Let's divide 154951 by 51
Let's see how many times 51 fits into 154951.

Advancing to step 1:
If we divide 1 by 51, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 51

Advancing to step 2:
The number 51 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 51

On to step 3:
If we divide 154 by 51, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 153 from 154, we get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 51

Step 4:
If we divide 19 by 51, we get 0 and a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we take 0 away from 19, we end up with 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 51

Going ahead to step 5:
When dividing 195 by 51, we get 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 303.0
The remainder is 42 after subtracting 153 from 195.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 51

Going ahead to step 6:
When dividing 421 by 51, we get 8 with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 3038.0
Subtract 408 from 421 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.

Step 7:
If we divide 130 by 51, we get 2 and a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 3038.2
Subtract 102 from 130 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 8:
When dividing 280 by 51, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 3038.25
If we subtract 255 from 280, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
When dividing 250 by 51, we get 4 with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 3038.254
If we subtract 204 from 250, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
The number 51 fits into 460 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 3038.2549
If we subtract 459 from 460, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
51 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 3038.2549
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
When dividing 100 by 51, we get 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 3038.254901
Deduct 51 from 100 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 13:
51 goes into 490 9 times with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 3038.2549019
If we take 459 away from 490, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 14:
If we divide 310 by 51, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 3038.25490196
The remainder is 4 after subtracting 306 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 3038.25490196 with a remaining 4e-09.
