8666352 divided by 424 
We want to figure out the number of times 8666352 can be divided by 424.

On to step 1:
The number 424 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 424

On to step 2:
86 divided by 424 is 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Append the next digit (6) from the dividend to 86 and continue with: 866 / 424

Step 3:
866 divided by 424 is 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 18 after subtracting 848 from 866.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 424

Step 4:
When dividing 186 by 424, we get 0 with a remainder of 186.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 186, we get 186.
Fetch the next digit (3) from the dividend, attach it to 186 and continue: 1863 / 424

Advancing to step 5:
The number 424 fits into 1863 4 times, leaving a remainder of 167.
Put 4 as the next digit of the answer. 
Result so far: 204.0
Deduct 1696 from 1863 and we're left with 167.
Bring next digit (5) of the dividend behind the 167 and repeat the process: 1675 / 424

Going ahead to step 6:
424 goes into 1675 3 times with a remainder of 403.
Write down 3 as next digit of the result. 
Result so far: 2043.0
The remainder is 403 after subtracting 1272 from 1675.
Append the next digit (2) from the dividend to 403 and continue with: 4032 / 424

Advancing to step 7:
The number 424 fits into 4032 9 times, leaving a remainder of 216.
Record the quotient 9 as the next digit in the result. 
Result so far: 20439.0
Subtract 3816 from 4032 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 8:
424 can be fit into 2160 5 times, resulting in a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 20439.5
Subtract 2120 from 2160 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
400 divided by 424 is 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 20439.5
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 10:
4000 divided by 424 is 9 with a remainder of 184.
The next digit of our result is 9. 
Result so far: 20439.509
Subtract 3816 from 4000 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 11:
424 goes into 1840 4 times with a remainder of 144.
Record the quotient 4 as the next digit in the result. 
Result so far: 20439.5094
If we take 1696 away from 1840, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 12:
The number 424 fits into 1440 3 times, leaving a remainder of 168.
Write down 3 as next digit of the result. 
Result so far: 20439.50943
The remainder is 168 after subtracting 1272 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 13:
If we divide 1680 by 424, we get 3 and a remainder of 408.
Put 3 as the next digit of the answer. 
Result so far: 20439.509433
If we subtract 1272 from 1680, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Our division results in 20439.509433 with a remaining 4.08e-05.
