We're dividing 43190 by 51 
Let's see how many times 51 fits into 43190.

Step 1:
4 divided by 51 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 51

Going ahead to step 2:
51 can be fit into 43 0 times, resulting in a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Include the next digit (1) from the dividend after 43, then repeat: 431 / 51

Going ahead to step 3:
51 can be fit into 431 8 times, resulting in a remainder of 23.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 408 from 431, we get 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 51

Let's proceed to step 4:
The number 51 fits into 239 4 times, leaving a remainder of 35.
The next digit of our result is 4. 
Result so far: 84.0
If we subtract 204 from 239, we get 35.
Include the next digit (0) from the dividend after 35, then repeat: 350 / 51

Moving on to step 5:
51 goes into 350 6 times with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 846.0
The remainder is 44 after subtracting 306 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 6:
When dividing 440 by 51, we get 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 846.8
Subtract 408 from 440 to get 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 7:
When dividing 320 by 51, we get 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 846.86
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.

Step 8:
140 divided by 51 is 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 846.862
If we subtract 102 from 140, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
51 can be fit into 380 7 times, resulting in a remainder of 23.
The next digit of our result is 7. 
Result so far: 846.8627
If we subtract 357 from 380, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 10:
51 can be fit into 230 4 times, resulting in a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 846.86274
If we subtract 204 from 230, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
260 divided by 51 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 846.862745
If we take 255 away from 260, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
51 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 846.862745
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
500 divided by 51 is 9 with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 846.86274509
Deduct 459 from 500 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Our division results in 846.86274509 with a remaining 4.1e-08.
