We're dividing 63657911 by 42 
We want to figure out the number of times 63657911 can be divided by 42.

On to step 1:
42 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
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

On to step 2:
42 can be fit into 63 1 times, resulting in a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 42 from 63 and we're left with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 42

On to step 3:
42 goes into 216 5 times with a remainder of 6.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 210 from 216 to get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 42

Advancing to step 4:
When dividing 65 by 42, we get 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 151.0
If we subtract 42 from 65, we get 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 42

Let's proceed to step 5:
The number 42 fits into 237 5 times, leaving a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 1515.0
Subtract 210 from 237 to get 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 42

Moving on to step 6:
42 can be fit into 279 6 times, resulting in a remainder of 27.
Put 6 as the next digit of the answer. 
Result so far: 15156.0
If we subtract 252 from 279, we get 27.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 42

Going ahead to step 7:
42 can be fit into 271 6 times, resulting in a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 151566.0
Subtracting 252 from 271 leaves us with 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 42

Advancing to step 8:
42 can be fit into 191 4 times, resulting in a remainder of 23.
The number 4 becomes the next digit in our result. 
Result so far: 1515664.0
Subtract 168 from 191 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
When dividing 230 by 42, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 1515664.5
The remainder is 20 after subtracting 210 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
When dividing 200 by 42, we get 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 1515664.54
Subtracting 168 from 200 leaves us 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.

Moving on to step 11:
The number 42 fits into 320 7 times, leaving a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 1515664.547
If we take 294 away from 320, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 12:
If we divide 260 by 42, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 1515664.5476
Subtracting 252 from 260 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
When dividing 80 by 42, we get 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 1515664.54761
If we subtract 42 from 80, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 14:
42 goes into 380 9 times with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 1515664.547619
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 15:
When dividing 20 by 42, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 1515664.547619
Subtracting 0 from 20 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.

On to step 16:
If we divide 200 by 42, we get 4 and a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 1515664.54761904
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.

Our division results in 1515664.54761904 with a remaining 3.2e-08.
