We're dividing 84386 by 51 
Let's see how many times 51 fits into 84386.

Going ahead to step 1:
8 divided by 51 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 51

On to step 2:
The number 51 fits into 84 1 times, leaving a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 51 from 84, we get 33.
Bring next digit (3) of the dividend behind the 33 and repeat the process: 333 / 51

Going ahead to step 3:
51 can be fit into 333 6 times, resulting in a remainder of 27.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 306 from 333 and we're left with 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 51

Going ahead to step 4:
The number 51 fits into 278 5 times, leaving a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 165.0
The remainder is 23 after subtracting 255 from 278.
Bring next digit (6) of the dividend behind the 23 and repeat the process: 236 / 51

On to step 5:
If we divide 236 by 51, we get 4 and a remainder of 32.
The next digit of our result is 4. 
Result so far: 1654.0
If we subtract 204 from 236, we 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.

Going ahead to step 6:
320 divided by 51 is 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 1654.6
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.

Moving on to step 7:
When dividing 140 by 51, we get 2 with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 1654.62
Subtract 102 from 140 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 8:
The number 51 fits into 380 7 times, leaving a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 1654.627
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.

Step 9:
The number 51 fits into 230 4 times, leaving a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 1654.6274
If we subtract 204 from 230, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
51 goes into 260 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1654.62745
The remainder is 5 after subtracting 255 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
The number 51 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 1654.62745
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
51 can be fit into 500 9 times, resulting in a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 1654.6274509
If we take 459 away from 500, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 13:
51 can be fit into 410 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 1654.62745098
If we subtract 408 from 410, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 1654.62745098 with a balance of 2e-09.
