66178216 divided by 251 
Our goal is to divide 66178216 by 251.

On to step 1:
The number 251 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 251

Moving on to step 2:
251 goes into 66 0 times with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 251

Advancing to step 3:
661 divided by 251 is 2 with a remainder of 159.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 502 from 661, we get 159.
Grab the next digit (7) from the dividend, add it to 159, then carry on: 1597 / 251

Going ahead to step 4:
1597 divided by 251 is 6 with a remainder of 91.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtracting 1506 from 1597 leaves us with 91.
Grab the next digit (8) from the dividend, add it to 91, then carry on: 918 / 251

Advancing to step 5:
918 divided by 251 is 3 with a remainder of 165.
The number 3 becomes the next digit in our result. 
Result so far: 263.0
Subtracting 753 from 918 leaves us with 165.
Include the next digit (2) from the dividend after 165, then repeat: 1652 / 251

Moving on to step 6:
251 can be fit into 1652 6 times, resulting in a remainder of 146.
Write down 6 as next digit of the result. 
Result so far: 2636.0
If we take 1506 away from 1652, we end up with 146.
Fetch the next digit (1) from the dividend, attach it to 146 and continue: 1461 / 251

Moving on to step 7:
When dividing 1461 by 251, we get 5 with a remainder of 206.
The next digit of our result is 5. 
Result so far: 26365.0
Subtract 1255 from 1461 to get 206.
Take the next digit (6) from the dividend and append it to 206, then repeat: 2066 / 251

Going ahead to step 8:
The number 251 fits into 2066 8 times, leaving a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 263658.0
If we subtract 2008 from 2066, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 9:
If we divide 580 by 251, we get 2 and a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 263658.2
The remainder is 78 after subtracting 502 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 10:
780 divided by 251 is 3 with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 263658.23
Subtracting 753 from 780 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 11:
The number 251 fits into 270 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 263658.231
If we take 251 away from 270, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 12:
190 divided by 251 is 0 with a remainder of 190.
Record the quotient 0 as the next digit in the result. 
Result so far: 263658.231
Deduct 0 from 190 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 13:
251 can be fit into 1900 7 times, resulting in a remainder of 143.
The number 7 becomes the next digit in our result. 
Result so far: 263658.23107
Subtracting 1757 from 1900 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Let's proceed to step 14:
1430 divided by 251 is 5 with a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 263658.231075
Subtracting 1255 from 1430 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 15:
251 goes into 1750 6 times with a remainder of 244.
The next digit of our result is 6. 
Result so far: 263658.2310756
If we take 1506 away from 1750, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 16:
If we divide 2440 by 251, we get 9 and a remainder of 181.
Use 9 as the next digit of our solution. 
Result so far: 263658.23107569
Deduct 2259 from 2440 and we're left with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

In conclusion, the division gives 263658.23107569 with a balance of 1.81e-07.
