We're dividing 521859 by 84 
We're looking to find how many times 84 goes into 521859.

Let's proceed to step 1:
84 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 84

Going ahead to step 2:
If we divide 52 by 84, we get 0 and a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Grab the next digit (1) from the dividend, add it to 52, then carry on: 521 / 84

Advancing to step 3:
If we divide 521 by 84, we get 6 and a remainder of 17.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 504 from 521 to get 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 84

Step 4:
84 goes into 178 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
If we take 168 away from 178, we end up with 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 84

On to step 5:
105 divided by 84 is 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 621.0
Subtract 84 from 105 to get 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 84

On to step 6:
219 divided by 84 is 2 with a remainder of 51.
Put 2 as the next digit of the answer. 
Result so far: 6212.0
If we take 168 away from 219, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
If we divide 510 by 84, we get 6 and a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 6212.6
If we subtract 504 from 510, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
The number 84 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 6212.6
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
The number 84 fits into 600 7 times, leaving a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 6212.607
If we subtract 588 from 600, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
When dividing 120 by 84, we get 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 6212.6071
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
When dividing 360 by 84, we get 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 6212.60714
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
84 goes into 240 2 times with a remainder of 72.
The next digit of our result is 2. 
Result so far: 6212.607142
If we take 168 away from 240, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 13:
84 can be fit into 720 8 times, resulting in a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 6212.6071428
If we subtract 672 from 720, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
480 divided by 84 is 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 6212.60714285
Subtract 420 from 480 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 6212.60714285 with a remaining 6e-08.
