We look at the division of 680070 by 43 
We want to figure out the number of times 680070 can be divided by 43.

Step 1:
The number 43 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 43

Moving on to step 2:
When dividing 68 by 43, we get 1 with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 43 from 68 to get 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 43

Let's proceed to step 3:
43 can be fit into 250 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 215 from 250 and we're left with 35.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 43

On to step 4:
43 can be fit into 350 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
If we take 344 away from 350, we end up with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 43

Let's proceed to step 5:
If we divide 67 by 43, we get 1 and a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 1581.0
Subtract 43 from 67 to get 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 43

Advancing to step 6:
When dividing 240 by 43, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 15815.0
Deduct 215 from 240 and we're left 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.

Step 7:
43 can be fit into 250 5 times, resulting in a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 15815.5
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.

On to step 8:
350 divided by 43 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 15815.58
Subtracting 344 from 350 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
When dividing 60 by 43, we get 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 15815.581
If we subtract 43 from 60, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
If we divide 170 by 43, we get 3 and a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 15815.5813
If we take 129 away from 170, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 11:
If we divide 410 by 43, we get 9 and a remainder of 23.
The next digit of our result is 9. 
Result so far: 15815.58139
If we take 387 away from 410, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 12:
If we divide 230 by 43, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 15815.581395
Subtract 215 from 230 to 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.

Step 13:
When dividing 150 by 43, we get 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 15815.5813953
Deduct 129 from 150 and we're left with 21.
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 14:
210 divided by 43 is 4 with a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 15815.58139534
Deduct 172 from 210 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 15815.58139534 with a remaining 3.8e-08.
