We look at the division of 66855926 by 312 
We're looking to find how many times 312 goes into 66855926.

Advancing to step 1:
6 divided by 312 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 312

Going ahead to step 2:
When dividing 66 by 312, we get 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Take the next digit (8) from the dividend and append it to 66, then repeat: 668 / 312

Moving on to step 3:
The number 312 fits into 668 2 times, leaving a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 624 from 668 and we're left with 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 312

Let's proceed to step 4:
If we divide 445 by 312, we get 1 and a remainder of 133.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 312 from 445 and we're left with 133.
Append the next digit (5) from the dividend to 133 and continue with: 1335 / 312

Going ahead to step 5:
The number 312 fits into 1335 4 times, leaving a remainder of 87.
Put 4 as the next digit of the answer. 
Result so far: 214.0
If we take 1248 away from 1335, we end up with 87.
Include the next digit (9) from the dividend after 87, then repeat: 879 / 312

Advancing to step 6:
If we divide 879 by 312, we get 2 and a remainder of 255.
Put 2 as the next digit of the answer. 
Result so far: 2142.0
The remainder is 255 after subtracting 624 from 879.
Grab the next digit (2) from the dividend, add it to 255, then carry on: 2552 / 312

Moving on to step 7:
When dividing 2552 by 312, we get 8 with a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 21428.0
If we take 2496 away from 2552, we end up with 56.
Bring next digit (6) of the dividend behind the 56 and repeat the process: 566 / 312

Let's proceed to step 8:
The number 312 fits into 566 1 times, leaving a remainder of 254.
Use 1 as the next digit of our solution. 
Result so far: 214281.0
The remainder is 254 after subtracting 312 from 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Moving on to step 9:
312 goes into 2540 8 times with a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 214281.8
The remainder is 44 after subtracting 2496 from 2540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
If we divide 440 by 312, we get 1 and a remainder of 128.
Write down 1 as next digit of the result. 
Result so far: 214281.81
The remainder is 128 after subtracting 312 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 11:
When dividing 1280 by 312, we get 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 214281.814
The remainder is 32 after subtracting 1248 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
The number 312 fits into 320 1 times, leaving a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 214281.8141
Deduct 312 from 320 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
When dividing 80 by 312, we get 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 214281.8141
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
312 goes into 800 2 times with a remainder of 176.
Use 2 as the next digit of our solution. 
Result so far: 214281.814102
Subtracting 624 from 800 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 15:
If we divide 1760 by 312, we get 5 and a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 214281.8141025
If we take 1560 away from 1760, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 16:
The number 312 fits into 2000 6 times, leaving a remainder of 128.
Use 6 as the next digit of our solution. 
Result so far: 214281.81410256
If we subtract 1872 from 2000, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

In conclusion, the division gives 214281.81410256 with a balance of 1.28e-07.
