We look at the division of 986921 by 51 
We want to divide 986921 by 51.

Advancing to step 1:
51 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
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

Moving on to step 2:
98 divided by 51 is 1 with a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 51 from 98, we get 47.
Include the next digit (6) from the dividend after 47, then repeat: 476 / 51

Moving on to step 3:
51 can be fit into 476 9 times, resulting in a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 459 from 476 leaves us with 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 51

Advancing to step 4:
51 goes into 179 3 times with a remainder of 26.
The next digit of our result is 3. 
Result so far: 193.0
Subtract 153 from 179 to get 26.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 51

Going ahead to step 5:
When dividing 262 by 51, we get 5 with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 1935.0
Deduct 255 from 262 and we're left with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 51

Let's proceed to step 6:
71 divided by 51 is 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 19351.0
The remainder is 20 after subtracting 51 from 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
51 goes into 200 3 times with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 19351.3
Subtract 153 from 200 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 8:
51 can be fit into 470 9 times, resulting in a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 19351.39
Deduct 459 from 470 and we're left 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.

Going ahead to step 9:
110 divided by 51 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 19351.392
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.

Step 10:
If we divide 80 by 51, we get 1 and a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 19351.3921
If we take 51 away from 80, we end up 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.

Let's proceed to step 11:
When dividing 290 by 51, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 19351.39215
The remainder is 35 after subtracting 255 from 290.
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 12:
The number 51 fits into 350 6 times, leaving a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 19351.392156
If we subtract 306 from 350, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 13:
When dividing 440 by 51, we get 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 19351.3921568
Subtracting 408 from 440 leaves us with 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 14:
When dividing 320 by 51, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 19351.39215686
The remainder is 14 after subtracting 306 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 19351.39215686 with a balance of 1.4e-08.
