We're dividing 66778850 by 251 
Let's see how many times 251 fits into 66778850.

Going ahead to step 1:
If we divide 6 by 251, we get 0 and 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 / 251

Advancing to step 2:
66 divided by 251 is 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Append the next digit (7) from the dividend to 66 and continue with: 667 / 251

Moving on to step 3:
When dividing 667 by 251, we get 2 with a remainder of 165.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 502 from 667 and we're left with 165.
Grab the next digit (7) from the dividend, add it to 165, then carry on: 1657 / 251

Step 4:
The number 251 fits into 1657 6 times, leaving a remainder of 151.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Subtracting 1506 from 1657 leaves us with 151.
Bring next digit (8) of the dividend behind the 151 and repeat the process: 1518 / 251

Moving on to step 5:
If we divide 1518 by 251, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 266.0
If we subtract 1506 from 1518, we get 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 251

Moving on to step 6:
The number 251 fits into 128 0 times, leaving a remainder of 128.
Put 0 as the next digit of the answer. 
Result so far: 2660.0
Subtracting 0 from 128 leaves us with 128.
Include the next digit (5) from the dividend after 128, then repeat: 1285 / 251

Moving on to step 7:
The number 251 fits into 1285 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 26605.0
If we subtract 1255 from 1285, we get 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 251

Step 8:
300 divided by 251 is 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 266051.0
If we take 251 away from 300, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 9:
The number 251 fits into 490 1 times, leaving a remainder of 239.
The next digit of our result is 1. 
Result so far: 266051.1
Deduct 251 from 490 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Moving on to step 10:
If we divide 2390 by 251, we get 9 and a remainder of 131.
Put 9 as the next digit of the answer. 
Result so far: 266051.19
Deduct 2259 from 2390 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 11:
251 goes into 1310 5 times with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 266051.195
Subtracting 1255 from 1310 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 12:
251 goes into 550 2 times with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 266051.1952
If we subtract 502 from 550, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
251 can be fit into 480 1 times, resulting in a remainder of 229.
The number 1 becomes the next digit in our result. 
Result so far: 266051.19521
The remainder is 229 after subtracting 251 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

On to step 14:
The number 251 fits into 2290 9 times, leaving a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 266051.195219
Subtract 2259 from 2290 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 15:
If we divide 310 by 251, we get 1 and a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 266051.1952191
The remainder is 59 after subtracting 251 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 16:
251 goes into 590 2 times with a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 266051.19521912
The remainder is 88 after subtracting 502 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final result is 266051.19521912 with a remainder of 8.8e-08.
