Let's divide 636996 by 42
Our goal is to divide 636996 by 42.

Let's proceed to step 1:
If we divide 6 by 42, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 42

Going ahead to step 2:
63 divided by 42 is 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 42 from 63, we get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 42

Step 3:
When dividing 216 by 42, we get 5 with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 210 from 216, we get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 42

Let's proceed to step 4:
42 can be fit into 69 1 times, resulting in a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 151.0
If we take 42 away from 69, we end up with 27.
Append the next digit (9) from the dividend to 27 and continue with: 279 / 42

Advancing to step 5:
If we divide 279 by 42, we get 6 and a remainder of 27.
The next digit of our result is 6. 
Result so far: 1516.0
The remainder is 27 after subtracting 252 from 279.
Append the next digit (6) from the dividend to 27 and continue with: 276 / 42

Let's proceed to step 6:
If we divide 276 by 42, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 15166.0
Deduct 252 from 276 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.

Step 7:
42 can be fit into 240 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 15166.5
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
If we divide 300 by 42, we get 7 and a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 15166.57
Subtracting 294 from 300 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.

Step 9:
42 goes into 60 1 times with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 15166.571
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
When dividing 180 by 42, we get 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 15166.5714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
42 can be fit into 120 2 times, resulting in a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 15166.57142
If we take 84 away from 120, we end up 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.

Moving on to step 12:
42 can be fit into 360 8 times, resulting in a remainder of 24.
The next digit of our result is 8. 
Result so far: 15166.571428
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.

Moving on to step 13:
240 divided by 42 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 15166.5714285
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 15166.57142857
If we subtract 294 from 300, 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.

The final result is 15166.57142857 with a remainder of 6e-09.
