with a remainder of 38.
Put 5 as the next digit of the answer. 
Result so far: 155.0
Subtract 215 from 253 to get 38.
Fetch the next digit (8) from the dividend, attach it to 38 and continue: 388 / 43

Step 5:
388 divided by 43 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 1559.0
Subtract 387 from 388 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 43

Advancing to step 6:
43 can be fit into 15 0 times, resulting in a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 15590.0
If we subtract 0 from 15, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
43 can be fit into 150 3 times, resulting in a remainder of 21.
The next digit of our result is 3. 
Result so far: 15590.3
The remainder is 21 after subtracting 129 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 8:
43 can be fit into 210 4 times, resulting in a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 15590.34
If we subtract 172 from 210, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
When dividing 380 by 43, we get 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 15590.348
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
The number 43 fits into 360 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 15590.3488
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 15590.3488 with a remaining 0.00016.
