261640 divided by 43 
We want to figure out the number of times 261640 can be divided by 43.

Step 1:
2 divided by 43 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 43

Let's proceed to step 2:
43 goes into 26 0 times with a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 26, we end up with 26.
Grab the next digit (1) from the dividend, add it to 26, then carry on: 261 / 43

Advancing to step 3:
43 can be fit into 261 6 times, resulting in a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 258 from 261 to get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 43

Advancing to step 4:
43 goes into 36 0 times with a remainder of 36.
The next digit of our result is 0. 
Result so far: 60.0
If we subtract 0 from 36, we get 36.
Fetch the next digit (4) from the dividend, attach it to 36 and continue: 364 / 43

Moving on to step 5:
If we divide 364 by 43, we get 8 and a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 608.0
If we subtract 344 from 364, we get 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 43

On to step 6:
When dividing 200 by 43, we get 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 6084.0
Subtract 172 from 200 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
43 goes into 280 6 times with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 6084.6
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.

Step 8:
43 can be fit into 220 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 6084.65
Subtract 215 from 220 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
The number 43 fits into 50 1 times, leaving a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 6084.651
If we take 43 away from 50, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
43 can be fit into 70 1 times, resulting in a remainder of 27.
The next digit of our result is 1. 
Result so far: 6084.6511
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.

Our division results in 6084.6511 with a remaining 0.00027.
