We're dividing 638171 by 84 
Let's see how many times 84 fits into 638171.

Advancing to step 1:
84 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 84

Let's proceed to step 2:
The number 84 fits into 63 0 times, leaving a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Grab the next digit (8) from the dividend, add it to 63, then carry on: 638 / 84

Advancing to step 3:
The number 84 fits into 638 7 times, leaving a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 588 from 638 and we're left with 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 84

Step 4:
84 goes into 501 5 times with a remainder of 81.
Write down 5 as next digit of the result. 
Result so far: 75.0
Subtract 420 from 501 to get 81.
Take the next digit (7) from the dividend and append it to 81, then repeat: 817 / 84

On to step 5:
817 divided by 84 is 9 with a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 759.0
Deduct 756 from 817 and we're left with 61.
Include the next digit (1) from the dividend after 61, then repeat: 611 / 84

Moving on to step 6:
84 can be fit into 611 7 times, resulting in a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 7597.0
The remainder is 23 after subtracting 588 from 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
230 divided by 84 is 2 with a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 7597.2
If we subtract 168 from 230, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 8:
If we divide 620 by 84, we get 7 and a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 7597.27
Deduct 588 from 620 and we're left 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.

Going ahead to step 9:
The number 84 fits into 320 3 times, leaving a remainder of 68.
The next digit of our result is 3. 
Result so far: 7597.273
The remainder is 68 after subtracting 252 from 320.
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 10:
680 divided by 84 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 7597.2738
Subtract 672 from 680 to get 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 11:
80 divided by 84 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 7597.2738
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
84 goes into 800 9 times with a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 7597.273809
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 13:
84 can be fit into 440 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 7597.2738095
Subtracting 420 from 440 leaves us 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 14:
200 divided by 84 is 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 7597.27380952
Deduct 168 from 200 and we're left 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.

The final result is 7597.27380952 with a remainder of 3.2e-08.
