We're dividing 66910398 by 63 
We're looking to find how many times 63 goes into 66910398.

Step 1:
63 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 63

Moving on to step 2:
When dividing 66 by 63, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 63 from 66 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 63

Let's proceed to step 3:
When dividing 39 by 63, we get 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 39, we end up with 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 63

Going ahead to step 4:
When dividing 391 by 63, we get 6 with a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
If we subtract 378 from 391, we get 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 63

Advancing to step 5:
If we divide 130 by 63, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 1062.0
If we subtract 126 from 130, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 63

Let's proceed to step 6:
If we divide 43 by 63, we get 0 and a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 10620.0
The remainder is 43 after subtracting 0 from 43.
Fetch the next digit (9) from the dividend, attach it to 43 and continue: 439 / 63

Advancing to step 7:
If we divide 439 by 63, we get 6 and a remainder of 61.
The next digit of our result is 6. 
Result so far: 106206.0
If we take 378 away from 439, we end up with 61.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 63

On to step 8:
63 can be fit into 618 9 times, resulting in a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 1062069.0
Deduct 567 from 618 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 9:
510 divided by 63 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 1062069.8
If we take 504 away from 510, we end up 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.

Advancing to step 10:
When dividing 60 by 63, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 1062069.8
Subtract 0 from 60 to 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.

Going ahead to step 11:
600 divided by 63 is 9 with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 1062069.809
If we subtract 567 from 600, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 12:
When dividing 330 by 63, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1062069.8095
If we subtract 315 from 330, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
The number 63 fits into 150 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 1062069.80952
The remainder is 24 after subtracting 126 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
The number 63 fits into 240 3 times, leaving a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 1062069.809523
If we take 189 away from 240, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 15:
63 can be fit into 510 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 1062069.8095238
The remainder is 6 after subtracting 504 from 510.
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 16:
63 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 1062069.8095238
Subtracting 0 from 60 leaves us 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.

Our division results in 1062069.8095238 with a remaining 6e-08.
