Let's divide 991434 by 51
We want to divide 991434 by 51.

Let's proceed to step 1:
51 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 51

Step 2:
The number 51 fits into 99 1 times, leaving a remainder of 48.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 51 from 99, we get 48.
Append the next digit (1) from the dividend to 48 and continue with: 481 / 51

Let's proceed to step 3:
When dividing 481 by 51, we get 9 with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 459 from 481 to get 22.
Append the next digit (4) from the dividend to 22 and continue with: 224 / 51

Advancing to step 4:
If we divide 224 by 51, we get 4 and a remainder of 20.
The next digit of our result is 4. 
Result so far: 194.0
If we subtract 204 from 224, we get 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 51

Let's proceed to step 5:
203 divided by 51 is 3 with a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 1943.0
The remainder is 50 after subtracting 153 from 203.
Fetch the next digit (4) from the dividend, attach it to 50 and continue: 504 / 51

Let's proceed to step 6:
If we divide 504 by 51, we get 9 and a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 19439.0
Deduct 459 from 504 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 7:
The number 51 fits into 450 8 times, leaving a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 19439.8
Subtracting 408 from 450 leaves us 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.

Advancing to step 8:
51 goes into 420 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 19439.88
Deduct 408 from 420 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 19439.88, and the remainder is 0.012.
