984209 divided by 51 
We want to figure out the number of times 984209 can be divided by 51.

Step 1:
9 divided by 51 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 51

Let's proceed to step 2:
51 can be fit into 98 1 times, resulting in a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 51 from 98, we get 47.
Take the next digit (4) from the dividend and append it to 47, then repeat: 474 / 51

Advancing to step 3:
The number 51 fits into 474 9 times, leaving a remainder of 15.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 15 after subtracting 459 from 474.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 51

Going ahead to step 4:
When dividing 152 by 51, we get 2 with a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 192.0
The remainder is 50 after subtracting 102 from 152.
Append the next digit (0) from the dividend to 50 and continue with: 500 / 51

Let's proceed to step 5:
The number 51 fits into 500 9 times, leaving a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 1929.0
If we take 459 away from 500, we end up with 41.
Grab the next digit (9) from the dividend, add it to 41, then carry on: 419 / 51

Advancing to step 6:
51 goes into 419 8 times with a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 19298.0
If we take 408 away from 419, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
51 goes into 110 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 19298.2
If we take 102 away from 110, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
If we divide 80 by 51, we get 1 and a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 19298.21
Deduct 51 from 80 and we're left with 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 9:
290 divided by 51 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 19298.215
Subtract 255 from 290 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 10:
51 goes into 350 6 times with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 19298.2156
The remainder is 44 after subtracting 306 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 11:
If we divide 440 by 51, we get 8 and a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 19298.21568
Subtract 408 from 440 to 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.

Moving on to step 12:
51 goes into 320 6 times with a remainder of 14.
The next digit of our result is 6. 
Result so far: 19298.215686
Subtracting 306 from 320 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 13:
If we divide 140 by 51, we get 2 and a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 19298.2156862
Subtracting 102 from 140 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
51 goes into 380 7 times with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 19298.21568627
Subtract 357 from 380 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 19298.21568627, with a leftover of 2.3e-08.
