We divide 151025 by 40
We want to divide 151025 by 40.

Going ahead to step 1:
If we divide 1 by 40, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 40

Moving on to step 2:
If we divide 15 by 40, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 40

Step 3:
151 divided by 40 is 3 with a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 120 from 151, we get 31.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 40

Let's proceed to step 4:
40 can be fit into 310 7 times, resulting in a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtract 280 from 310 to get 30.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 40

Moving on to step 5:
When dividing 302 by 40, we get 7 with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 377.0
If we take 280 away from 302, we end up with 22.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 40

On to step 6:
225 divided by 40 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 3775.0
The remainder is 25 after subtracting 200 from 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
250 divided by 40 is 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 3775.6
If we subtract 240 from 250, we 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.

On to step 8:
The number 40 fits into 100 2 times, leaving a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 3775.62
If we take 80 away from 100, we end up 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.

Moving on to step 9:
The number 40 fits into 200 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 3775.625
The remainder is 0 after subtracting 200 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
If we divide 0 by 40, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3775.625
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.

Step 11:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3775.625
Subtract 0 from 0 to 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 quotient of the division is 3775.625, and the remainder is 0.0.
