Let's divide 16510174 by 666
We want to divide 16510174 by 666.

Step 1:
When dividing 1 by 666, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 666

Going ahead to step 2:
666 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 666

Advancing to step 3:
If we divide 165 by 666, we get 0 and a remainder of 165.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 165, we end up with 165.
Include the next digit (1) from the dividend after 165, then repeat: 1651 / 666

Going ahead to step 4:
1651 divided by 666 is 2 with a remainder of 319.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1332 from 1651 and we're left with 319.
Fetch the next digit (0) from the dividend, attach it to 319 and continue: 3190 / 666

Step 5:
The number 666 fits into 3190 4 times, leaving a remainder of 526.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we subtract 2664 from 3190, we get 526.
Include the next digit (1) from the dividend after 526, then repeat: 5261 / 666

Advancing to step 6:
When dividing 5261 by 666, we get 7 with a remainder of 599.
The number 7 becomes the next digit in our result. 
Result so far: 247.0
Deduct 4662 from 5261 and we're left with 599.
Append the next digit (7) from the dividend to 599 and continue with: 5997 / 666

Let's proceed to step 7:
If we divide 5997 by 666, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 2479.0
Subtract 5994 from 5997 to get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 666

Advancing to step 8:
If we divide 34 by 666, we get 0 and a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 24790.0
Subtract 0 from 34 to 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.

Going ahead to step 9:
If we divide 340 by 666, we get 0 and a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 24790.0
If we subtract 0 from 340, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 10:
666 can be fit into 3400 5 times, resulting in a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 24790.05
Deduct 3330 from 3400 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
700 divided by 666 is 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 24790.051
Deduct 666 from 700 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.

Moving on to step 12:
The number 666 fits into 340 0 times, leaving a remainder of 340.
Put 0 as the next digit of the answer. 
Result so far: 24790.051
Subtract 0 from 340 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 13:
666 goes into 3400 5 times with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 24790.05105
If we subtract 3330 from 3400, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 14:
If we divide 700 by 666, we get 1 and a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 24790.051051
The remainder is 34 after subtracting 666 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 15:
If we divide 340 by 666, we get 0 and a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 24790.051051
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 16:
The number 666 fits into 3400 5 times, leaving a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 24790.05105105
The remainder is 70 after subtracting 3330 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 24790.05105105, with a leftover of 7e-08.
