We look at the division of 998589 by 51 
Let's see how many times 51 fits into 998589.

On to step 1:
9 divided by 51 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 51

Let's proceed to step 2:
When dividing 99 by 51, we get 1 with a remainder of 48.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 51 from 99 leaves us with 48.
Fetch the next digit (8) from the dividend, attach it to 48 and continue: 488 / 51

Moving on to step 3:
The number 51 fits into 488 9 times, leaving a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 459 from 488 and we're left with 29.
Fetch the next digit (5) from the dividend, attach it to 29 and continue: 295 / 51

Advancing to step 4:
If we divide 295 by 51, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 195.0
Deduct 255 from 295 and we're left with 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 51

Let's proceed to step 5:
When dividing 408 by 51, we get 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 1958.0
Deduct 408 from 408 and we're left with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 51

Moving on to step 6:
51 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 19580.0
Subtracting 0 from 9 leaves us 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.

Let's proceed to step 7:
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: 19580.1
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.

Advancing to step 8:
390 divided by 51 is 7 with a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 19580.17
Subtracting 357 from 390 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
When dividing 330 by 51, we get 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 19580.176
The remainder is 24 after subtracting 306 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
If we divide 240 by 51, we get 4 and a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 19580.1764
If we subtract 204 from 240, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
51 can be fit into 360 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 19580.17647
If we take 357 away from 360, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 12:
30 divided by 51 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 19580.17647
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
51 goes into 300 5 times with a remainder of 45.
The next digit of our result is 5. 
Result so far: 19580.1764705
Deduct 255 from 300 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 14:
51 can be fit into 450 8 times, resulting in a remainder of 42.
The next digit of our result is 8. 
Result so far: 19580.17647058
If we take 408 away from 450, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 19580.17647058 with a remaining 4.2e-08.
