We look at the division of 10638814 by 66 
Let's see how many times 66 fits into 10638814.

Going ahead to step 1:
When dividing 1 by 66, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 66

Going ahead to step 2:
When dividing 10 by 66, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 66

Let's proceed to step 3:
When dividing 106 by 66, we get 1 with a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 66 from 106 leaves us with 40.
Append the next digit (3) from the dividend to 40 and continue with: 403 / 66

Going ahead to step 4:
66 goes into 403 6 times with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we take 396 away from 403, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 66

Moving on to step 5:
The number 66 fits into 78 1 times, leaving a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 161.0
Subtracting 66 from 78 leaves us with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 66

Advancing to step 6:
If we divide 128 by 66, we get 1 and a remainder of 62.
The next digit of our result is 1. 
Result so far: 1611.0
Subtract 66 from 128 to get 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 66

Advancing to step 7:
If we divide 621 by 66, we get 9 and a remainder of 27.
The next digit of our result is 9. 
Result so far: 16119.0
Deduct 594 from 621 and we're left with 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 66

Moving on to step 8:
The number 66 fits into 274 4 times, leaving a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 161194.0
Subtract 264 from 274 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
100 divided by 66 is 1 with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 161194.1
If we subtract 66 from 100, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
When dividing 340 by 66, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 161194.15
Deduct 330 from 340 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
When dividing 100 by 66, we get 1 with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 161194.151
Subtracting 66 from 100 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 12:
When dividing 340 by 66, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 161194.1515
The remainder is 10 after subtracting 330 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
If we divide 100 by 66, we get 1 and a remainder of 34.
The next digit of our result is 1. 
Result so far: 161194.15151
Deduct 66 from 100 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 14:
If we divide 340 by 66, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 161194.151515
Deduct 330 from 340 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 15:
When dividing 100 by 66, we get 1 with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 161194.1515151
If we take 66 away from 100, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 16:
When dividing 340 by 66, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 161194.15151515
Subtract 330 from 340 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 161194.15151515 with a remaining 1e-08.
