984021 divided by 51 
Our goal is to divide 984021 by 51.

Step 1:
If we divide 9 by 51, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 51

Moving on to step 2:
51 can be fit into 98 1 times, resulting in a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 51 from 98 leaves us with 47.
Grab the next digit (4) from the dividend, add it to 47, then carry on: 474 / 51

Advancing to step 3:
51 can be fit into 474 9 times, resulting in a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 459 from 474 and we're left with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 51

Moving on to step 4:
The number 51 fits into 150 2 times, leaving a remainder of 48.
The next digit of our result is 2. 
Result so far: 192.0
If we take 102 away from 150, we end up with 48.
Grab the next digit (2) from the dividend, add it to 48, then carry on: 482 / 51

Let's proceed to step 5:
482 divided by 51 is 9 with a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 1929.0
If we subtract 459 from 482, we get 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 51

Let's proceed to step 6:
If we divide 231 by 51, we get 4 and a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 19294.0
Subtract 204 from 231 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
51 can be fit into 270 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 19294.5
If we subtract 255 from 270, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
51 can be fit into 150 2 times, resulting in a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 19294.52
The remainder is 48 after subtracting 102 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
51 can be fit into 480 9 times, resulting in a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 19294.529
Deduct 459 from 480 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 10:
When dividing 210 by 51, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 19294.5294
Deduct 204 from 210 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
51 goes into 60 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 19294.52941
If we take 51 away from 60, we end up 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 12:
90 divided by 51 is 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 19294.529411
If we subtract 51 from 90, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Our division results in 19294.529411 with a remaining 3.9e-06.
