We're dividing 142130 by 40 
We want to divide 142130 by 40.

Step 1:
If we divide 1 by 40, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 40

Step 2:
When dividing 14 by 40, we get 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 40

On to step 3:
40 can be fit into 142 3 times, resulting in a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 120 from 142, we get 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 40

On to step 4:
40 goes into 221 5 times with a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 35.0
If we subtract 200 from 221, we get 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 40

Let's proceed to step 5:
When dividing 213 by 40, we get 5 with a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 355.0
If we take 200 away from 213, we end up with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 40

Moving on to step 6:
130 divided by 40 is 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 3553.0
Subtract 120 from 130 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
When dividing 100 by 40, we get 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 3553.2
If we subtract 80 from 100, 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.

Going ahead to step 8:
40 goes into 200 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 3553.25
If we take 200 away from 200, 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.

On to step 9:
0 divided by 40 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3553.25
Subtracting 0 from 0 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.

Advancing to step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3553.25
Subtracting 0 from 0 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.

The quotient of the division is 3553.25, and the remainder is 0.0.
