We're dividing 555154 by 40 
We want to figure out the number of times 555154 can be divided by 40.

Going ahead to step 1:
40 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 40

Advancing to step 2:
The number 40 fits into 55 1 times, leaving a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 15 after subtracting 40 from 55.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 40

Going ahead to step 3:
40 can be fit into 155 3 times, resulting in a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 35 after subtracting 120 from 155.
Bring next digit (1) of the dividend behind the 35 and repeat the process: 351 / 40

Advancing to step 4:
40 can be fit into 351 8 times, resulting in a remainder of 31.
Put 8 as the next digit of the answer. 
Result so far: 138.0
Deduct 320 from 351 and we're left with 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 40

Going ahead to step 5:
When dividing 315 by 40, we get 7 with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 1387.0
If we take 280 away from 315, we end up with 35.
Include the next digit (4) from the dividend after 35, then repeat: 354 / 40

Moving on to step 6:
40 can be fit into 354 8 times, resulting in a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 13878.0
The remainder is 34 after subtracting 320 from 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
340 divided by 40 is 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 13878.8
If we take 320 away from 340, 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.

Step 8:
40 goes into 200 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 13878.85
If we subtract 200 from 200, 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.

Let's proceed to step 9:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13878.85
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.

Advancing to step 10:
40 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13878.85
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 13878.85 with a remaining 0.0.
