40997559 divided by 66 
Our goal is to divide 40997559 by 66.

Step 1:
66 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 66

Step 2:
When dividing 40 by 66, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 66

On to step 3:
66 goes into 409 6 times with a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 396 from 409 and we're left with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 66

Advancing to step 4:
If we divide 139 by 66, we get 2 and a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
Subtracting 132 from 139 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 66

On to step 5:
66 goes into 77 1 times with a remainder of 11.
The next digit of our result is 1. 
Result so far: 621.0
If we take 66 away from 77, we end up with 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 66

Step 6:
66 goes into 115 1 times with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 6211.0
If we take 66 away from 115, we end up with 49.
Grab the next digit (5) from the dividend, add it to 49, then carry on: 495 / 66

Let's proceed to step 7:
If we divide 495 by 66, we get 7 and a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 62117.0
If we subtract 462 from 495, we get 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 66

Advancing to step 8:
The number 66 fits into 339 5 times, leaving a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 621175.0
The remainder is 9 after subtracting 330 from 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
When dividing 90 by 66, we get 1 with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 621175.1
If we take 66 away from 90, we end up 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.

Going ahead to step 10:
66 can be fit into 240 3 times, resulting in a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 621175.13
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
When dividing 420 by 66, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 621175.136
If we take 396 away from 420, we end up 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.

On to step 12:
If we divide 240 by 66, we get 3 and a remainder of 42.
The next digit of our result is 3. 
Result so far: 621175.1363
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
420 divided by 66 is 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 621175.13636
Subtracting 396 from 420 leaves us 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 14:
240 divided by 66 is 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 621175.136363
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 15:
66 goes into 420 6 times with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 621175.1363636
Subtracting 396 from 420 leaves us 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 16:
When dividing 240 by 66, we get 3 with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 621175.13636363
If we take 198 away from 240, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 621175.13636363 and a remainder of 4.2e-08.
