We look at the division of 684991 by 43 
We're looking to find how many times 43 goes into 684991.

Moving on to step 1:
43 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 43

Moving on to step 2:
68 divided by 43 is 1 with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 43 from 68 leaves us with 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 43

Going ahead to step 3:
The number 43 fits into 254 5 times, leaving a remainder of 39.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 215 from 254, we get 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 43

Step 4:
When dividing 399 by 43, we get 9 with a remainder of 12.
The next digit of our result is 9. 
Result so far: 159.0
Subtracting 387 from 399 leaves us with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 43

Let's proceed to step 5:
129 divided by 43 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 1593.0
If we subtract 129 from 129, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 43

Let's proceed to step 6:
43 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 15930.0
Deduct 0 from 1 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
43 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 15930.0
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 8:
If we divide 100 by 43, we get 2 and a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 15930.02
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
43 can be fit into 140 3 times, resulting in a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 15930.023
The remainder is 11 after subtracting 129 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
If we divide 110 by 43, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 15930.0232
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.

Advancing to step 11:
If we divide 240 by 43, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 15930.02325
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 12:
43 goes into 250 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 15930.023255
Subtracting 215 from 250 leaves us with 35.
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 15930.023255 with a remainder of 3.5e-06.
