We look at the division of 900154 by 51 
Let's see how many times 51 fits into 900154.

On to step 1:
The number 51 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 51

Moving on to step 2:
51 can be fit into 90 1 times, resulting in a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 51 from 90, we get 39.
Fetch the next digit (0) from the dividend, attach it to 39 and continue: 390 / 51

On to step 3:
When dividing 390 by 51, we get 7 with a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 357 away from 390, we end up with 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 51

Step 4:
51 can be fit into 331 6 times, resulting in a remainder of 25.
The next digit of our result is 6. 
Result so far: 176.0
If we subtract 306 from 331, we get 25.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 51

Moving on to step 5:
The number 51 fits into 255 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1765.0
Deduct 255 from 255 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 51

Advancing to step 6:
The number 51 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 17650.0
The remainder is 4 after subtracting 0 from 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
When dividing 40 by 51, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 17650.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
The number 51 fits into 400 7 times, leaving a remainder of 43.
The next digit of our result is 7. 
Result so far: 17650.07
The remainder is 43 after subtracting 357 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
51 goes into 430 8 times with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 17650.078
Deduct 408 from 430 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
The number 51 fits into 220 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 17650.0784
The remainder is 16 after subtracting 204 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
The number 51 fits into 160 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 17650.07843
Deduct 153 from 160 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 12:
51 goes into 70 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 17650.078431
The remainder is 19 after subtracting 51 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 13:
51 can be fit into 190 3 times, resulting in a remainder of 37.
The next digit of our result is 3. 
Result so far: 17650.0784313
Subtracting 153 from 190 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 14:
51 can be fit into 370 7 times, resulting in a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 17650.07843137
Subtract 357 from 370 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 17650.07843137 and a remainder of 1.3e-08.
