690864 ÷ 43 
We're looking to find how many times 43 goes into 690864.

Step 1:
43 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 43

Let's proceed to step 2:
If we divide 69 by 43, we get 1 and a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 43 from 69 leaves us with 26.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 43

Advancing to step 3:
If we divide 260 by 43, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 258 from 260 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 43

Advancing to step 4:
If we divide 28 by 43, we get 0 and a remainder of 28.
The next digit of our result is 0. 
Result so far: 160.0
Subtracting 0 from 28 leaves us with 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 43

Going ahead to step 5:
43 can be fit into 286 6 times, resulting in a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 1606.0
Subtract 258 from 286 to get 28.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 43

On to step 6:
43 can be fit into 284 6 times, resulting in a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 16066.0
Deduct 258 from 284 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
260 divided by 43 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 16066.6
Deduct 258 from 260 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
43 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 16066.6
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
The number 43 fits into 200 4 times, leaving a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 16066.604
If we take 172 away from 200, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
43 can be fit into 280 6 times, resulting in a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 16066.6046
If we take 258 away from 280, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
43 can be fit into 220 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 16066.60465
Deduct 215 from 220 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
43 can be fit into 50 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 16066.604651
Subtract 43 from 50 to 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.

Advancing to step 13:
43 goes into 70 1 times with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 16066.6046511
If we take 43 away from 70, we end up 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.

After the division, we end up with 16066.6046511 and a remainder of 2.7e-07.
