We look at the division of 622129 by 40 
Let's see how many times 40 fits into 622129.

On to step 1:
40 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 40

On to step 2:
The number 40 fits into 62 1 times, leaving a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 40 from 62, we get 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 40

Step 3:
40 goes into 222 5 times with a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 200 from 222 and we're left with 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 40

Step 4:
40 can be fit into 221 5 times, resulting in a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 155.0
The remainder is 21 after subtracting 200 from 221.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 40

Moving on to step 5:
40 goes into 212 5 times with a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 1555.0
Deduct 200 from 212 and we're left with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 40

Step 6:
The number 40 fits into 129 3 times, leaving a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 15553.0
The remainder is 9 after subtracting 120 from 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
If we divide 90 by 40, we get 2 and a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 15553.2
Subtract 80 from 90 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.

Moving on to step 8:
40 can be fit into 100 2 times, resulting in a remainder of 20.
The next digit of our result is 2. 
Result so far: 15553.22
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.

After the division, we end up with 15553.22 and a remainder of 0.02.
