Let's divide 978609 by 51
We want to divide 978609 by 51.

Step 1:
51 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 51

Let's proceed to step 2:
If we divide 97 by 51, we get 1 and a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 51 away from 97, we end up with 46.
Grab the next digit (8) from the dividend, add it to 46, then carry on: 468 / 51

Step 3:
When dividing 468 by 51, we get 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 459 from 468 to get 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 51

Going ahead to step 4:
96 divided by 51 is 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 191.0
Deduct 51 from 96 and we're left with 45.
Grab the next digit (0) from the dividend, add it to 45, then carry on: 450 / 51

Let's proceed to step 5:
When dividing 450 by 51, we get 8 with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 1918.0
Deduct 408 from 450 and we're left with 42.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 51

On to step 6:
When dividing 429 by 51, we get 8 with a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 19188.0
The remainder is 21 after subtracting 408 from 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
210 divided by 51 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 19188.4
The remainder is 6 after subtracting 204 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
51 goes into 60 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 19188.41
Deduct 51 from 60 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
When dividing 90 by 51, we get 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 19188.411
Subtracting 51 from 90 leaves us 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.

The final result is 19188.411 with a remainder of 0.0039.
