We look at the division of 980343 by 51 
Our goal is to divide 980343 by 51.

Moving on to step 1:
51 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 51

Step 2:
If we divide 98 by 51, we get 1 and a remainder of 47.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 51 from 98, we get 47.
Include the next digit (0) from the dividend after 47, then repeat: 470 / 51

Let's proceed to step 3:
470 divided by 51 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 459 from 470 and we're left with 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 51

Step 4:
The number 51 fits into 113 2 times, leaving a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 192.0
If we take 102 away from 113, we end up with 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 51

Step 5:
114 divided by 51 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 1922.0
If we subtract 102 from 114, we get 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 51

Step 6:
51 can be fit into 123 2 times, resulting in a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 19222.0
Deduct 102 from 123 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.

Step 7:
51 can be fit into 210 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 19222.4
If we take 204 away from 210, we end up 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.

Advancing to step 8:
60 divided by 51 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 19222.41
If we subtract 51 from 60, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
90 divided by 51 is 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 19222.411
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 outcome is 19222.411, with a leftover of 0.0039.
