We're dividing 121470 by 51 
Let's see how many times 51 fits into 121470.

Advancing to step 1:
51 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 51

Advancing to step 2:
12 divided by 51 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 51

Moving on to step 3:
The number 51 fits into 121 2 times, leaving a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 102 from 121, we get 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 51

Moving on to step 4:
The number 51 fits into 194 3 times, leaving a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we take 153 away from 194, we end up with 41.
Append the next digit (7) from the dividend to 41 and continue with: 417 / 51

Advancing to step 5:
51 goes into 417 8 times with a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 238.0
Deduct 408 from 417 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 51

Advancing to step 6:
The number 51 fits into 90 1 times, leaving a remainder of 39.
The next digit of our result is 1. 
Result so far: 2381.0
Subtract 51 from 90 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
51 goes into 390 7 times with a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 2381.7
Subtracting 357 from 390 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 8:
If we divide 330 by 51, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 2381.76
If we subtract 306 from 330, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
When dividing 240 by 51, we get 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 2381.764
If we subtract 204 from 240, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
360 divided by 51 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 2381.7647
If we take 357 away from 360, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 11:
30 divided by 51 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 2381.7647
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
300 divided by 51 is 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 2381.764705
Subtract 255 from 300 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 13:
51 goes into 450 8 times with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 2381.7647058
Deduct 408 from 450 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 14:
When dividing 420 by 51, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 2381.76470588
Subtract 408 from 420 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 2381.76470588 with a remaining 1.2e-08.
