7 divided by 154 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 154

Step 2:
154 can be fit into 78 0 times, resulting in a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Grab the next digit (9) from the dividend, add it to 78, then carry on: 789 / 154

Let's proceed to step 3:
789 divided by 154 is 5 with a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 19 after subtracting 770 from 789.

On to step 4:
The number 154 fits into 191 1 times, leaving a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
The remainder is 37 after subtracting 154 from 191.
Fetch the next digit (7) from the dividend, attach it to 37 and continue: 377 / 154

Advancing to step 5:
If we divide 377 by 154, we get 2 and a remainder of 69.
Record the quotient 2 as the next digit in the result. 
Result so far: 512.0
Deduct 308 from 377 and we're left with 69.
Grab the next digit (6) from the dividend, add it to 69, then carry on: 696 / 154

Moving on to step 6:
696 divided by 154 is 4 with a remainder of 80.
The next digit of our result is 4. 
Result so far: 5124.0
If we subtract 616 from 696, we get 80.
Include the next digit (5) from the dividend after 80, then repeat: 805 / 154

Advancing to step 7:
154 goes into 805 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 51245.0
If we subtract 770 from 805, we get 35.
Fetch the next digit (5) from the dividend, attach it to 35 and continue: 355 / 154

On to step 8:
When dividing 355 by 154, we get 2 with a remainder of 47.
The next digit of our result is 2. 
Result so far: 512452.0
Subtract 308 from 355 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 9:
When dividing 470 by 154, we get 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 512452.3
Subtracting 462 from 470 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
When dividing 80 by 154, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 512452.3
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
800 divided by 154 is 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 512452.305
The remainder is 30 after subtracting 770 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
If we divide 300 by 154, we get 1 and a remainder of 146.
Put 1 as the next digit of the answer. 
Result so far: 512452.3051
If we subtract 154 from 300, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 13:
154 goes into 1460 9 times with a remainder of 74.
Use 9 as the next digit of our solution. 
Result so far: 512452.30519
If we take 1386 away from 1460, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 14:
740 divided by 154 is 4 with a remainder of 124.
Put 4 as the next digit of the answer. 
Result so far: 512452.305194
If we subtract 616 from 740, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 15:
154 goes into 1240 8 times with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 512452.3051948
If we take 1232 away from 1240, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 16:
154 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 512452.3051948
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 512452.3051948 with a remaining 8e-08.
