We're dividing 51225 by 43 
Let's see how many times 43 fits into 51225.

Going ahead to step 1:
5 divided by 43 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 43

Advancing to step 2:
43 goes into 51 1 times with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 43 from 51 to get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 43

Let's proceed to step 3:
43 can be fit into 82 1 times, resulting in a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 39 after subtracting 43 from 82.
Fetch the next digit (2) from the dividend, attach it to 39 and continue: 392 / 43

Step 4:
The number 43 fits into 392 9 times, leaving a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 119.0
The remainder is 5 after subtracting 387 from 392.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 43

On to step 5:
If we divide 55 by 43, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1191.0
If we subtract 43 from 55, we 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.

Step 6:
43 goes into 120 2 times with a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 1191.2
The remainder is 34 after subtracting 86 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
When dividing 340 by 43, we get 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 1191.27
Deduct 301 from 340 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 8:
If we divide 390 by 43, we get 9 and a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 1191.279
Subtracting 387 from 390 leaves us 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 9:
30 divided by 43 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 1191.279
Deduct 0 from 30 and we're left 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.

Advancing to step 10:
43 can be fit into 300 6 times, resulting in a remainder of 42.
The next digit of our result is 6. 
Result so far: 1191.27906
Deduct 258 from 300 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.

Step 11:
When dividing 420 by 43, we get 9 with a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 1191.279069
Deduct 387 from 420 and we're left 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.

Going ahead to step 12:
43 can be fit into 330 7 times, resulting in a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 1191.2790697
Subtract 301 from 330 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 13:
290 divided by 43 is 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 1191.27906976
If we subtract 258 from 290, we 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.

The quotient of the division is 1191.27906976, and the remainder is 3.2e-08.
