We look at the division of 638997 by 84 
Let's see how many times 84 fits into 638997.

On to step 1:
84 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 84

Step 2:
When dividing 63 by 84, we get 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Take the next digit (8) from the dividend and append it to 63, then repeat: 638 / 84

Moving on to step 3:
638 divided by 84 is 7 with a remainder of 50.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 588 away from 638, we end up with 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 84

Step 4:
84 goes into 509 6 times with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 76.0
If we take 504 away from 509, we end up with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 84

On to step 5:
When dividing 59 by 84, we get 0 with a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 760.0
If we subtract 0 from 59, we get 59.
Bring next digit (7) of the dividend behind the 59 and repeat the process: 597 / 84

Step 6:
597 divided by 84 is 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 7607.0
Subtract 588 from 597 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
When dividing 90 by 84, we get 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 7607.1
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
84 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 7607.1
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
600 divided by 84 is 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 7607.107
The remainder is 12 after subtracting 588 from 600.
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:
84 goes into 120 1 times with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 7607.1071
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
84 can be fit into 360 4 times, resulting in a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 7607.10714
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 can be fit into 240 2 times, resulting in a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 7607.107142
Subtracting 168 from 240 leaves us 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:
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: 7607.1071428
If we take 672 away from 720, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
84 goes into 480 5 times with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 7607.10714285
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.

The quotient of the division is 7607.10714285, and the remainder is 6e-08.
