Let's divide 409198 by 40
We're looking to find how many times 40 goes into 409198.

Step 1:
If we divide 4 by 40, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 40

Advancing to step 2:
40 can be fit into 40 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 0 after subtracting 40 from 40.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 40

Advancing to step 3:
When dividing 9 by 40, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 9 to get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 40

On to step 4:
40 goes into 91 2 times with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 102.0
Deduct 80 from 91 and we're left with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 40

Advancing to step 5:
119 divided by 40 is 2 with a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 1022.0
If we take 80 away from 119, we end up with 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 40

Moving on to step 6:
40 goes into 398 9 times with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 10229.0
Subtract 360 from 398 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 7:
When dividing 380 by 40, we get 9 with a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 10229.9
Subtracting 360 from 380 leaves us 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:
If we divide 200 by 40, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10229.95
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.

Moving on to step 9:
The number 40 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 10229.95
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.

Advancing to step 10:
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: 10229.95
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.

After the division, we end up with 10229.95 and a remainder of 0.0.
