43642218 ÷ 135 
We're looking to find how many times 135 goes into 43642218.

Let's proceed to step 1:
4 divided by 135 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 135

Going ahead to step 2:
135 can be fit into 43 0 times, resulting in 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.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 135

Moving on to step 3:
135 can be fit into 436 3 times, resulting in a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 405 from 436, we get 31.
Grab the next digit (4) from the dividend, add it to 31, then carry on: 314 / 135

On to step 4:
The number 135 fits into 314 2 times, leaving a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Subtract 270 from 314 to get 44.
Bring next digit (2) of the dividend behind the 44 and repeat the process: 442 / 135

Going ahead to step 5:
If we divide 442 by 135, we get 3 and a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 323.0
Deduct 405 from 442 and we're left with 37.
Grab the next digit (2) from the dividend, add it to 37, then carry on: 372 / 135

Going ahead to step 6:
135 goes into 372 2 times with a remainder of 102.
Record the quotient 2 as the next digit in the result. 
Result so far: 3232.0
Deduct 270 from 372 and we're left with 102.
Include the next digit (1) from the dividend after 102, then repeat: 1021 / 135

Advancing to step 7:
When dividing 1021 by 135, we get 7 with a remainder of 76.
Write down 7 as next digit of the result. 
Result so far: 32327.0
Subtracting 945 from 1021 leaves us with 76.
Fetch the next digit (8) from the dividend, attach it to 76 and continue: 768 / 135

Let's proceed to step 8:
When dividing 768 by 135, we get 5 with a remainder of 93.
Write down 5 as next digit of the result. 
Result so far: 323275.0
Subtracting 675 from 768 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 9:
If we divide 930 by 135, we get 6 and a remainder of 120.
Write down 6 as next digit of the result. 
Result so far: 323275.6
If we take 810 away from 930, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 10:
If we divide 1200 by 135, we get 8 and a remainder of 120.
Write down 8 as next digit of the result. 
Result so far: 323275.68
Deduct 1080 from 1200 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
If we divide 1200 by 135, we get 8 and a remainder of 120.
The number 8 becomes the next digit in our result. 
Result so far: 323275.688
Subtract 1080 from 1200 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final outcome is 323275.688, with a leftover of 0.012.
