We look at the division of 66106576 by 406 
We want to figure out the number of times 66106576 can be divided by 406.

Moving on to step 1:
406 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 406

Moving on to step 2:
406 can be fit into 66 0 times, resulting in a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Grab the next digit (1) from the dividend, add it to 66, then carry on: 661 / 406

Moving on to step 3:
406 can be fit into 661 1 times, resulting in a remainder of 255.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 406 from 661, we get 255.
Append the next digit (0) from the dividend to 255 and continue with: 2550 / 406

Going ahead to step 4:
406 can be fit into 2550 6 times, resulting in a remainder of 114.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 2436 from 2550 and we're left with 114.
Include the next digit (6) from the dividend after 114, then repeat: 1146 / 406

Let's proceed to step 5:
1146 divided by 406 is 2 with a remainder of 334.
The next digit of our result is 2. 
Result so far: 162.0
If we take 812 away from 1146, we end up with 334.
Include the next digit (5) from the dividend after 334, then repeat: 3345 / 406

On to step 6:
406 goes into 3345 8 times with a remainder of 97.
Use 8 as the next digit of our solution. 
Result so far: 1628.0
If we subtract 3248 from 3345, we get 97.
Bring next digit (7) of the dividend behind the 97 and repeat the process: 977 / 406

On to step 7:
The number 406 fits into 977 2 times, leaving a remainder of 165.
The next digit of our result is 2. 
Result so far: 16282.0
The remainder is 165 after subtracting 812 from 977.
Fetch the next digit (6) from the dividend, attach it to 165 and continue: 1656 / 406

Moving on to step 8:
If we divide 1656 by 406, we get 4 and a remainder of 32.
The next digit of our result is 4. 
Result so far: 162824.0
Subtracting 1624 from 1656 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
406 can be fit into 320 0 times, resulting in a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 162824.0
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 10:
If we divide 3200 by 406, we get 7 and a remainder of 358.
Use 7 as the next digit of our solution. 
Result so far: 162824.07
If we subtract 2842 from 3200, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 11:
406 can be fit into 3580 8 times, resulting in a remainder of 332.
Record the quotient 8 as the next digit in the result. 
Result so far: 162824.078
If we subtract 3248 from 3580, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 12:
The number 406 fits into 3320 8 times, leaving a remainder of 72.
The next digit of our result is 8. 
Result so far: 162824.0788
The remainder is 72 after subtracting 3248 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

In conclusion, the division gives 162824.0788 with a balance of 0.00072.
