51578 divided by 84 
We're looking to find how many times 84 goes into 51578.

Going ahead to step 1:
84 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 84

Going ahead to step 2:
84 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 84

Let's proceed to step 3:
If we divide 515 by 84, we get 6 and a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 504 from 515, we get 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 84

Moving on to step 4:
If we divide 117 by 84, we get 1 and a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
Deduct 84 from 117 and we're left with 33.
Bring next digit (8) of the dividend behind the 33 and repeat the process: 338 / 84

Going ahead to step 5:
84 can be fit into 338 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 614.0
Subtract 336 from 338 to 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.

Going ahead to step 6:
84 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 614.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
84 can be fit into 200 2 times, resulting in a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 614.02
If we subtract 168 from 200, 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.

Step 8:
84 can be fit into 320 3 times, resulting in a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 614.023
Subtracting 252 from 320 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 9:
84 can be fit into 680 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 614.0238
If we take 672 away from 680, 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.

On to step 10:
The number 84 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 614.0238
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
84 can be fit into 800 9 times, resulting in a remainder of 44.
The next digit of our result is 9. 
Result so far: 614.023809
The remainder is 44 after subtracting 756 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 12:
84 can be fit into 440 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 614.0238095
Deduct 420 from 440 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
When dividing 200 by 84, we get 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 614.02380952
If we subtract 168 from 200, 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.

After the division, we end up with 614.02380952 and a remainder of 3.2e-08.
