We divide 74439 by 51
Let's see how many times 51 fits into 74439.

Step 1:
If we divide 7 by 51, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 51

On to step 2:
51 can be fit into 74 1 times, resulting in a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 51 away from 74, we end up with 23.
Include the next digit (4) from the dividend after 23, then repeat: 234 / 51

On to step 3:
If we divide 234 by 51, we get 4 and a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 204 from 234 leaves us with 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 51

Going ahead to step 4:
The number 51 fits into 303 5 times, leaving a remainder of 48.
The next digit of our result is 5. 
Result so far: 145.0
The remainder is 48 after subtracting 255 from 303.
Append the next digit (9) from the dividend to 48 and continue with: 489 / 51

On to step 5:
51 can be fit into 489 9 times, resulting in a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 1459.0
Subtracting 459 from 489 leaves us 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 6:
51 goes into 300 5 times with a remainder of 45.
The next digit of our result is 5. 
Result so far: 1459.5
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.

Let's proceed to step 7:
51 goes into 450 8 times with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 1459.58
The remainder is 42 after subtracting 408 from 450.
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 8:
If we divide 420 by 51, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 1459.588
If we take 408 away from 420, we end up 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 final outcome is 1459.588, with a leftover of 0.0012.
