We divide 121757 by 51
We want to figure out the number of times 121757 can be divided by 51.

Let's proceed to step 1:
51 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 51

Moving on to step 2:
If we divide 12 by 51, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 51

On to step 3:
51 goes into 121 2 times with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 102 from 121 leaves us with 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 51

Step 4:
197 divided by 51 is 3 with a remainder of 44.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtract 153 from 197 to get 44.
Include the next digit (5) from the dividend after 44, then repeat: 445 / 51

Advancing to step 5:
If we divide 445 by 51, we get 8 and a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 238.0
The remainder is 37 after subtracting 408 from 445.
Fetch the next digit (7) from the dividend, attach it to 37 and continue: 377 / 51

On to step 6:
377 divided by 51 is 7 with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 2387.0
Subtracting 357 from 377 leaves us 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 7:
51 can be fit into 200 3 times, resulting in a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 2387.3
The remainder is 47 after subtracting 153 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 8:
When dividing 470 by 51, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 2387.39
Subtracting 459 from 470 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
110 divided by 51 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 2387.392
Subtract 102 from 110 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
When dividing 80 by 51, we get 1 with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 2387.3921
If we take 51 away from 80, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 11:
51 can be fit into 290 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 2387.39215
Subtracting 255 from 290 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 12:
51 goes into 350 6 times with a remainder of 44.
The next digit of our result is 6. 
Result so far: 2387.392156
Deduct 306 from 350 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 13:
51 goes into 440 8 times with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 2387.3921568
Subtracting 408 from 440 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
If we divide 320 by 51, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 2387.39215686
Subtracting 306 from 320 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 2387.39215686 with a remaining 1.4e-08.
