638985 divided by 84 
We want to figure out the number of times 638985 can be divided by 84.

Moving on to step 1:
84 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 84

Step 2:
The number 84 fits into 63 0 times, leaving a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Bring next digit (8) of the dividend behind the 63 and repeat the process: 638 / 84

Let's proceed to step 3:
The number 84 fits into 638 7 times, leaving a remainder of 50.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 588 from 638 leaves us with 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 84

On to step 4:
If we divide 509 by 84, we get 6 and a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 76.0
The remainder is 5 after subtracting 504 from 509.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 84

Advancing to step 5:
If we divide 58 by 84, we get 0 and a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 760.0
Deduct 0 from 58 and we're left with 58.
Fetch the next digit (5) from the dividend, attach it to 58 and continue: 585 / 84

Let's proceed to step 6:
84 can be fit into 585 6 times, resulting in a remainder of 81.
Record the quotient 6 as the next digit in the result. 
Result so far: 7606.0
Deduct 504 from 585 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 7:
84 can be fit into 810 9 times, resulting in a remainder of 54.
The next digit of our result is 9. 
Result so far: 7606.9
Deduct 756 from 810 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
540 divided by 84 is 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 7606.96
The remainder is 36 after subtracting 504 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
84 goes into 360 4 times with a remainder of 24.
The next digit of our result is 4. 
Result so far: 7606.964
If we take 336 away from 360, we end up 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.

Step 10:
84 goes into 240 2 times with a remainder of 72.
The next digit of our result is 2. 
Result so far: 7606.9642
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.

Going ahead to step 11:
When dividing 720 by 84, we get 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 7606.96428
Subtract 672 from 720 to 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 12:
84 can be fit into 480 5 times, resulting in a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 7606.964285
If we subtract 420 from 480, 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.

Step 13:
600 divided by 84 is 7 with a remainder of 12.
The next digit of our result is 7. 
Result so far: 7606.9642857
Subtract 588 from 600 to 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.

Moving on to step 14:
84 goes into 120 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 7606.96428571
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.

After the division, we end up with 7606.96428571 and a remainder of 3.6e-08.
