Let's divide 978409 by 51
We want to divide 978409 by 51.

Let's proceed to step 1:
51 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 51

Advancing 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
Subtract 51 from 97 to get 46.
Bring next digit (8) of the dividend behind the 46 and repeat the process: 468 / 51

Going ahead to step 3:
51 can be fit into 468 9 times, resulting in a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 459 from 468 and we're left with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 51

Moving on to step 4:
The number 51 fits into 94 1 times, leaving a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 191.0
If we subtract 51 from 94, we get 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 51

Let's proceed to step 5:
430 divided by 51 is 8 with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 1918.0
The remainder is 22 after subtracting 408 from 430.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 51

Moving on to step 6:
51 can be fit into 229 4 times, resulting in a remainder of 25.
Use 4 as the next digit of our solution. 
Result so far: 19184.0
Subtract 204 from 229 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
250 divided by 51 is 4 with a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 19184.4
The remainder is 46 after subtracting 204 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 8:
51 can be fit into 460 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 19184.49
Subtract 459 from 460 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
When dividing 10 by 51, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 19184.49
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
If we divide 100 by 51, we get 1 and a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 19184.4901
Deduct 51 from 100 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 11:
51 goes into 490 9 times with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 19184.49019
If we take 459 away from 490, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 12:
If we divide 310 by 51, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 19184.490196
If we take 306 away from 310, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
If we divide 40 by 51, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 19184.490196
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
400 divided by 51 is 7 with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 19184.49019607
Subtracting 357 from 400 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The final result is 19184.49019607 with a remainder of 4.3e-08.
