Let's divide 43179993 by 261
Our goal is to divide 43179993 by 261.

Step 1:
261 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 261

Step 2:
When dividing 43 by 261, we get 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 261

Moving on to step 3:
261 goes into 431 1 times with a remainder of 170.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 170 after subtracting 261 from 431.
Grab the next digit (7) from the dividend, add it to 170, then carry on: 1707 / 261

Step 4:
261 can be fit into 1707 6 times, resulting in a remainder of 141.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 141 after subtracting 1566 from 1707.
Bring next digit (9) of the dividend behind the 141 and repeat the process: 1419 / 261

On to step 5:
If we divide 1419 by 261, we get 5 and a remainder of 114.
Use 5 as the next digit of our solution. 
Result so far: 165.0
Subtracting 1305 from 1419 leaves us with 114.
Take the next digit (9) from the dividend and append it to 114, then repeat: 1149 / 261

Step 6:
When dividing 1149 by 261, we get 4 with a remainder of 105.
Write down 4 as next digit of the result. 
Result so far: 1654.0
If we subtract 1044 from 1149, we get 105.
Include the next digit (9) from the dividend after 105, then repeat: 1059 / 261

Advancing to step 7:
261 can be fit into 1059 4 times, resulting in a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 16544.0
Subtracting 1044 from 1059 leaves us with 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 261

Going ahead to step 8:
153 divided by 261 is 0 with a remainder of 153.
The next digit of our result is 0. 
Result so far: 165440.0
If we take 0 away from 153, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Going ahead to step 9:
The number 261 fits into 1530 5 times, leaving a remainder of 225.
Put 5 as the next digit of the answer. 
Result so far: 165440.5
The remainder is 225 after subtracting 1305 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 10:
261 goes into 2250 8 times with a remainder of 162.
Write down 8 as next digit of the result. 
Result so far: 165440.58
Deduct 2088 from 2250 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 11:
The number 261 fits into 1620 6 times, leaving a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 165440.586
If we subtract 1566 from 1620, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 12:
When dividing 540 by 261, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 165440.5862
Subtracting 522 from 540 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
If we divide 180 by 261, we get 0 and a remainder of 180.
The next digit of our result is 0. 
Result so far: 165440.5862
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 14:
The number 261 fits into 1800 6 times, leaving a remainder of 234.
Record the quotient 6 as the next digit in the result. 
Result so far: 165440.586206
The remainder is 234 after subtracting 1566 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Let's proceed to step 15:
261 goes into 2340 8 times with a remainder of 252.
Put 8 as the next digit of the answer. 
Result so far: 165440.5862068
Subtracting 2088 from 2340 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 16:
261 goes into 2520 9 times with a remainder of 171.
The next digit of our result is 9. 
Result so far: 165440.58620689
The remainder is 171 after subtracting 2349 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

After the division, we end up with 165440.58620689 and a remainder of 1.71e-07.
