We look at the division of 51254 by 84 
We want to figure out the number of times 51254 can be divided by 84.

Step 1:
The number 84 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 84

Going ahead to step 2:
84 can be fit into 51 0 times, resulting in a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (2) from the dividend, attach it to 51 and continue: 512 / 84

On to step 3:
If we divide 512 by 84, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 504 from 512 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 84

Advancing to step 4:
84 can be fit into 85 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
Subtracting 84 from 85 leaves us with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 84

Let's proceed to step 5:
84 goes into 14 0 times with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 610.0
Subtracting 0 from 14 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 6:
If we divide 140 by 84, we get 1 and a remainder of 56.
Record the quotient 1 as the next digit in the result. 
Result so far: 610.1
If we take 84 away from 140, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 7:
84 can be fit into 560 6 times, resulting in a remainder of 56.
The next digit of our result is 6. 
Result so far: 610.16
Deduct 504 from 560 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 8:
560 divided by 84 is 6 with a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 610.166
If we subtract 504 from 560, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 610.166 with a remainder of 0.0056.
