Let's divide 143658 by 40
Let's see how many times 40 fits into 143658.

On to step 1:
40 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 40

Moving on to step 2:
The number 40 fits into 14 0 times, leaving a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 40

Advancing to step 3:
143 divided by 40 is 3 with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 120 from 143 leaves us with 23.
Append the next digit (6) from the dividend to 23 and continue with: 236 / 40

Step 4:
If we divide 236 by 40, we get 5 and a remainder of 36.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we subtract 200 from 236, we get 36.
Include the next digit (5) from the dividend after 36, then repeat: 365 / 40

Let's proceed to step 5:
40 can be fit into 365 9 times, resulting in a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 359.0
Subtract 360 from 365 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 40

On to step 6:
40 goes into 58 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 3591.0
Deduct 40 from 58 and we're left 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.

Advancing to step 7:
40 goes into 180 4 times with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 3591.4
Deduct 160 from 180 and we're left 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.

Advancing to step 8:
200 divided by 40 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 3591.45
Subtracting 200 from 200 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3591.45
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
When dividing 0 by 40, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3591.45
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 3591.45 with a remainder of 0.0.
