We're dividing 361638 by 43 
We're looking to find how many times 43 goes into 361638.

Going ahead to step 1:
If we divide 3 by 43, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 43

Moving on to step 2:
The number 43 fits into 36 0 times, leaving a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 36 to get 36.
Include the next digit (1) from the dividend after 36, then repeat: 361 / 43

Advancing to step 3:
43 goes into 361 8 times with a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 17 after subtracting 344 from 361.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 43

Step 4:
43 goes into 176 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 84.0
If we take 172 away from 176, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 43

Advancing to step 5:
When dividing 43 by 43, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 841.0
Deduct 43 from 43 and we're left with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 43

Let's proceed to step 6:
8 divided by 43 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 8410.0
Subtracting 0 from 8 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
43 can be fit into 80 1 times, resulting in a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 8410.1
Subtract 43 from 80 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 8:
370 divided by 43 is 8 with a remainder of 26.
The next digit of our result is 8. 
Result so far: 8410.18
Deduct 344 from 370 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.

Step 9:
If we divide 260 by 43, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 8410.186
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.

On to step 10:
43 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 8410.186
If we subtract 0 from 20, we get 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 11:
The number 43 fits into 200 4 times, leaving a remainder of 28.
The next digit of our result is 4. 
Result so far: 8410.18604
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.

Going ahead to step 12:
If we divide 280 by 43, we get 6 and a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 8410.186046
Subtracting 258 from 280 leaves us 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 13:
If we divide 220 by 43, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 8410.1860465
If we take 215 away from 220, we end up 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.

Going ahead to step 14:
43 can be fit into 50 1 times, resulting in a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 8410.18604651
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.

The final result is 8410.18604651 with a remainder of 7e-09.
